Skuste najst iastor.sys, ak ho mate, mozete sa pozriet na toto riesenie:

Launch regedit (start->run->type regedit, click ok)

Ok, now navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\

find the iaStor and iaStorV keys. In each of them, delete or rename the Parameters key (I renamed mine to Parameters.bad). Since this, no stop errors. I still get iaStor hang notifications in my event viewer (right click on my computer, click on manage to see the event viewer), however now it doesn't crash my whole system.

Good luck!
