My computer keeps rebooting after it has loaded onto Windows if I try using chrome it will load but the computer will reboot as soon as I started loading web pages. And then won't even load Windows after it had rebooted I just have to leave my computer off until the next day. It's a new computer I built in December last year and the problems started about 3-4 months ago it started of that it would only reboot when playing games then got worse and at one point I had to restrict my cpu to 50% and it would work fine but I have replace the thermal compound that didn't do to much difference only when I first did it. I sent my power supply back to were I got it they ran test and said that it was fine. Any ideas on what the problem is would be nice thanks.
