My computer shuts down at startup of games

[christoffellis]

As the title says, it shuts down, like the computer goes off. It happens with games like planetside 2 and Ghost Recon Phantoms, but games like Minecraft have never made the computer shut down.

I have contacted Planet Side's user support, but they only gave me a temporary solution. They asked me for a file which contained my installed programs. Their solution was to disable McAfee antivirus, it worked once but not again. Could you please help, and if you need any files, just ask.

My OS is windows 7

My computer is about 1 year old and I don't know how to test any of the three requested, sorry

if that is the fix they gave you,you do know that you have to disable mcafee every time you play that game?i would get rid of mcafee and download avast antivirus free version.

I did uninstall McAfee, no results. They told me to disable my antivirus from startup, which worked for like 2 days, then it no longer worked. I use Kaspersky
