system restore has got this, know-nothing old fool out of a hole lots of times. the other day , just when i needed one of those that i had routinely carefully created, they had disappeared. can anyone tell me how and /or why? perhaps my faith in restore points is misplaced, i'm clueless about computers. two days ago my PC got stuck on the screen that has the white writing about memory and drives on it- what's that called? anyway, F2 miraculously got me to the option of a safe mode restart and thence a system restore and the old 'puter seemed saved-which was relief.i didn't have a clue what i was doing or why it worked. i'd probably have been better off sacrificing a chicken who knows? i wish one could store the system restore information whatever it is on another drive, but i don't suppose one can, can one?
