My PC Restarts When I Open or Play any PC Game

[Danboi2]

Hi everyone, I'm looking for a bit of help. Whenever I open any game for example pc just reboots or if the game does start it starts to load say the videos before the gameplay and then same it reboots.

My PC is raised off the ground
I have Windows 7 64 bit
- Processor: Intel Core i5-2500k CPU @ 3.30GHz 3.30GHz
- Antec 750w power supply
- Msi motherboard p67a-gd53b3 with latest drivers
- 8GB Crucial Ballistix memory
- Sk hynix 128gb ssd with only the operating system on
- Fractual design r3 case
- Be quiet Dark rock pro cpu fan
- Nvidia 770oc 4gb with latest drivers
- I have also tried 2 other cards and the same thing seems to happen

Tested with prime95 blend and even thou the temp rise the pc stays on temps go upto 50c on core temp program

Tested furmark 1080 and 720 and there doesn't seem to be any consistency sometimes you click on the test and it works and other times it reboots straight away

Thank you to whoever reads and replies :~)

Hi, Try testing different power supply, if possible, or RMA yours.

I'd start by making sure you have the latest video drivers, then check your HDD for errors and fix if you can (run chkdsk).

This might also be a symptom of your vid card in its death throws. Perhaps if you can find a spare card to test with and see if the problem goes away?

Finally, it could be an issue with your power supply.... not sure how to test for that though.

Good Luck!
