Ok here's my problem, awile ago my computers Power Supply
got fried (a power surge), so I got a new one (a COMPUSA
300 WATT ATX)and ever since then my computer's CPU would
get up to 100% and stay there (it says STYSTEM is using
it) I've tried many things but nothing works, also when I
try to shut down my PC stays at the Windows is now
shutting down screen for hours, and when I hold down the
power button and turn on the computer, the CPU is still
at 100% (unless I let it shut down, then it just works
for awile and then it gets back up). Please Help

If a power surge got you power supply chances are it got
other things too. But what wattage was your old supply.
Oh and don't Dell computers use a different pin out on
their supplies so a standard one won't work. So you may
have done damage by installing that supply.

I'd say more of your system is fried from the surge, and possibly from the
ATX power supply (Dell does not use standard ATX power supplies last time I
checked). However, it does seem from your message that your computer isn't
totally toast (drives work, etc.). If you have Dell's complete care
warranty they will take care of you, if you don't.......

Here is what I would do.
1. Purchase a new case, and motherboard, and possibly new memory (you may
want to pick a P4 motherboard to try and reuse your old CPU, you'll probably
want to cast aside your RDRAM in favor of DDR SDRAM). MSI's NEO series of
motherboards feature some nice auto over-clocking stuff
2. I'm not really sure if I would buy a new CPU or try and recycle your old
one, that is up to you.
3. Put your new motherboard (and possibly CPU and memory) in your new case.
Put all of your old hardware in from your Dell that you need to get going
again

Claim on insurance? Otherwise depends. Your standard ATX PSU is almost
definitely incompatible but at a guess, unlikely to have caused more
damage. PC Power & Cooling do a 300W Dell PSU:

but fitting one is no guarantee that the m/b or other components haven't
been smoked. Do you know that the original PSU was damaged & not
something further down the chain? Does the Bios screen (if your Dell has
normal access to one) show all IDE devices etc?

Unless to can swap components to another (Dell?) PC & work out wot works
you may need to return it to Dell (gulp) or Dell dealer if such exists.

From the symptoms you've given, I'd check the memory 1st by attempting
to run Memtest86 from a floppy or the memory in another machine. If it
got as far as telling you that the CPU is running 100%, you stand a good
chance of recovery. If Memtest86 runs but fails tests, rerunning to find
the same segments failing gives a high degree of certainty that the
memory is fried but random repeat failures could mean memory, m/b or
possibly but least likely the CPU is faulty. I'm surprised it boots at
all if the new PSU is definitely incompatible. Are there any Dell NGs
you could post to?
