Putting the original graphics card back fixed everything. Except it was dog slow which is why I bought the 1900 in the first place. I finally bit the bullet and bought a 4870, which, while officially unsupported in my first gen Pro is dead mega-ace. Of course you don't have those options on an iMac, yet I'd strongly suggest blowing the fluff out of the 1600's heat sink. -- To de-mung my e-mail address:- fsnospam$elliott$$ PGP Fingerprint: 1A96 3CF7 637F 896B C810 E199 7E5C A9E4 8E59 E248

Well, I wouldn't have the 1st clue on how to open this case, and am reluctant to do so until heat is the only possibly cause left, but the temps I posted earlier tell me that isn't the problem. Pete.

Looks like I'll be using my old Windows laptop as my main computer for the coming months until I can afford a new machines :-( Time to make sure my backups are up-to-date and external drives are converted to NTFS. Pete.

Unluckily, assuming yours is a 20" screen, http://www.everymac.com/systems/apple/imac/faq_cd/imac-intel-processor-upgrade-video-upgrade.html#video says that your graphics are soldered to the motherboard. So there's no real repair option. The only real downside of having lovely integrated all-in-one systems...

Your posts have needed re-wrapping earlier on in a thread than most others. 72 chars is what MacSoup uses.
