|yes its the common reboot cycle during windows startup. Most i can fix by boot into safe mode, disable 1 by 1 startup process until it boots up proper.|
But with this one safe mode won't boot either.
From what i have found, 'Last known good configuration (advanced)' only works.
Lso found out customer bought a rogue AV caled SpywareStop which infected the PC, and she cleaned it with SuperAntiSpyware. Since then has this reboot problem.
Seems to me every time i touch registry it gets in this reboot cycle.
