To lift the front bezel off the iMac, simultaneously:
-
Use your thumbs to press in the RAM arms and hold the iMac down.
-
Use your index fingers to pull the small bridge of material on the front bezel toward yourself.
-
Pull the front bezel up with your index fingers.

Once the small bridge of material has cleared the RAM arms, lift the front bezel by its lower edge just enough to clear the bottom edge of the rear case.

Competed the GPU replacement following this excellent guide. My iMac is as good as new, after weeks/months of randomly fragmented windows. Would not rate the repair as difficult, though, since no soldering/desoldering was required. Took between 4.5 and 5 hours (forgot to check the exact start time).
thx for yout reply. And i have a question.
I have done all these works. But i can't get the replacement of the GPU.
can i ask you where to get the replacement of the GPU?
it is very hard to find the GPU because it is pretty old model

Having similar issues with fragmented windows and then freezing in some cases. Very certain it is the GPU - do I replace the paste or the board?
Fraser, I suggest checking a youtube video on how to reset the GPU's solder connections. Apparently, with the overheating the solder connections loosen causing the fragmented windows and then freezing. Normally one would replace the GPU assembly, but since these are extremely hard to find and costly, resetting the solder connections might be the only option to try.
At YouTube.com search for "Casual iMac Video Card Repair".
I've been meaning to try this repair for two years now . . . finally going to give it a try.
