Desktop Computer keeps rebooting after being dropped.

June 2, 2013 at 15:57:50
Specs: Windows 7
I was moving my desktop computer the other day and I dropped it. At first it wouldn't turn on, so I opened it up and a plug was loose so I plugged it back in and it started up fine. I didn't see any visible damage to the internal components like the gpu or the mbo. But my problem is that when I start playing a game after about an hour it will reboot. If I start it up and continue it will do it again but in a shorter amount of time.

Are the fans all still running? This sounds like an overheating issue.

Yes all fans are running, except the power supply which i think only turns on when needed.

It only happens when you're playing games? That's usually cpu-intensive so heat may be the problem even thoiugh temp is not all that high. As a matter of fact 31 C seens kinda low. Maybe a problem with the sensor?

If you dropped the PC with enough force to knock loose a plug I think a lot more damage would have been done. Maybe it was loose to begin with. You may want to verify the metal contacts aren't flared out and not making a good connection.

It seems if I play games on a lower graphics setting nothing happens. Would that be the gpu overheating?

If i were u i will re-connect all the components (cables, v-card & Ram) and check the heatsinks (both chipset, mosfets, v-card and CPU) if they are OK.

I don't know if an overheated gpu would cause a reboot but yeah, that'd be an obvious thing to check. Are you using on-board video or have you added a card?

I guess it's got a fan on it then? How's it spinning? A lot of those video card cooling fans are low quality and after awhile may slow down or lock up completely.

It has 2 fans. They spin fine. I'm going to reseat the gpu and get back with you guys.

"all fans are running, except the power supply"

That's a good clue. The power supply fan should always be running.

I suspect that when you're playing games, the system is drawing more current and the power supply is having trouble maintaining stable power output. Power fluctuations are a common cause of random reboots.

The power supply fan does spin when first power the machine on just not any time after. Not sure if it gets hot enough. But i reseated the gpu and rechecked the plugs. I will let you know if it happens anymore. Thanks alot.

"The power supply fan does spin when first power the machine on just not any time after."

That is a major problem! The 2 most important fans in a computer are the CPU and power supply fans. Both of them should be running 100% of the time, with NO exceptions.

I have seen PSU's where the fan is designed to come on only when it gets hot. I never thought that was a good idea but if his is one of those then it may be working properly. Still, it wouldn't hurt to swap in another PSU and see if the problem persists.
