I just purchased the MSI GTX 660 replacing SLI'd GTX 260's in my system, however upon starting my computer there is no signal on the monitor...the graphics card will not display although the fans on the video card both work.
I've tried different monitors and switched back between my old cards and they work, but the GTX 660 will not. I have never flashed/upgraded a bios before although I heard that might be a possibility? I already tried uninstalling my old drivers and that didn't work. I installed it in my buddies system and it worked!...so I tried checking his PSU thinking it must be the power but couldn't find any specs on his PSU...it's all black nothing I could find.
Here's my system with the MIS GTX 660
Core i5 750
EVGA P55 micro LGA 1155
MSI GTX 660
Kingston 8 Gigs PC12800
1 TB HD
850 watt rosewill PSU, 4 12v rails @ 20 amps each (the MSI card requires 24 amps...is this the problem?)
