I tried searching for something similar to this; if it's in here, I apologize and would appreciate a link.
My NVIDIA 8800GT bit the dust. I have an old GIGABYTE GA-K8N Pro-SLI mobo. I replaced the 6600 with an ATI HD 5750 from Sapphire.
Or at least I tried to. The card fan spins and lights go green but the computer monitor never budges out of standby.
Using the crippled NVIDIA I can load windows in about a 640x?, 4 color res. I used that to install the latest ATI drivers. But I never pass go. The monitor still doesn't respond. I don't have onboard video, so I don't have an alternative to diagnose what's happening.
I have a ridiculous PSU (550W) so I don't think that's the problem. What am I missing? I've Googled around on the problem and see things that are close, but not my issue.
Appreciate any help from the ATI fans in here. I had high hopes for finally fixing this desktop this evening.
