Lately I have had a rash of Imac computers come to me with Blown Graphics chips due to overheating and poor ventalation, there are a few steps I us to see if I can get the comp up and running that ultimately culminates to reballing of the graphics chips, but detail intensive. its a fairly easy repair, so this being my only day off this week I had a thought do some PM on my own computer to save me from having to dig in deeper . THIS IS WHAT I FOUND! I should have been charging the dust bunnies rent . Oh well 1.5 hrs later ( i stopped for breaky) , all the beasties have been removed and now my comp is running all components at an average 85 F much cooler than before. I was curious if you guys ( and ladies ) do your own repairs or do you actually pay people to this for you ?
