So I began to use my 24" 3.06 ghz imac yesterday like normal, except it was locking up playing full screen videos and WoW. I couldn't even force quit the applications, the sound was still playing but I had to power cycle to get actual control of the machine again. Further investigation proved it was also happening in windows, so I ruled it to be a video card problem. I called tech support and they ran me through all the normal stuff and I figured I was going to have to send it away to be fixed. Come to find out that there's an apple certified repair place literally one minute from my house. Took it over there and they are going to diagnose it and let me know whats up. The machine is exactly 1 year and 1 month old, so I'm reaaaaaaaaaaaaaaaaaally glad I got the Apple Care. Personally I think theres just some flaw in the imac casing in that if it gets heavy use for a year (like it did with me) the graphics card is just bound to fry given how much heat is generated. I only started using SMC fan 3 months ago and maybe that gave me a couple extra months before it finally crapped out. I plan on using it from the beginning once I get it back. I just really hope it doesn't cost me anything.
