So lately my comp has been shutting off and rebooting itself for no apparent reason at first i thought it was overheating cause one of the fans would spin up really quick and load for like 5-10 secs and then the comp would shut off so i took it apart cleaned and that worked for like a week or so and now its started again and i dont know what to make of it. i appreciate any advice and or input.

I had a similar problem before and replacing the power supply helped for a few months. Afterwards, the problem came back and the computer technician advised that a lot of other issues may have caused it such as defective RAM or motherboard problems... I just bought a new PC in the end. heh

Download and install Speedfan. It'll show you how much heat your PC is actually generating by monitoring the temperature on the board using the onboard sensors. Over 60 degrees is trouble for your board, and some boards can sense that anything over that limit will shut themselves down.

By the way, Keeper, what's your system specs? How old is it?

You should look how are the capacitor on your motherboard, one of the first sign of bad capacitor is reboot without reason.

In this page http://en.wikipedia.org/wiki/Capacitor_plague you would have images of capacitor gone bad.

its a gateway gt5628 which includes qq6600 quad core 3 gigs of ram 500gig hard drive and a geforce 8500gt gpu and when i opened it up the other night and was looking around i noticed that the powersupply is a wopping 150 watts max

its close to 2 years old

it might be old and that's why it's rebooting itself, check if it has any viruses

Do you still have warranty? I suggest calling them so they can repair your computer.

It's most likely a power supply/motherboard problem. Check the capacitors first. If they aren't damaged, then it's most likely your PSU... In that case, you need to get a PSU that is compatible.

Whoa. You sure it's 150 watts? Or 400 watts as Claies points the specs out at the Gateway site?

A PSU that low isn't gonna give all the juice such mad specs would need. Since it's a Gateway box, see if there's a better aftermarket PSU with at least 500 watts that could fit right in the power supply bay.

Gotta have some power consumption recalculated before buying:

Check the board instead for bad capacitors.

No, it better not be 150W. It's 400W.

I'd check the temperature again, if not the PSU. The overheating could have knocked out a capacitor or other parts of the PSU.

in my old laptop I had problem with the windows rebooting and/or shutting off at random times, it was the memory, and I needed to change it.

Question: No blue screen of death? Were you there when it suddenly restarts? I believe XP and Vista reboot immediately at a blue screen by default.
