Card dead. Interesting observations.
Well, somewhere in the last week (don't know exactly when, wasn't at home), my videocard (Geforce 7900GT) died.
Most likely one or more of the memory chips have gone bad.
Symptoms: During boot (BIOS mode), random characters on the screen are wrong and in strange colours.
Once Windows (2k) boots, during the splash screens there's odd-coloured splashes of colours, and then updating stops pretty much completely. Big changes sometimes temporarily affect small parts of the screen, but that's it.
Funny thing is, once the Windows drivers are loaded and the card switches to dual view mode (I've got two screens attached to the card, plus a third to another card), the problem is limited to the primary screen. The second screen attached to the card works fine.
This leads me to conclude that in dual-view mode, the Nvidia drivers put a hard divide in the memory, allocating half to each screen. The bad chip(s) ends up allocated to the primary screen, and I'm limited to using the other two for all practical purposes. haven't tried gaming on it yet. I expect BSOD's galore...
Technology aside, the sudden death is kinda annoying, as was planning an upgrade, but was waiting till Ati/AMD's HD5xxx launch later this month, either to get a newer model, or for prices to drop on the 4xxx series.
Luckily, I'm hardly at home at the moment, so I'm not really in a rush.
