when I go to watch DVDs or access the DVD in DVDFab, i get the blue screen of death. it flashes on too fast before it restarts my PC, to read the message. When I try to watch a DVD in DivX, I get a message saying my video card is incapable of watching DVDs and that I need a better video card. any suggestions as to what this might be. This is on my older PC. It has an MSI mobo with 4gb of memory, a pentium 4 3.2ghz cpu, and a diablotek v7500 128 bit video card. It was always able to view DVDs before i installed Win 7.
