ok, a month ago i upgraded my graphics card. went from dual hd 4850s in crossfire to a single hd 6870 dual fan by xfx.
about a week and a half ago my computer stops turning on. it makes it to the windows loading screen, or sometimes the motherboard screen before that and then shuts off.
i thought it was a power supply issue, so i bought a new one. long story short, i'm RMAing that back to newegg cuz its DOA, so i buy a new one from best buy tonight. its a 700watt corsair GS700.
my computer is still turning on and shutting right back off like it was. no change. if its not a power supply issue, i'm not sure where to go next
