Freezes in safe mode at crcdisk.sys. nothing on F1 or ,2.Scaleo J PC. All because I loaded tuneup utilities 2012 and my PC went into this loop mode.
Boot to dvd and try repair or other checkdisk tools. Text, talk, drive...CRASH.
Hang up and drive @#$%^^
Do some googling on crcdisk.sys - as often as not it appears to be a hard drive issue. Having said that most of those magic fix-all programs seem to often wreck the system software and registry. Always pop back and let us know the outcome - thanks
