I should add this:

Diablo comes with a vid test mode to set the game up.

It tests direct draw the direct 3d

From a cold start it works fine... up until direct 3d. Blue screen.

Shut it off again. Start up. CHeck outlook. Load AO. close everything. Load Diblo Vid test, get to direct 3d. Bam.

Restart. Load Diablo. By pass vid test and Initialize game. Go through menues until the game world is initialized and Bam

OK. Restart again. Send error report of system recovery to MS again....

Turn vid card down to lowest resolution load vid test. Direct 3d runs a little longer and doesn't bam right on direct 3d test but eventually .... bam

Error report again

Keep desktop at low res. Load diablo, bypassing vid test and it plays. For a while, I am hacking skeletons then hit esc by accident... BAM.

load again on putting windows back to high res. BAM

Back to low res, game works fine but sometimes changing a map or going through a portal BAMs that card. This time I have even hit esc a few times and got back in.

I have played this games on lower end systems with not as much memory or vid memory. Perplexed. I want to think either the vid is overheating or running out of memory in the 3d part but I just don't know. Are there any good 3d testers out there?

Trying the leave off for a while mechanism.
