Computer Hangs afer 4 hours of operation.

Computer P4 2.0
O/S: Windows XP Pro.
RAM : 256 MB
Mother board : ECS P4

The computer works fine for say 4 hours. Then the whole thing freezes.
Then when I do a cold boot. It hangs when runing the BIOS ( during the
intial phase of finding the harddisk etc).
If I shut down the computer for 20 mins or so it works fine past the
BIOS running stage, but hangs after the XP comes up.
If I keep the computer shut down for a day or so, it works fine again
for next 3-4 hrs and then the problem starts again.

I have changed the Hard drive, BIOS battery etc but the problem still
continues.

The computer is still a fresh install.

What might be the problem. Is it the faulty processor?

Thank you
Kiran Math

Sounds like it might be a part overheating, and then when it cools down you
can run OK til it overheats again.

<>Go into BIOS and look for a heaing similar POWER, STANDBY, etc. Your
Bios may be set to go off automatically in 4 hours. Reset everything
in your BIOS with NO automatic settings. When you're done for a while
but intend to come right back, simply turn of the electric waster, the
monitor and leave everything else, 3.5 to 5v DC, on.

You problem seems to be one of two thing
1. your CPU fan may not be functioning properly. open the cabinet and
see the fan is running quite speed. you may see it from the bios and
motherboard monitor software (download and run it) also. Watch the
mobos temperature and find if the temp crosses some limit the system
will hang.

2. other prob is purely hardware. If any of the capacitor in line to
the cpu or any other bus or even a capacitor in the power section is
weak this may happen

Thank you for quick reply. I will follow all the suggestion and post
back when the computer is working OK.
