xp pro keeps restarting

[Molecule]

Got xp pro on my desktop with 2 gig of ram on raid 0 + a standard drive for
my documents. Two months ago it started going off by itself at random,
decided to low format the 2 drives and rebuild the raid.
Now, after a few months, it plays up again. I would love to take the whole
thing and throw it out of the window, but I need to work with it. Now it
switches itself off, it waits 2 secs and it starts on its own again.....at
random...wow...lovely
I only have my graphics card and sound card on my motherboard and always
keep the system in top condition, no unneccesary programs or crapware.
What I did:
memtest no probs
sfc /scannow
restarted in safe mode: no probs
Went in System Property/startup and recovery/ and unticked " automatically
restart. Still not getting error codes or blue screen
Updated xp
Updated hardware drivers
Scanned the systam for viruses and spyware
Check the battery on the motherboard
unplug the tower and reconnect

The thing I cannot understand is: how can the computer start by itself?


Many thanks

Could be a flaky power supply? Or a heat related problem? The computer
can restart if it is set to resume to the last power state in the BIOS,
this is a setting that tells the BIOS what to do in case of power
failures or power interruptions, when the power resumes it acts accordingly.

It's a hardware problem. Either the power supply, motherboard, graphics
card or sound card, is failing: probably the ps or mobo since it
restarts, but the ps can be overheated by any device that is drawing too
much current.

You might try a hardware newsgroup.

Got a liitle utilities that monitors all fans and temperatures, no probs
there it seems.
Power supply.....yeah good one.
Thanks, will probably have to get a new one, worth a try.

Bought all new components 2 years ago, bummer if it is the mobo or ps
Was even thinking, how about the reset button on the tower? could it be
dodgy?

 

[db]

sometimes boot looping
can be corrected by
using the command

chkdsk
fixboot

however, you would need
to boot with a xp cd then
execute the repair/recovery
console to get to the disk
prompt to run commands.

Had a similar problem a few years ago with my then current system, except
mine wouldn't reboot after quitting. It was if someone just turned off
the power. PS tested okay, but replaced it and the graphics card
anyway. Didn't help. Cleaned everything. Reseated everything,
including CPU with new thermal grease. Didn't help. After about 4
months of this, I finally discovered that the CPU was the culprit.
Replaced it, and the system ran without problems.

Before buying anything, I would sure go inside the computer (assuming it is
a PC) and disconnect and reconnect all the connectors (power cord unplugged,
of course) and remove and reseat the ram, vid card, sound card,NIC card or
whatever cards you might have in there.

I believe that if you search in Google for how to test a power supply, it
may have a way for you to determine if it is bad, before spending money.

DL the manual for your mb and see what options there may be for your
problem.

PS: Make sure that dust is not clogging your Power Supply Unit cooling area
and, when you unplug and reconnect your connectors, look for burnt or melted
plastic or pins.
