1. check the RAM is seated
2. Try any other RAM
3. still the same problem check the video or graphics card , if any
4. if no graphics card and problem stiil changing it clear your CMOS by removing battery

6. still problem , check the processor heat sink
7. still problem then suggesting checking motherboard and processor

I'm clearing the cmos using the jumper - It has always worked but nothing happens now. I have tried removing the battery and shorting the pins.

The processor fan is new with brand new heat sink silicone. No pci cards inserted.

I have tried replacing the processor.
I have tried replacing the ram.
I have tried replacing the video card.
I have tried disconnecting the hard drives.

No post screen. Full lights and fans. Low hard drive activity.

What should I do?

did u installed 3ds max 2010 recently???? downloaded from torrent site ???
dragonflight- Jan 8, 2010 01:43PM
That would be an odd coincidence, as I did download and run 3ds max 2010 too, shortly before all this. In fact, when it froze in the first place, max was running...

I left my pc off for a night and came home and turned it on: the problems are as follows:-

No display; Hard drive activity not normal (not booting up); Lights and fans all working, num lock caps lock and scroll lock all flash once and at this point the display usually comes up but nothing today. I can see the ram test going on as I have corsairs XMS pro ram with activity leds. So here's what I did:

Cleared cmos with jumper on mobo. Rebooted. Same problem.
Swapped the ram for some ram I had spare. Rebooted. Same problem.
Cleared cmos with jumper on mobo. Rebooted. Same problem.
Swapped the graphics card for a crap one that uses less power. Rebooted. Same problem.
Cleared cmos with jumper on mobo. Rebooted. Same problem.
Swapped the processor for a lower speed processor. Rebooted. Same problem.
Cleared cmos with jumper on mobo. Rebooted. Same problem.
Disconnected all hard drives ( They are all SATA 1). Rebooted. Same problem.

hi guys , good news for you, because I came here to solve your problem .
Plese follow these steps:---
1. first power on the pc and check the monitor is on or not.
2. If monitor is on and not booting then
3. power off the pc ( please press the power button some second)
4. remove the memory card and power on
5. notice that the beep come from the motherboard or not if yes then your motherboard is ok and give thanks to god because you save lots of money to spent.
6. now check your SMPS.
7. if SMPS is ok then check your PCI slots
8. if any card insert in the pci slots the remove it and start your pc.

I have exactly the same problem since this morning : PC won't boot, fans are running, power and hd leds are on (no hdd activity thus), but the screen remains black...
The battery is ok, the capacitors seem to be ok too.
I don't know what to do...

It might be the problem with your RAM. take it out and clean with a rubber and kept it again. mostly it will work.
Switch of the pc ,take the cmos battery out, switch it on and switch off again. now kept the CMOS battery and swith it. It will work.
after this also it is not working means it should be the problem with the system board. system board might be dead.

hey same problem but have a fix basily just do this

1. press ctrl + alt+ delete to bring up task manger
2. Make a new task
3.In the box that pops up just type "explorer.exe" no speach marks
4. Your desktop should come up im afraid this may be to a virus you will have to do this every time it loads up so i recomend a virus scan if you have no virus protection just go here its avg free its lasts forever and suits you virus needs (getting rid off)

switching the memory didn't solve my problem. i was burning a CD and it froze, so i hit the restart button and from that last action, my computer stopped coming up... WHAT TO DO!!!!

Talked to a tech about the same issue, he stated in getting another power supply. Because of the power supply going bad it cant push everything. Get another power supply then repost if the problem is fixed or still the same. Makes since if you think about it, Its like having a weak battery on a car you have enough juice to run the electricals such as radio,turn signals, and dome lights but wont start the engine... Try getting another Power supply..... its weak.

Switch the ram around that will hopefully fix the problem. cos it fixed mine .

yes switch the ram arround dat willsolve de problem,it solve mine too. also blow out d dust out
of de CPU with you yur blower if u have1. it really solve the problem. tnks

Its the motherboard/processor/power supply. Try the motherboard first! I had to replace mine and they gave me a better motherboard, a better processor, and a better gfx card! for a discount :D

- If the fan has power, it's not your power supply unless you added new hardware, then theres a possibility.
- If the CPU LIGHT goes on, but your monitor doesn't, its your monitor. Look at your monitor light!
- Your motherboard is responsible for your RAM, GFX card, Processor, and everything else! I call it the core.
- Dust could've clogged up the PC. Clean it up!
- If all of these fail, disconnect all hard drives and all CD & DVD drives. If it boots up, you know your problem. Just reconnect one by one, following with a startup.

This answer has a 90% chance of answering your question correctly.

3 things:

1- if PC powers up (power light comes on) but nothing else happens = Bad Motherboard or Proccessor

2- Re-seat the memory

3-if PC powers up and it beeps (count the beeps and google it). One beep is normal, more then one = ERROR

4-Swap monitors to make sure it's not monitor.

ps: if you added anything new to the system like a PCI, AGP..anything. it might be a PS issue(not powerfull enough)

good luck!

mmmmm but i dont her no beep

I think it's power problem. I am the sufferer for this. My new house has some power problem it always low voltage. So I had same problem but I didn't realise this and changed RAM Processor and MB. After that I found the same problem then, I bring my PC to my office where the power is sufficient and it works. But I lost BDT8500, I am still repenting... So Please check whether you have sufficient power..

Good luck!

Hi guys, I have the same problem or similar. A few weeks ago I woke up to a frozen desktop after some drunken attempt at watching a film. Anyway I restarted the pc and no display.....everything is powered up but I get a clicking sound from the DVD drive....I have unplugged that, but still no display, bought a new GPU, still no display, removed and replaced ram in different set up's, still no display, is my motherboard somehow fried?

did not resolve the problem it's a dead pc. Any help please?

I would start by checking every component. If you have spares - try using those to eliminate components as the cause. Use the onboard video card if you have one... If the problem still exists, it is likely not your video card.

One of the most likely causes is RAM. Try reseating all of your ram modules. There is a good chance this is the culprit.

i had the same problem.......try changing you RAM....worked for me !!!

i think its the graphics card

This is a common fault when certain additional graphics cards are used.
2 options. 1) remove add on graphics card and boot with onboard card. OR
2) inbios check that you have enabled support for any addon cards.

When i had this problem i needed to get a new motherboard. That fixed it right up

jomar- May 2, 2010 09:05PM
i tried everything ive change power supply, memory ram, video card, only the processor i did did not replace/or test in anohter mother board or your right may be i need a new motherboard.
akram- Nov 3, 2012 12:35AM
go and replace ur motherboard that the perfect solution

check the cable of your monitor and if nothing happens then check your video card. If again when you open the power of your pc and still the same, you can try to change your video card or again if nothing happens then you should buy another computer coz your pc is dead.....

it can sometimes mean the graphics card has fried, my computer did it, grahpics card didnt help, neither did it when it happened to gfs computer but when it happened to my managing directors, it fixed it... just my luck

I posted number 17 on here I forgot to ask... what the heck else could be the problem? I mean I used lower rated equipment to ensure the psu wasn't being drained, the mobo seems okay as the ram test is carried out normally... what should i do?

tipscomputer- Oct 1, 2009 09:07AM
then check you monitor. if all are working. then sorry i cant say the reason, but do onething to check the SMPS. if it gives +0.4v or -0.4v variation from actuat means, showing 11.6 or 12.4 instead of 12v , so on. then its good to change it. check all the particular pins of smps and read the voltage. it must me intact. if its okay then try to change all the data cables.
