Disconnect all external devices except for monitor, keyboard, and mouse. If
the problem persists, reseat the video card and memory module(s) and check
other connectors. Although you checked to see if the power was OK, if new
hardware was added recently then the PW may not be rated high enough to
handle everything.

I never had such bad luck in my life. My co-workers computer will freeze
every time I turn on the damn computer. In safe mode, when I'm in the BIOS
setup. When I want to check for viruses. It took me 20 tries just to get
lucky to start it. Now it starts, but it freezes when I try to run
anything. I checked the power supply, with one of those gadgets, it is
working. The computer has WIN XP Home. I undeleted about 10 demo games,
that were on the machine, (my friends kids installs everything) ran Spybot,
it had 50 items, but so far, I was unable to run a Virus Checker, it
freezes on me. Is there a program that I can buy to be able to boot into
this computer, so it can check what may be wrong with this darn machine. Is
there a floppy version of a virus checker, that works from a WIN 98 startup
disk. My friend will also give me the original WIN XP CD tomorrow. Anyway,
the machine is a not too old HP P4. I also have to wait 5 minutes to be
able to turn the machine on again. Probably a safety item, but a pain in
the back, if you ask me. Any help is appreciated. I went on Google, and
looked for any help, the only thing I get is places that wants to send
pop-up's ..............Peter
