i have been trying for over 3 hours to get this to work using the few suggestions i have been able to find but so far i still get no video from my new 5770. i press the power and everything starts working, the fans on the cpu, case, and videocard but i get to video signal.
i have set it in the mobo multiple times, i have checked and rechecked all power plugs and connectors, i have tried on 3 different monitors, my onboard video and current videocard(7600nvidia) still work fine.
i am trying anything i can before returning it for a new one incase something is wrong on my end. i am thinking my mobo might not be able to handle the higher end card but it should still work from what other forums have said, just not as well as it can.
4x1 gigs of kingston ram ddr2 pc2-5300 333mhz
C2SBA supermicro mobo (1.2a bios, which is up to date)
intel core 2 duo E8400 3.0ghz
7600gt nvidia geforce 256ram(current)
yes i used both 6pins to make sure one isnt issue.
no, it seems like it is booting up. HD clicks and throttles, fans run and mobo lights work. i sounds the same as when it boots into windows with my current videocard.
yes. hdmi to hdmi. hdmi to dvi. vga to dvi(using a vga to dvi converter). i unplugged my monitor in between trying all of these as some forum said that may help, it didnt help me. i also used a 2nd monitor, vga to dvi(using a vga to dvi converter) and that didnt work.
yes. as i stated above, it does seem to boot into windows.
One other thing you might try is boot using the onboard and delete all of the Nvidia GPU drivers then switch it back to using the generic VGA driver - put in the 5770 and try booting again(could be a driver conflict in windows if it is trying to load the Nvidia drivers instead of autodetecting the ATI card --- I know my 5770 gets autodetected as an old Nvidia FX57xx series card on a couple of older games by mistake so it could be that windows thinks it is a NVIDIA card and is trying to load the Nvidia video driver instead of seeing it as a new card and installing the ATI drivers !!)
