Hi every1 Until a few days ago everything was ok, running xp corp.edition, AMD 1.2 ghz, ATI 64mb AGP,20 gig HD, 526 mb RAM,CDRW,ZIP,cable modem. the problems that I'm having are: 1.- the settings for power saving are to turn off monitor after 30 min and HD after 35, this is not happening, after the screen saver kicks in it goes to the welcome screen and never turns off. 2.- if I press the sleep button the comp goes to an state that seems to be sleeping but it won't come back from it, have to restart to gain use. 3.- the power button for some reason now is working as a restart button, to turn off the computer have to go to the back and shutdown the power supply completly. I guess after installing something the registry got change producing these changes to my system, thinking this, I did a rollback 2 days back whe everything was working fine, but didn't work. I know that in this forum there is people who knows very well the windows registry maybe you can help me fix these problems. If anyone can help please post your suggestion. Thanks in advance.
