I've recently acquired a free Voodoo 4 4500 AGP card from a co-worker. Last night I was finally able to get around to testing the card, and ran into a couple of problems in the process.
First, the problem is noticeable at the Win2k splash screen, and after Windows loads. Secondly, using the generic VGA driver provided by Microsoft I am able to boot into Windows. HOWEVER, when I install the 3dfx V4 4500 drivers, the system will hard-lock when reaching the log-in screen. As you can see in the pictures, there is no banding in the WinBIOS interface, but the bands appear in Windows, and the black / white garbled screen only appears when using the official 3dfx drivers.
Any ideas? I suspect there is either a bad solder joint or bad RAM chip somewhere on the PCB?
