I just built my new computer.
I bought Geforce gtx 570 ti FARSA graphic card wich keep on crashing down in a random amount of time...
the screen says "no signal". its really driving me crazy. when I try to change my background picture it crashes back to "no signal". its up to date.
Can't find anything about that PSU, which means it's probably a cheap, no-name unit. NVidia recommend a 550W PSU for that card. Probably not strictly necessary if you have a top-notch PSU from someone like Corsair.
