Why does Windows ME constantly hang up on me? It usually happens when I open Windows Explorer. The machine just stops moving; I can see the screen, but nothing moves, and I can't use ctl-alt-del to reboot. I have to manually press the restart button. This just started happening, and now happens a couple of times a day. Is it a memory thing? That is my thought. But I need to know what to check. Please, please, please (in the words of James Brown) can someone help me??
