Computer boots up to windows logo page no matter which option you push for safe mode or back to last good config??? it will try to run disk scan then shows logo and returns to boot system. Last use of system shut down was normal, nothing has been added… although there was a storm and the phone line was connected with out a surge protector but system was shut down during the storm. could this be worm Sasser ??? or could lightening have run in phone line which I doubt because it does look like a good boot until it gets to the logo. Everything in CMOS is ok. Any ideals???
