-   I have this card installed for almost a year. This week I was playing a game and the PC freeze. After reboot everything was Ok for like an hour. Same thing. Next rebot...freeze after 3-5 minutes. Next reboot doesn't even goes through POST. Next reboot halts in Windows logo. Next, loads Windows, halts after a minute. and on, and on... I removed the card and install an older ATI, Windows loaded correctly, but watching a video after trying to maximaze frozee. Reboot, Win loaded took a walk, came back and screen was frozen. Reboot again...seems everithing ok, except Im looking at task manager an some user name's processes are missing (???)-   davesdream
