EDIT: for some reason i was mistaken, its a 2.33 not 2.4. Obviously, assuming I had a thousand dollars lieing around Id fix the mac. However the problem is im finishing up my last year of college, therefore money is incredibly tight. My Imac was bought in March of 2007, and the warrenty is expired meaning no free repairs. Ive never actually brought a computer in to repair at the apple store and Im a bit hesitant to just bring it up there and ask them to repair it, because if it winds up costing more than 400 or so its way out of my current budget. Ive heard horror stories of people bringing in computers for repairs at the store only to get back a 1,200+ dollar bill. At that point Id (sadly) be best off just buying a new computer. What I would like to do is just buy a new geforce somewhere and install it myself, but Ive gotten varying information about whether or not this is even possible. I think this would be by far the most economical option, but most imac video cards are (from what i understand) pretty much permanently attached to the mother boards, the exception being (again from what ive gotten from random sites) 24" imac geforce's. Can anyone varify that its possible to replace a video card in a 24" imac? Only mac specific video cards work in macs correct? If thats not possible, whats the base cost for repairs are from the apple store? Do they charge say $200 or so fee up front regardless of the issue + time and parts? How does that work? How much should I expect to have to pay? Any and all help, even if you can just answer 1 out of the 100 questions i have would be GREATLY appreciated. Is it even possible for me to get a free repair since its a faulty video card issue and no fault of my own/misuse?
