When i first installed SP2, it froze A LOT, i did a system restore and everything was fine again.. a few days later, i tried again, and it was happening again, but not as bad as before.. part of the problem seemed to be my winamp5 for some reason so i got rid of that and it seems even better but it still occasionally (maybe like once or twice a week) just freezes so badly i have to press the reset button.. this also means there is no error report to tell MS what is happening
