For a few months now, I would be sitting at my computer and my monitor would all of a sudden go black and say "no signal". So I would turn the monitor off and then back on and it still said the same thing. After that I would just hard reboot my system, because I guess the system locked up because I try to use the windows keys and do a normal shut down, but it wouldn't work. So, when windows comes back it says the computer was shut down when a device failure accured and that device was the video card, btw i have windows XP pro. It also notes that it could be a driver problem, however its been doing this since the cat's 3.6 - 4.1, and I've also reformated my computer several times, however it still happens. Anyone have an idea how to fix this problem, or should i just RMA the card? Thanks for any input.
