My PC Restarts when...

[Oisterman]

I'd physically touch around your PC and check the temps. My laptop was doing that, but then I found out its because my fan wasn't working. I know you said you checked the temps, but it can't hurt to double check.

Download HWMonitor and post a screenshot here, both idle and under load.

Before doing under load, do this. This will prevent an autorestart when getting a BSOD, which is also plausible.

Thats nonsense, 500W is enough for your pc, sure 100 Watt extra might boost your pc a little but if you havent enough watt your pc wont restart itself. This sounds like an overheating problem, this can either be the graphicscard or just bad cooling in your computer. This can also be a PSU problem but by the sounds of it I am betting the cooling. Try cleaning your computer from the inside dust etc, close all the programs you dont need to be running and test again. Have a program running checking the temperature in your computer and please report back



Nope it cannot



Im pretty sure your computer case has fans as well, but if you havent had any problems before it is most likely an overheating problem. So check if all fans is running while your computer is on. Updating drivers might help as well, sometimes theres a bug in the driver that lets the cooling fck up. I have no idea if the ATI drivers support turning your fan speed higher but on default its on 60% speed, you can try turning it up to 100%

well i just give him option what will cause the problem but most time it overheating

Sure does sound like overheating. I've had this problem as well and it was my gfx card getting really hot and eventually it fried taking the mobo with it.

Same symptoms as you, random restarts. I could play some games all day and some games for an hour or so (depending on graphics) and sometimes it would restart when I was just browsing.

Just do what Snow said. His psu got nothing to do with it, and it's probably not the GPU either. The only thing I can come up with is reinstalling the driver or updating it. If you get a 750watt power supply, while you could easily pass with a 450watt psu, the only thing it boosts is your electricity bills... A psu is just what the name tells you, it supply's power to the components in your computer.

Depends if he had his rig running properly before, this sounds indeed like ****ed up drivers but could be an overheating problem as well. I am curious for the results...

Thats not an option because if you have a monsters computer with lets say a 300W PSU your rig will run just fine but will be bottlenecked. It will never restart because of this

What's your motherboard? I had an issue in the past where my computer would randomly restart while watching videos online and sometimes while gaming and it was just a stupid freaking energy saving feature on my motherboard, wasn't necessary just some gimmicky "green" feature that I disabled and viola problems gone.

[I.D.]

If your computer is randomly shutting down without a blue screen it could be hardware failure.

I had that problem and over time it would shutdown quicker until my computer could not even get to the desktop screen before shutting down.

It turned out it was my motherboard and once I replaced that I never had the problem again.

Okay I checked all my drivers with Driver Update program and all of them are up to date and none are corrupted.

I disabled auto restart, so when I get the error I'll read it and see what it says. Will test Deus Ex now.

Well this doesn't work...was playing Deus Ex: HR again and it shut down and wouldn't bring up an error.

So this leaves me to...My graphics card overheating...I think I might put a fan next to it near the back.

I can't recall that the 4xxx series had overheating problems. The closest I can find a link to would be the GeForce 4xx series, which were more a microwave than a GPU.

hmm alright, well I do now somewhere around those series the temperatures were WAAAAY higher than before
