I fought with Vista for a month with the black screens, lock ups, and loops. The dreaded "Display driver has stopped responding" error has returned to haunt Windows 7. At least for me. I play WoW a lot, some Bioshock, and recently Universe at War. The error is very random. Sometimes it affects the game right off the bat requiring a restart of the computer (if not it will just do it again). In Vista i went through all the trouble shooting tips found on the web including, trouble shooting the ram, testing voltages, overheating problems, underclocking video and FSB settings. I have gotten Vista to be fairly stable with this problem. Is any one else seeing this monster rise up again? If so let's get this out in the open to Microsoft. I do not want to be using XP for the rest of my life. By the way, I do have XP, Vista 64 ultimate, and now Windows 7 Ultimate 64 loaded on my system. They are all on different drives. I only hook up one drive at a time so that there is no dual booting going on. So far I must say I really like Windows 7. No glithces on install and it even put in my wifi card without removal.
