Computer turning itself off under weird circumstances

Hello, I've been having some computer troubles for a while now, recently replaced all my HDD's with 1 new one which took care of 1 thing, but my computer is still behaving erratically.

Currently what it does is if I leave it alone for 5 minutes, the screen goes black for 1 second and then the computer turns off, and when I turn it back on, it doesn't give me any error messages or anything, it just turns on like nothing happened.

The weird part is, it only does this if I have certain games running. Recently installed windows on the new HDD, so don't have a lot of games on it yet, but it only does this if I have Star Wars: The Old Republic on the character selection screen and with World of Warcraft on the login screen and the character selection screen. It doesn't turn itself off if I log on to a character in those games and then go afk, nor does it do anything if I just play or just leave it on the desktop or anything. I ran a performance test on the whole PC with Passmark and it said everything was performing as it should.

Though I did have the PC looked at in a shop, where they said the video card and the HDD's (which I now replaced) are dying, but everything else was fine.


Another problem I'm having is rarely while playing a game, I get half a second long screen freezes during which something makes a sound inside the computer, can't really tell what and then the freeze ends.

Anyone have any ideas?

Speccs:
CPU: Intel Core Quad Q8200
Video Card: ASUS Radeon HD 4850
HDD: WD Green WD20EZRX
Motherboard: GIGABYTE GA-EP43-DS3
PSU: Black Diamond BD500W

Looks like it's the power settings in windows that sre set for the computer to sleep in very short time. To change it goto Control Panel - Hardware and Sound - Power Options.

About the other problem I have no idea

It isn't though, I have it set to "never" and it isn't going into sleep mode, it's turning itself off. And it also only happens if I have any of those 2 games open on login screen/character selection screen.

I've updated the post with the specs and I've tried reinstalling the driver, but it stays the same, still turns off, but still only with those 2 games.
