It is slowing down my PC so much I can't even open anything (not even Start menu) before it crashes. I've tried booting in every mode available at the F8 screen. If it's one of them that loads your desktop background I still get the timer. If it's one of the Safe Mode's it will usually crash before I can even click my username. BSOD shows that's due to MEMORY_MANAGEMENT. Also, when booting in safe mode it takes a long while to load SPTD.sys and sometimes freezes at that point, dunno if that's important.
I've tried the Recovery Console, but the problem came back in minutes. I repaired my XP install from the CD but that did no good.
Basically, I can't even get in to my system long enough to do anything
