I've searched and looked for a sticky but couldn't find anything. Searching for guides brings up half of it asking you to pay for it 
I've fixed XBox's before, but I've forgotten a part of it. Here's what I've done so far:
- Stripped XBox down
- Removed X-Clamps
- Cleaned CPU and GPU with Acetone
I know next I need to:
- Add thin layer of compound
- Put Heat sinks back on and do them up finger tight (using replacement bolts and washers (not nylon ones))
Now this is where I'm stuck. I remember you put the board back in the case, etc, leave the covers off, turn on with all cables connected and rest fan over one of the heatsinks (can't remember which one). You leave it on for a few minutes (don't know how many) and wait for a certain light to come on? Please help! If it works I'm going out to buy F1 2010
