Just to add, I cannot help with the BSODs as I don't have my computer with me over here at Greece, but the bugcheck 0xA00001(etc, can't remember how many zeroes) is a unique bugcheck given to AMD GPUs AFAIK, if that is the case then it may not be getting sufficient power from your PSU so replacing it should fix that problem.
Then again, I've seen at least 4 of those bugchecks in the past 2 weeks which is very strange, could be a bad driver but I can't check.
Anymore BSODs and Patrick will sort you out, he knows what was doing.
I'll see if I get any time to monitor this thread in the next few days.

Jared
