Simviation Forums

Since I bought my new system I've been unable to fly in any sim (SFP-1, Lomac, FS2k2) for more than 30 mins, sometimes they will minimize to desktop and then be brought back up as if nothing happened only to do this again after a few minutes, others they will simply die and leave me with a black screen... the status message dosn't tell me anything:
"An ATI product has encountered a problam and may no longer function properly... please restart...."

Anyone have any ideas?
