Cannot play my old favorite game Diablo II after setup and test for functionality says Iam golden. What happens is as I start the game my monitor tries to bring up the game and I snap back immediately into my desktop.My system is a ASUS Black Pearl(CUSL2-C) 815EP chipset/Intel 1G/512Ram/I Panel/Live Drive/Zip/ Here is what I have done. PCI slots "not sharring/Current Bios/Current ATI drivers/No IRQ problems/Tried all monitor freq rates/Latest DirecX/Check visual AGP slot/Checked arpeture in Bios-(64)/PHEW!! Kicker is if I throw in an old Viper 550 Or 770 No problems. Also I have the latest chipset driver installed. Plese help if you can, I have built a lot of systems, but have never came accross this problem. Just when now I've got something else to learn.
