Ok... this morning I turned the computer on and it gave me 2 strange beeps... then booted up normally... no more blue screen.... (Not sure whether I should be happy or afraid that it's gone w/o me doing anything.)
Every time I turned it on last night (total of 3-4 times), it blue screened at the windows loading sky blue screen, and just froze completely the 4th time.
I'm not quite certain what the message said though, it went up for like 3 seconds, then the computer just automatically restarted.
Also another thing I failed to mention is that I also installed SP2 yesterday, if that would somehow be an added cause of the abnormalities...
