I recently upgraded from one old computer to a less-old unit. My original comp was running XP and a pentium 4 processor. My Radeon HD 5770 worked great in it. I decided to upgraded and start using my wife's computer for gaming so I moved the HD5770 into hers with VISTA and now my games are freezing and stop responding after about 5-15 minutes. Crysis for example was perfectly fine on the XP machine but now freezes on the VISTA. I just don't get how it can be fine in one machine but not in another. I did a fresh install on the VISTA machine. Did all the updated through windows. It has a new hard drive and I moved my 550W power supply in as well. I'm using the latest drivers and all to no avail. Nothing I do fixes the problem. Is the card screwed? Or am I missing something?
Any help or thoughts would be great....

Thanks for the input. I'm going to try Drive Sweeper as it was suggested by XFX support as well. The only other video adapter was the onboard video so I wouldn't think it would be the problem. The drivers are the most up to date. Only a few weeks old actually. Computer is up to date too. SP2 and everything in between. I've been doing some research and though this model video card is recommended here on Tom's, it seems to receive a lot of bad reviews and reports of similar issues to mine.
