Computer Shuts Down - Why? Unknown Cause...so stumped

[Grafitti 0]

So I switched the fan around to blow air out from the back. my case doesn't have a filter in front. should i exchange it for one that does? i don't understand why a branded case (fujitsu-siemens, in my case) would omit a pretty necessary air vent.i'm working on the Intel monitor utility, but i have noticed that the processor fan runs crazy when the heavy-duty stuff is running. So does that mean it's my processor that is the cause of the problem?

nope, fan speed should go up when the cpu temperature rises.
About the GPU temperature, could you stress the vid card (rthdribl -> http://forums.xisto.com/no_longer_exists/) and then check in the nVidia drivers how hot the GPU is ?

And other thing you might check is the memory, since video-editting and gaming is pretty memory intensive. You could use memtest68 for it (can't be run in windows, (that's the good part because every block of the memory is tested) but you can make a bootable floppy)

Solved the problem. stuck a regular fan in the side of my desk, and got a dual fan cooler for the hard disk. Still it's not the best because of dirty power, and i can't get higher rating than what i have now. it's almost impossible to find them here. But it works ok at least, though it's a rough job.

If you want really good cooling, Go to http://www.frozencpu.com/, They have alot of new cooling tech that can get your computer to an almost perfect tempurature.

So, actualy the problem isn't realy solved, right ?There still is one thing that bother me, why can you play at 640*480 but not at a higher resolution ???I realy don't know . Try some programs that can stress your cpu (prime95), memory(prime95/memtest68) or vid. card (rthdribl).And than there is another strange thing I noticed. There is some kind of foam behind your motherboard (right behind the cpu). No clue what it's doing there.

[Killer008r 0]

That foam stuff is actually really good insulation. You should keep it there, Also it stops any dust getting in the back. I would say keep that there.

well see I don't know what the foam is there for, it was there when i bought the computer. see here it's not so easy to just buy single pieces. i could have, and i was going to go for an asus motherboard, starting with that and hand-picking components for the computer, but here the service and warranty is super bad if you use anything that's not widely used, so with all the power outages and whatnot i couldn't afford to risk it (i've already had 3 power supplies and one regulator blow out), so i'm stuck with the piece of junk, to put it nicely. So anyways i figure leaving the foam there can't hurt. i can play at the lower resolution longer, i guess because it doesn't tax the cpu as much. if i were to put it at 1024x768 and high detail i could probably get through about 5 minutes. as it is, i can sometimes go up to almost half an hour before i hear the fan getting too loud and i quickly have to exit before the computer shuts down. by the way, I called the company and they gave me the original install cd for the motherboard, -which they hadn't done in the beginning -, and i found a motherboard and hardware monitor from intel on it. So i installed it, and it keeps telling me my cpu is over temperature. it get to about 72 C. that seems pretty hot to me. and it gets like that, all i'm doing right now is running acronis backup, outlook express, and firefox. it's at a whopping 75 C. like HELLO??? and their service tech told me it's normal. he ALSO said they don't recommend using the intel monitoring utility because it's inaccurate. Inaccurate my a$$. How come then my computer shuts down?

hi,, just today i cleaned my CPU fan and cleaned HotSink.. and after that my pc wont start.. fans run in normal speed.. but not high speed (generally in startup for first 2 sec it run slow speed.. than run on high speed) and even my screen is not getting any ... like not attachend with my pc..something wrong i did during cleanup..????????i cheaked all connection it good.. and as it is like before..pls help with this.... my emil is bbpatelca@hotmail.comthanks for your helps

I tried the motherboard monitor. it doesn't support the 915 board from intel. --at least it didn't seem to find it. it won't give me any temperatures. all it gives on the sys report is this:

here are the pics of the inside:

this one is a view of the whole thing
the next is a close-up of the graphics card and nearby

so altogether it has two fans. one in the rear, and one over the cpu. there's no place to put one in the front. The rear fan sucks air from outside, and the cpu fan spits air out. Let me know if more detailed pix are needed.
