T61 very slow

[montz]

I removed the active protection. Removed the Iostor thingy. Ran the supplied diagnotics at boot. But my system is so slow. It takes 5 min to boot to a state that I can work on. Applications will work for a bit then freeze. the mouse will move but i cant get into task manager or start menu. Tech support made me run diagnostics but it passed all the tests. I am forced to power off the system by holding teh power button. On reboot it does chkdsk. I had a few occasions where it would say c:\windows\system\ missiing (or something like that). I was forced to do a recovery. Anyone else haveing these sisues?

You delete the wrong parameter under regedit: iastorv, not iastor.
If after you delete the parameter you still experience freezes, uninstall Intel Matrix Storage Driver and Intel Turbo Memory.

Might be an MS issue. Read KB927891
