Hi Joe and tjnbarbour,
Very good, good news guys!!!! Now all is working: My Pc properties, System restore, I can create new restore points. WONDERFUL!!!
How??? Perhaps you are asking. Well, I hope this be working always, if not is the case, I am sorry, but I will be here again. The solution:
I have uninstall the antivirus and take out from the startup list the ASUS monitor (because this last one was always the last to be charged). I have rebootet the system and...WORKING FINE.
As I told above, let's see if this is a lasting thing.
I want to give you, guys, thans for your help, interest and good way to teach me and also for your patient (specially because my English).
Please, do not let this wonderful forum. I will be back, and not for problems.
Cheers,
