I've got a windows xp professional computer, built and installed everything myself.
Recently my pc has been rebooting itself when I'm doing something. It used to be just when I was playing eve-online but only when I actually went into a mission with loads of other bad guys around.
I thought windows was corrupted anyway so I bought xp professional.
Unfortunately now it's rebooting itself whenever I try to install world of warcraft (Or play eve online). I should note that I've installed it previously without any problems. It lets me get to disk 2 sometimes and then just turns off, it doesn't shut down, it's just like someone flicks the power switch off and then it turns itself on.
So we know it's not a problem with windows.
Could it be a harddrive problem? I'll try installing other games and giving them a whirl and see if it gives them problems as well. It's allowed me to install other programs though, I image it's because of wow's size. The harddrive is about 3 years old ish.
Or is it likely to be a faulty power supply? It's not even a year old.
It's a Corsair 520W HX Series Modular PSU - ATX12V v2.2 APFC $140 roughly
Or would I need to flash the motherboard with the latest update?
How can I test what the problem is? And what further information can I provide to get the best possible answer?
