.. 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
thank you, and goodnight
