using win xp, home, sp2
lately when i click on Ctrl-Alt-Del to end a frozen task in windows and click 'task manager' in the security panel, the screen just goes blank (yet still light up) and nothing can be done from the keyboard. even the computer on/off switch won't work! i have to unplug the computer and plug back in, then start again from scratch. so please help me re configure windows explorer or whatever else is causing the blank/inoperative screen after clicking 'task manager' in 'windows security'.
