I got windowsxp amd 2800 cpu 2gb memery 2-250gb hard .
computer shuts down .You can not boot up unless you turn off
thepowersupplythen turn it back on.
I tryed a newpower supply.Then I tryed a new hard drive and unplug other
drives Tryed to load windows
It loads abouts halfway then shuts down.
Swapping parts will not provide a definitive answer. Best obtained
is "it appears to be fixed". Currently I see nothing that identifies
the problem as either hardware or software. IOW you have not broken
the problem or diagnosis into parts - then solve the parts. Trying to
fix it by reloading Windows may have created a new problem - defective
Windows installation. If so, then you have exponentially complicated
a solution by trying to fix something before discovering the problem.
Step back. Let's first learn what is or is not completely good or
completely known bad. All doors can appear defective inside a house
when, in reality, the foundation is defective. Do we then fix doors?
No. First we establish what is and is not good. The foundation of a
computer is a power supply. Only way you will get a definitive answer
is to measure voltages with a 3.5 digit multimeter using procedure and
numbers provided in "When your computer dies without warning....."

Then post those numbers here for potentially further useful facts.
Is Windows functional at all? Can you still boot in safe mode and
into other options (ie manufacturer comprehensive diagnostics) by
pressing F5 or F8 when power is first applied? Is the computer
manufacturer a more responsible one that provides comprehensive
diagnostics for free on disk and on web site? If not, then get
diagnostics from various component manufacturers. A shorter list of
components that may cause boot failures include sound card, disk
drive, video processor, motherboard, and memory. How far did system
get before failing? Did BIOS complete execution? Boot failure?
Your memory test did not (and would not) provide useful facts - the
necessary definitive 100% known good or 100% known bad results. But
then that is what memory diagnostics (in combintation with another
diagnostic tool - heat) or system (event) logs would provide.
Of course all this is only informative after power supply 'system'
is confirmed. Yes - a 'system' and not just a power supply.
If Windows can be booted in safe mode, then what is stored in system
(event) logs - or did you destroy that useful information by trying to
fix windows?
Above are first steps and the attitude to break this problem down -
isolate the failure.
