Well, according to your post, you did 3 things at once:
- Ran on 1 stick of RAM
- Disabled the onboard graphics
- And installed W7 fresh
So which one of these solved the problem? It's hard to tell when you do it like that. (Or maybe you know something that we don't - yet )
What I would do is assume the fresh install was the solution.
There is no need for the on board graphics to be activated, and that alone could have been the cause of a driver conflict.
Therefore I would think you could reinstall the RAM and test to see if the behavior returns.
If it does, then buy new RAM. If you can't find the exact same model of RAM to match the other working stick then it would be best to by a matched pair (or set).
Let us know what you find.
