Computer Shuts Down! OVERHEATING??

March 2, 2006 at 18:06:47
Specs: XP sp2, p4 2.4 / 640mb ddr266(pc2

Hey. Ok my computer has been suddenly shutting down recently. it happens mostly when running i guess "intense" processes for a little while, like playing games for a while, or using pro audio production software, etc..

When it happens you cant start it back up right away. you have to wait a while and even mess with the voltage switch and stuff on the PSU (after you wait a while i can switch it to the wrong voltage and turn it on for just a moment, then i cut the power and start it up again on the right voltage and it works).

ok. I am quite CERTAIN it is an overheating issue. I switched out the power supply for a brand new one. Still have problems.

BUT... the problem seems to be gone when i take both the sides of the case off, and stick a huge ROOM fan beside it...

but please understand i cant have my computer open with a room fan beside it forever....

i did install two extra internal fans. guess they just arent enough.

i really dont know what it could be!

i even changed out the fan on my CPU for a fresh one!

anyone have any ideas??????????
what (likely overheating) in there could cause these symptoms???
the whole system just cuts power and goes dead till i pull all that shiz i mentioned to get it back on.

please help!
thanks

Did you balance the fans so that you have equal fans blowing in as blowing out. The power supply fan is one of the blowing out.Ideally it would have two fans in the front bottom blowing in and two fans in the rear top half blowing out.

Sorry, I do not check for private messages

You are an accident waiting to happen. Do you do this with the new power supply as well that you tried?

well first off, no i didn't even think of that fan balancing thing.
but even so, the new power supply like the old one only has one fan. as for the other two case fans i installed, they are so weak and far apart i doubt it will make a difference but i'll make sure ones blowing out.

and GX1 Man yes i did it with both power supplies, because the computer shut down with both of them. and with both of them it was the only way i could find to boot the computer back up.

there must be a shot component inside allowing it to overheat too easily... to the point where when that component cuts out, it causes the whole system to cut off.

i dunno, perhaps a hard drive??? RAM?? or maybe a shot motherboard??? i dunno, hardware experts look at the symptoms and diagnose my problem!! help!!!
thanks for input so far

Hi,

I'm wondering if you have applied any thermal paste to the CPU die/heatsink, without it your CPU will give out pretty soon..
It could also be the ram as emuse says..
And you really, really don't want to muck about with the voltage switch on you PSUs...stick to whatever it was originally set to...

Using a bit of care, lightly touch the heatsink after the machine has been running for awhile, making sure you have no static electricity build-up, and be aware of the fans and other things - like cabling etc..

Does it feel extremely hot? I don't mean warm, I mean just too hot to touch for more than a few seconds or so...if so, your CPU is not being properly cooled...

You may need to invest in another heatsink/fan unit..

Good luck...

yes i did apply the thermal paste. im not sure the fan and heatsink are the problem. first because i switched the old fan for a new one when the problems started. the new fan is supposed to handle like a 3ghz cpu and mine is only 2.4
plus i remember checking the cpu temp around that time and tho it wasnt really low it should have been within limits definately nothing extreme.
could the RAM have anything to do with it like the other guy suggested? i'd like a second opinion before i go buy some
