System shutting down and rebooting

[moondawg009]

For some reason when I'm playing the Witcher 2, my computer will randomly shut down and restart. My GPU is a GTX 770 and it never goes above 60c, and my CPU i-5 3750k never goes above 60c either my computer never feels particularly hot, could it be a weak power supply I currently use a 650w.

Why would it be just during that game?

I run other much more graphically demanding games just fine, any suggestions?

What PSU did you get?
A cheap PSU will not be able to put out the power ratings it talks about.
Most cheap PSUs will say 650 watt, but will not get close to that.
You GPU says is needs at least a 600 watt PSU.

I would recommend a 700 watt+ PSU.
Your system is power starved. Get a good band PSU like EVGA or Corsair.

Your GPU or CPU is hitting a high point and crashing the computer because there is not enough power.

Your CPU is 77 watt and your GPU is 230 watt. !!!!!
That is 307 watts just for your CPU and GPU.
A bad cheap PSU will not be able to handle this and your system will start crashing.
When you get another PSU make sure you get one with at least a +12v rail with at least 50+ amps.
That will give you 600 watts on the +12 rail. 12x50=600.
Amps are important. Very! A PSU can say 600 watts but only have a 20 amp +12 rail. (Only 240 watts on the +12v)
Happy Computing!

I have been using this PSU for about 6 months and it only started happening, is it just becoming worn out?

Most likely. The PSU is failing and can not keep up with your system.

Unbranded PSUs are a bad idea. They can damage your system.
I would highly recommenced a PSU upgraded.
I have to upgraded mine. It a cheap one like yours and can not handle my system.

Get a 850watt PSU, what wattage is your PSU? Seems like a 400watt stock PSU (Keep above 600 and you will be fine) Recommend AXi 850Watt PSU from Corsair they are amazing for efficiency! and for along term builds 5+ years before it starts getting old and/or dies
