Auto restart when playing games

[digimonkk]

hello sir, you got a very intrested page,
and i think you can answer my question,
i got a pc with dual core 3.0Mhz LGA775, 4GB ram, on a windows 7 pro 64bit, service pack 1, and im using a 500W Psu
and i just bought a gtx 760, but i cant play any games with full graphic, my pc will auto restart and sometimes it show a blue screen error code 1033, or power surge error at the post startup,
i really appreciate if you can tell what is the problem with my PC

What make and model is the PSU?  I would suspect it's at fault here.

PSU is colorsic 500w.. not branded PSU..

I'm not too sure since I've never had that problem but it sounds like it could be an overheating problem. Check your GPU and CPU temp using SpeedFan or RealTemp. GPU's should go from 60c to 90-100c under heavy conditions and CPU's should go from 30c to 60c. In the worst case scenario it could be your PSU going bad but it's unlikely.

I would agree with Calum here. Problems like that are commonly PSU issues. Per this:

You're already running at the minimum recommended. If you have a system with several HDDs or a bunch of fans, that could easily put you over wattage. Also, if it is not a good quality PSU, then it may not being supplying full wattage as needed. This could also be the case. It could also be a driver issue. It is always important to stay fully up to date with your drivers. So I'd certainly recommend that. Drivers are free, so if you're lucky it is a driver issue.

In the worst case scenario it could be your PSU going bad but it's unlikely.

As a note, PSU fault is the most common problem I've come across in all my dealings with computers. Second was GPU problems. Keep in mind that all the electricity that a computer uses is managed by the PSU, so it is the first point that will get hit with power surges, blackouts or basically anything electrical. It's also usually the only component that deals with raw voltage and amperage, which means it get's hit hardest.

Check the drivers and see if nVidia supplies any new ones, then if that doesn't result in a fix, try swapping a better PSU in there (I'd get a 600W just to be safe). If that doesn't work, we'll still be here!

Never heard of that PSU...not sure i want to.

I suspect the PSU is at fault, as said previously, especially considering it's a no-name budget unit.  Even if it's not causing this issue, replacing it ASAP with a good unit would be a good idea, before it causes other problems.
