Guest Mark Posted October 1, 2007 Posted October 1, 2007 After using HP desktop w/out problem for 2 years, started having problem with monitor blacking out when computer went to sleep mode. Would not come back on when rebooted or restarted. Had to click monitor on and off to see screen, click on help utilities to restore to prior settings. Then monitor comes on. Heard it could be software problem but can't find it. Virus scan comes up negative. Hardware scan comes up negative. Can you help me figure out how to identify the problem? Thanks!
