Im also having that exact problem with my GeForce 7300 GS and I have that same power suply too, the coloursIT 12volts @ 30amps 400w. Damn thing crashes all the time on games (san andreas etc.) I dont really know a lot about this sort of thing though, found this thread from google. I was thinking it was my graphics card because it doesnt reset with it out (but its crap and most games dont work) , but after seeing this im thinking its the psu, have you fixed the problem? If so how'd you do it? :grin:
