My son has a Dell desktop that's a little over a year old. Periodically (he says only when he's gaming) it'll shut down on him.

We opened the case and blew out what little dust was in there. Both fans are working. I removed and re-seated all of the RAM, since I read that could be the problem. He says he has all of the latest drivers installed.

He ran a temperature check program and got 62C on the processor after a re-boot, which supposedly isn't unreasonable.

He tried running it with the side of the case off, and still got a re-boot.

Short of shotgunning it and replacing the power supply, does anyone have any thoughts on what could be happening or suggestions to troubleshoot?

Can you monitor the video card temperature?

First thing I'd try is turning down the in game graphics to low and see if that improves the amount of time before it shuts down.

when that happened to me several years ago playing call of duty, it was a bad video card. replaced card, all was good.  



it also could be a bad power supply.  i would test that by putting the system under a non video intensive load such as calculation pi to a bazillion places.  if it crashes doing that it is probably the PSU, if not then it is likely the GPU.

Could be power supply is inefficient for his system.

That'd be my guess too.

Mine as well, but you would think that with a pre-made.....

Nah, it's Dell.

I'll check the rating on the PS and try the non-graphics intensive calculations to see if that helps narrow it down.

Thanks guys!

I'll check and see if he has an application for that. I don't have any thermocouples at home to do it directly. I'll also have him crank down the resolution. I know he's got it pretty high.

is it the original video card?

62C right after a reboot?
that seems high to me

even with my quad core hitting 100% on all 4 cores for a while I usually don't get that hot

If no hardware has been added the PS should still be good but they don't give you a lot of PS headroom in those systems.

First thing would be to check the event logs, if that isn't telling you anything then update chipset, video and lan drivers.

It wouldn't hurt to do a chkdsk /f just in case and finaly some kind of memory test

If a memetest comes up empty you just might have a bad supply

No hardware has been added or changed since new. He popped the top today and we found out that it only had a 350W power supply in it. Not exactly a lot for a quad core i7.

Updated all his drivers and Windows again. Tried lowering the graphics settings. Still the same crash. According to him, he now thinks it only crashes on two of his FPS games. I thought it had crashed on other programs as well, but he says no.

Did some more internet digging and found that people have replaced the PS on that system with a 650W supply. So, off to Newegg I went and ordered the same replacement as they had been recommending. Should be here in a few days and we'll see what happens then.

Shut down HOW?  Shut down in a blue screen?  Shut down as if someone unexpectedly cut the power?

If a random, intermittent shutdown, try the simple thing first...the power button wires in desktops can become loose.  That is your first culprit––especially since  you seem to have checked everything else.   Hopefully the new power supply solves the problem, but hopefully not (so you can return it if the problem WAS the switch..).

Shuts down as in shuts down as if somebody cut the power. No blue screen of death.

I'll check out the wires, but I figured the PS was a no risk option since we plan on building another system sometime this summer anyway. If I don't need it for his, I'll just use it for that.

yeah if i was you i would dump that 350 powersupply fast and get a bigger one like you said. im sure the shutting down is being caused by it.
