All I could do was boot into safe mode and restore to an earlier date. I tried F8 safe mode with networking but explorer kept trying to crash and send error reports(lameacm.acm was the cause of these) If I din't click 'send' or 'don't send', I was still able to browse around, use regedit, event viewer etc to try come up with a solution. Tried older cpu drivers, new amd64 one from AMD www to no avail plus what is fips???? all I could come up with was summat to do with cryptography?¿? so I thought maybe a couple of services needed disabled/enabled but still the same BSOD. Pain in the butt this, would like to see this processor running a little bit quicker in 32bit XP.
