ok i tnk i may have found the problem, it was weird how i could log in to safe mode without network support, so i removed the ethernet wire,, and it worked,,however i first resotred windows to a previous date so that could have helped either...

to try that again,,,i put the wired back on, restarted (it didnt even restart it powered off) restarted again, powered on with the wire in, when loading windows it powered off again,.,

so i restareted windows again without the ethernet wire, and it starts up normally logs into windwo's fine etc etc,,,however i do get a mcafee issue,,so am wondering whether it could some sort of virus of some sort,,but it shouldnt really affect the pc powering on and off should it?

so i think that could have sold the problem, issue is, why all of a sudden?.,,,,and when i put the wire back in when i am logged into window's i can put the wire back in and surf the net as normal..really strange, i couldnt rollback the drivers, because there werent any,,,not sure what to do here.
