I got a E74 code today when I turned it on. I talk to someone at gamestop and they said that I might be screwed. I don't have any warranty left :wtc:
The x-clamp kit spring kit and heat gun should fix the solder balls on the traces between the CPU and GPU and have you going if you are without warranty.
There is a guy right next store to me here. Signs today named Matt. he does that for a hobby. Come by on day and talk with him. I think he is really cheap.
