I've had my desktop computer for about one year now. It is an Acer Aspire E380. On Saturday afternoon, it was going a bit slow so I decided to restart it. However, once it turned off, it will no longer turn on and boot up.
The power button usually lights up, but now it does not. But, the decorative words "Aspire" at the bottom of the tower still lights up. The DVD drive still opens, and a few lights blink on start up as usual.
The screen is blank. All of the fans seem to go, except for one. It is the one in the center of the computer on top of a group of metal prongs. It spins upon power up but stops. The power supply fan runs, the other fan runs too.
I have made sure everything is plugged in, and tried plugging it into different outlets. I can't boot from a CD, the keyboard doesn't turn on and neither does the mouse.
As far as starting up goes, everything sounds normal. No beeps or clicks to hint at harddrive failure. Sometimes when I try to start it up nothing comes on but the center fan on the metal prongs (the one that would run for only a few seconds) goes on full blast until I turn it off.
If everything seems to be going, what is stopping it from booting up?
I have learned a lot from your posts and am glad you are so attentive to respond to everyone. I read a bit back in the post about someone having a similar problem with an ASUS P5N motherboard but couldn't find the outcome.
My motherboard is an ASUS P5N-E SLI . It has been a wonderful motherboard. Today, with no warning, while trying to turn on the computer: no video output, no beeps, all fans are on, no startup. So, I removed my video card, audio card, memory, and extra case fan. Still no beeps. Motherboard LED is lit, hard drives are working, dvd drive is working. I assume it's not the PSU.
Now, according to you, it's either the motherboard or the CPU. I have a large heatsink on my CPU, no fan. This allows me to feel the metal on the heatsink right on top of the CPU and it does not get warm when I turn it on. So, this means the CPU is bad, right? But, is it not possible that damage to the motherboard is preventing power from reaching the CPU? Let me know, please. Then I can decide whether to buy a new CPU or a new Motherboard.
Oh, I haven't tried replacing the battery on the motherboard. Can this still be a possible problem?
No easy solution to your problem. One would need hands on access to the computer. It could be the power supply the motherboard takes different voltages than the fans. The fans on proves nothing about the power supply.
If you can't swap out the power supply (my first option) then Take it to a repair shop.
Hey, I just had the problem as well, not sure what happened......I came home from work, turned on the comp, looked fine, went to jump in the shower, came back and it seemed my comp was stuck in hibernation, so I turned it off, and got the same problem. The lights would come on, all the fans would start running, but it would stay black on my monitor and I heard no beeps/boot. I got on another comp in the house and started forum searching and halfway found my answer.....
Now this problably has been said already, but I havent had the time to read through all the posts, but it turns out that when I removed my PCIe video card, and plugged my monitor up to the onboard card on my mobo, the computer started up fine! So I cleaned the PCIe card and tried to put it back in and start up the comp again, only to have the black screen, no boot thing happen again, but this time I noticed the fan on the card was trying to spin, but couldnt, kept getting stuck. Tried cleaning it more to no avail...
So my conclusion is either the card/fan itself is dead, or my PCIe slot on my mobo is dead, but w/o it in the slot my computer runs just like it did, I'll have to find out the issue when I have more time. Hope this helps
.. ive been having the same problem as everybody else (for the most part)
i feel ive taken all the necessary steps but I want to be 110% sure that ive come to the correct conclusion. Mainly because the computer is not actually mine. I'm just more technical than the owner and have a decent common knowledge about computers and electronics
so here's what happens ..
PC turns on
PSU fan is fully functional
Hard disk spins
DVD drive lights up, opens and closes
when first powering on the PC the CPU fan spins for a second but only for a second and then stops
Manual shut down is not possible .. ive held down the power button for 2 minutes straight and no shutdown occurs
PC does not boot ..
the monitor recognizes that its connected to a video card but immediately says that its going to sleep
this is what ive done so far ..
i've disconnected the RAM and turned on the computer ... no beep .. no nothing
ive attempted to clean the RAM with an eraser .. no luck
i've attempted switching ports that the RAM is plugged into .. no luck
i've tried switching the PSU with one that I KNOW works well and I get the same results
i've removed the ethernet card and restarted the PC .. no luck
I've removed and reinserted the BIOS battery located on the MoBo .. no luck
I've cleaned out all the dust from the fans and boards and once again .. no luck
i can't seem to remove the CPU heat sinc from the CPU to do the heat test .. BUT .. ive left the PC running (everything connected) and I can feel the heat sinc heating up after about a few minutes .. which leads me to believe that the CPU is fully functional
i cant blame it on the Graphics card because graphics is all on board
process of elimination says that the Mobo is fried and needs to be replaced
.. so most people would say, "open and shut case, Johnson. What the heck is your question?"
well, its the CPU fan
the PC has been running for a few minutes now, the CPU is obviously heating up and the cooling fan hasn't kicked on yet.
so I attempt to spin the cooling fan manually (with just my fingers) and the fan continues spinning but at very low RPMs .. probably not even quick enough to cool a snowball in the north pole
.. so my question is .. (finally)
is the CPU cooling fan being effected by the incapabilities of the MoBo?
or do I have a secondary problem that needs to be addressed before I can confidently say that I have pinpointed all of the problems with this PC
once again .. i'd like to be 110% sure of what the exact problem is here, mainly because the computer doesnt belong to me .. and to tell a friend he has to replace his MoBo and then find out afterwards that wasn't even the problem is nothing short of .. "messed up"
to have him replace his MoBo .. solve his problems for a week or two and then have his CPU blow up on him
im hoping that other users having similar problems can read this post and see it as sort'of a checklist of things that could possibly be the problem and their solution
PC is a Acer aspire T180 and is obviously completely stock
it runs an AMD athalon64 3800+
after reading all 7 pages of this thread ive come to the conclusion that this is a pretty common problem with Acer PCs. I know what brand of computer NEVER to buy
if anyone has any questions or comments that could help my situation they would be greatly appreciated
Although not a member of this forum, I booted my cpu and experienced the same issue. Even using a system restore disc I made did not work. I removed all 3 ram modules, clean them with the eraser and on my next attempted startup - my cpu worked perfectly. Amazing. While I was in the CPU, I cleaned everything. THanks for the tip.
This discussion has a lot of great information, but I'm still having problems. My computer powers on but only boots some of the time. This system is a few years old. My hard drive had issues, so I bought a new one and decided to upgrade memory too.
I'm having trouble with installing Windows XP. I can boot from CD, and the computer goes through formatting the hard drive and loading setup files. When the setup needs to restart, the monitor goes to sleep. The power is still on, fans running, lights on - but no reboot.
My processor temp is normal and the fan is running. I've tried swapping memory, CD drives, IDE cables. I have removed all the PCI cards and use on-board video. I switched from the power strip to the wall outlet. I reset the bios settings.
When I manually restart and try to continue the install (by selecting repair), the setup starts inspecting my system and the monitor goes to sleep as described above. And some times when I power off and back on manually, the fans come on but the computer doesn't do anything (bios doesn't load).
I would appreciate any other help/suggestions, or at least some degree of certainty that the motherboard is the culprit and that I should look for a replacement.
My family and I have a HP computer, and it was running perfectly fine until this morning. When starting up the computer, no output accessories (keyboard, mouse, monitor) would start up. The keyboard and mouse don't light up like it should, however the monitor goes on but then says that it cannot find a signal, then goes to a black screen. I tried your method of removing the RAM and using the eraser, but that did no help. However, this has happened the night before. So I rebooted it several times, and I finally found a signal with my monitor and everything was functioning perfectly. So, my question is .... what might be causing this? Because it surely isn't the RAM.
i need help! one day my pc was working fine. then I turned it off and later when I tried to turn it back on it wouldnt boot. the fans come on, the hdd light flashes twice, but the led on the power button doesnt come on. I took out my ram and my motherboard beeped twice... is it supposed to beep more? and I also tried the eraser thing. I took out the cmos jumper, turned my pc on then off, and replaced the jumper. still doesnt work. what would be wrong? the main difference I see from all the other people posting on this thread is that the led on my power button doesnt come on... (not the power supply, but the button itself on the front of the pc)
Here is my situation. I have a HP Pavillion 1473w. Recently I went to use it and the mouse wasn't working. I thought the batteries but noticed the reciever lights were not on. I shut it down and it wouldn't come back up. I get a black screen. The fans come on and I hear the dvd drive and can open the drive. The motherboard is an ECS RC410-M.
Other things that I have checked
Monitor works on another computer so I ruled out the cable and monitor (swapped cables also)
I tried resetting the bios via hp recommendation of remove power cable and holding button in for 5 seconds.
I also tried removing the power cord, moving the jumper over, pressed the button 2-3 times, move the jumper back and no change.
I've removed the modem card which was not in use and tried adding a working video card. No change. Everything is built in so there are no cards hook in right now.
I removed the cpu fan and started it for a couple of seconds and felt the cpu heating.
I jumped the 24 pin connector on the board and the powersupply fan worked. Also the light on the power supply is on.
I tested the 4 pin motherboard connector, all the molex connector and jumped the 24 pin connector and tested all except black, gray don't recall a brown using a voltmeter and everything was reading at 3.3, 5 or 12
I have 2 memory cards both were swapped, used individually in both, and I used an eraser on the gold pins, no change.
I removed the memory cards and powered on but didn't hear any beeps. I see the speaker on the board and assume it is working.
I have also removed the battery and tested it on a voltmeter to see that it worked. I believe the reading was around 3
My guess is the board is bad. One bit of info that I don't understand is the switch on the front of the case is a circle and it turns blue, there is also a orange light. When I push in the switch the light flashes blue but then goes out. I believe normally it would turn blue and stay on until you shut off the pc. I'm not 100% sure that it worked like that normally but am pretty sure. I ask as I don't know if that could indicate anything or if a faulty switch could cause problems like mine.
If the board is the problem, I had planned on ordering the ECS RC410-M board online since it was the same board. Am I correct that since the board is the same that I shouldn't have any issue with booting up? There isn't a windows xp disc but I have the 2 dvds that were burned when I bought the pc new.
Any ideas or other things I should test for? I don't want to order a board is that is not the problem.
I am having a similar problem. The computer doesn't seem to boot up. Lights come on, fans run, but no light on the mouse (usb) and monitor says "power saving mode." The lights on the keyboard do come on though. I did the CMOS reset. No success. I removed the RAM and got the repeated beeping. While it was out I tried the eraser trick, but still no luck. When I tested to see if the processor warmed up, it took about 15 seconds to turn luke warm (without the heat sink). I tried this on another computer and it got too hot to touch within about 3 seconds. I wasn't sure if this indicated a CPU problem or if there just wasn't too much to process since it wasn't booting so it didn't heat up.
One other major suspect here... About 3 months ago I replace the video card when the old one started messing up. It performed well all that time. I tried removing the card (I didn't have another to replace it with so I just left the AGP slot empty) and the computer acted the same way. I'm not sure if a computer can boot without a video card, but it didn't seem to make any difference.
1. My computer froze. so I restart.
2. It would power on, but would not boot.
(no signal to monitors.)
3. I checked all cables, followed all your steps.
4. When I moved the RAM around it loaded up normal again. (long beep with no RAM.. yay!)
5. After about 10 min it crashed again.
6. I moved the RAM again and it loaded again.
7. After about 10 min I get blue screen.
8. I have tried moving the Memory over and over, but I cannot get it to boot up like it did in steps 4 and 6.
I was hopeing for a suggestion from you DJ ASKSHAY. I have two RAM cards and neither work in any slot now. (i only have 2 slots)
Hope u might help me got the same problem as above my dell dimension 5000 stoped working, first of all the power light start flashing amber fan stopped working only move for while and stopped . following the MOBO specification find out that I internal power problem my exist , disconnected all memory, HDD power , and all cards, after that the power lights start lighting STILL amber colour, fan start working but thats all, nothing happened, started plug in one component after another and nothing, still the same colour in manual said thet if light is like that device might be malfunctioning or incorrectly installed but all devices was unplaged except CPU and still the same problem, take the processor fan off, CPU is getting hot, presume is ok, so is this a MOBO failure ???? please let me know. thank you
I have gateway 507gr One day it wouldn't start/ No BIOS, no fans, no beeps, dead.
I changed the battery drained the power - nothing
I shorted the PSU green to black and the PSU fan runs, but won't run the computer - nothing
I bought a higher wattage PSU from Best Cry and - nothing
Changed out the RAM - Nothing
The LED light on the MOBO is lit and that is the only indication that any power is getting that far. Should I take off the heatsink fan and feel the processor? If it is cold then it is dead and I need a new MOBO correct?
Thank you so much for all the excellent options that you provided in your responses in this thread. I tried almost all the methods that you mentioned including using the eraser method on my memory modules but to no avail. I was about to go out and buy a new motherboard but then I thought of using the eraser method on the GPU pins and voila, everything is back the way it is supposed to be.
- when I power up the pc, nothing shows up on screen and nothing loads. however the fan speed becomes very fast. usually it takes a couple of manual reset to make it work.
- when it's supposedly made to work, the fan speed will go very fast for about 1-2 secs then goes back to the
normal speed, and that's how I know when to stop the reset.
- the system will then work fine and load to desktop.
- however from time to time, even when I do like 20 over resets, it wouldn't work. (which is happening right now)
how I try to fix:
- somehow I think it may be ram related, so I usually pluck out all the rams. I have 2x 256 and 2x 512 on it which it usually work fine.
- I tried the eraser method on the rams but it would still take a couple of resets for each pair to work. right at
the moment having either 2x 256 pair or 2x 512 is working only. I had tried to connect all 4 rams back, but
somehow it wouldn't start after 20 over resets.
- going to attempt to fix it again right now.
- even when the pc successfully bypass the fast running fan speed, it may hang at the windows screen while loading to the desktop or just hang before desktop gets completely loaded.
- i'm not sure which issue happened first but they seem to be happening together.
- I usually expect 1-5 times of screen hang before a success boot, with each hang requiring a reboot.
- however as my system stop working today, fixing in either 2x 256 pair or 2x 512 is making one attempt success boot.
Please suggest how could I fix this..
Thanks for looking through =)
I did the processor test a second ago, it didnt seem to get hot at all, no. It was probably about 10 seconds that I left it on for. I didn't want to leave it on for too long though because I saw that you said it could damage the cpu, and I just got it today :(
SPK 4-Pin is the one on the Q-Connector right? If so it's hooked up, I even took it out once and put it back in just to make sure.
Could I maybe get you email or I can give you mine so we can talk more in depth about this? I would really appreciate it. I'm really in dire need of help, I was really looking forward to using this machine :(
