it cycles itself - power-up, shut down, power-up, shut down, power-up, shut down ............ I get as far as begining to log on to my PC and it reboots. If i do nothing it reboots at about the same time as it would take me to log on.
I have now managed to quickly log on and it didnt reboot - No, it asked me to register Windows? - did that and now it seems ok.
Now the frustrating bit. I got this far last night, but when i switched on this morning it was back to reboot, reboot, reboot - quick fingers- loged in - asked me to register windows - done that - now here i am back to being online, but know that as soon as i log off i will be back to rebooting again.
I have tried to use the restore facility, but it wont let me. Tried to get into Safe mode and have to be quick to get there.
Have run AVG, Adaware, Spybot, Trogan Hunter and CwShredder.
