Here are my specs: Asus striker 2 extreme E8500 3.16 Ghz BFG's gtx280 ocx 2gb Ram Crucial 2000mhz ultra x3 1000watt PSU Windows xp, sp3 I'm a first time builder. Please be gentle. I try playing games, but my computer just shuts off. To be more specific, when I play ut3 at 800x600 with all the setting on low. My computer turns off, the monitors go black. I wait for a few seconds to see if my monitor shows something, but it's just black. So I turn the power back on the computer and everything turns on ok. Or so it seems.... I have tried playing games on the lowest setting possible and it works... but it's all blurry... so it's no fun. Here's what I've tried. I unchecked the "automatic restart" option, but even with that it still turns off with no info on why it turned off. I've checked to see if the CPU and Graphics card run at normal temps. They do. I've updated everything I can think of. I've read other threads on the same problem but still don't know what's up with this. I've ran memtest already, it's all good there... Any help would be greatly appreciated. On a side note. I installed windows xp at my friends house, did the windows updates there, then brought it to my house, would that matter at all? Thank you for taking the time to read this.
