Hello, i got a MSI Neo4 Platinum motherboard, AMD Athalon X64 3200, 3GB of RAM, and I just slapped in an XFX GeForce 8800 GT Alpha Dog to replace my old ATI X1600 [since I broke a capacitor taking it out on accident]. I'm getting a black screen at boot, no nothin anywhere. I reset the Cmos by removing the battery, and even restarted in safe mode with an old pci graphics card to use a driver cleaner to make sure nothing was in the way. No dice. Any suggestions? Running Windows 7.
