I have a 450MHZ machine with Win2k, 256 RAM. I have the usual things plugged into it (mouse, kboard, monitor, network card hooked to cable modem, speakers). When I'm booted up and plug in my USB CDRW drive, the computer automatically loses power. I have to unplug everything from the system for it to gain power again and boot up. I never use to have this problem until recently. Any ideas?
