Is my video card dying?

I have FS9 profiles set up for my 6800XT.I have it set to 4x aa and 16x af. It has been working fine, until trhe last few daysAs soon as I run FS9.exe it seems like the profile won't take...well, it will, but the second I change to a different aircraft the AA and AF goes away.This is for FS9 and FSX....and I'm guessing the rest wouldnt work eitherIt's quite strange actually. I can however, use a global profile and force the AA and AF and then it works fine.Maybe something happened with the registry etc??Or my card just crappin out?
