Assuming you have the latest drivers...
How far along are you in the reformat/reinstall? Depending on the situation, I would probably just try reinstalling again and see if it changes anything.
If so, remember to install everything in the best order:
-Other hardware drivers
-Other windows updates
I think thats the order...
... that is, if you don't already do this. I do know you can have installation clashes sometimes, which might contribute to the problems...
Anyways, good luck.
You're the guy from that hamburger train, right?
