I recently re-seated my video card after doing some wire management. When I turned the computer on, the 3 red lights on the 4870 flashed 3 times and there was no signal input, but the three green lights and spinning fan suggest that it is functioning properly. Same result in the other PCI-E 2.0 x16 slot. I did pull the graphics card out when the motherboard light was on (computer off), but I thought the power supply circuit needs to be closed in order to ground myself. I want to RMA the video card, but I'm hesitant it might be some other problem that I'm overlooking (or even worse, a bad motherboard but good video card).
I know it POSTed and booted Windows 7 by using Logmein, a remote desktop control utility, from my laptop. In Logmein, there are artifacts such as incorrect colors and graphics not even showing up, like the minimize/expand/exit buttons (this doesn't happen when using Logmein through HD3300). Windows has forced the resolution at 640x480 and CCC says that either the drivers have failed or I don't have an ATI video card installed. Rivatuner doesn't detect the video card anymore. Device manager says that the device has malfunctioned, but at least detects it as a 4800 series video card. How did it POST? No signal input on monitor connected to computer.
If the computer booted into windows (although there's no signal input to monitor and a load of errors), does that mean the video card is fine, but maybe there is a problem with my motherboard? What else can I do to troubleshoot? I'm going to run memtest86+ overnight if that helps and take everything apart and connect only the bare essentials.
