On Start up Windows XP REboots.

On Start Up Windows XP Reboots.
I run Windows XP SP2 Fully up to date. AMD 1900. No viruses Registry fully cleaned.
When I start up, after the welcome screen the system shuts down and reboots. Sometimes it will go through to loading up desktop then reboot. It is not consistent as it will either start with no problem or reboot up to 6 times before it completely loads up.
I get the message from Microsoft there is a DEVICE DRIVER problem. Then I get this error message:-
STOP:0x0000007E (0xB32F3145,0xF742AAEC,0xF742A73ECool
Base at B32ED000,Datestamp 4341a407
I contacted Symantec who inform me that their program
installs a Kernal driver a and this may happen when there is a limited amount of kernal space.This could also be a IRPStackSize registry value problem, and how to change this. This was done and rebooted manually 7 times, no problems! The next day when I started machine-it started its rebooting again. All these numbers are gobbly-**** to me. If anyone can work out what the problem is and offer A solution in plain simple info, I would be grateful.

The "device driver" is an extraneous error message.

What kind of computer are you using? Have you done a visual inspection of the motherboard when these problems first occurred? Does your computer have a Bestec brand power supply?

The reason I am asking this is because many E-Machines computers from the era when you bought your Athlon XP 1900+ system had a known design problem which would lead to random crashes, bluescreen errors, random reboots, and eventually a condition where you turn the computer on and the fans start but nothing gets displayed on the screen and nothing else happens.

What happens on these computers is that poor quality electrolytic capacitors on the motherboard start swelling and leaking. When this problem first begins, it APPEARS to be a software problem or the result of faulty RAM.

On some computers with this problem, I noticed that I could boot to the BIOS with no difficulty, reformat the hard disk from an MS-DOS startup disk, and even load Windows 98, but attempting to install Windows XP results in random "STOP" errors during the installation, and a failure to load to completion.

The fix is of course a new motherboard, and this problem is so common that replacement Socket A motherboards are still being made and sold. Check out, or another reputable reseller and look for a micro-ATX motherboard that accepts Socket A AMD processors.

You can reuse the heatsink, processor, memory, and everything else from the old motherboard. Just make sure to scrape off the thermal pad from the heatsink and processor, and then apply the correct amount of thermal grease to the processor before reinstalling the heatsink. Or you can purchase a new heatsink that has the grease preapplied for you.

Windows XP Reboots on start up

Hi sbill,
Thanks for the info but the system has been running normally for about 4yrs with no problems. This only started about 6 weeks ago. I intend to purchase a new machine at the end of the year. At my age and my TECHNICAL ability I think that changing the board is a bit beyond me.
Thanks anyway and I will look into your comments.

You are sure that's the problem, I have a spare Asus A78NX-E 400 fsb.

New Power Supply

The first step in diagnosing a continual reboot is to try a known good (preferably new) Power Supply. Forget the motherboard, you can't dio it without a good PSU.
Especially at it's age, it is probably failing, and the addition of additional or upgraded devices (esp vid cards puts an enourmous strain on the PSU)

Ever hear of capacitor aging - it's just what it sounds like - the PSU puts out less power the older it gets.

Only after testing with a powerful good PSU can one even consider a bad motherboard, or anything else

Step 2 is to test the RAM, either with new RAM or Memtest86 (google - it's free)

People love to jump on mobos - a bad PSU will eventually take yours out so check it now
