My computer restart itself in boot up

Hi,

I'm a WIN XP Pro edition user. I do not have SP2 in my system as it troubled me a lot.
Today, I was working with my PC when it suddenly rebooted itself. During reboot, when it reached the Win XP logo with a left to right bar, it rebooted itself again. The 2nd reboot was successful but after several minutes the same thing happened, only now, I couldn't get into the system anymore.

I tried to enter the system using safe mode, but it just stopped and gave me blank screen and i have to reboot the PC manually.

I tried to repair the system using Win XP CD but it won't repair and gave me the error message:
"PFN_LIST_CORRUPT" microsoft technical support STOP: 0x0000000A (0xA7A278C2, 0x00000001,0x00000000,0x807F0773).

I've unplugged all external hard drive except for my mouse, monitor and keyboard but didn't help.

I don't want to reformat my PC as it contains a lot of useful information. Can you please help. I need to work with my computer urgently.

Thank you.

Bugcheck code 0A is IRQL_NOT_LESS_OR_EQUAL is usually caused by fauly RAM, CPU, M/B or software error at device driver.
0x0000000A (0xA7A278C2, 0x00000001,0x00000000,0x807F0773).
Bugcheck code 4E is PFN_LIST_CORRUPT is usually caused by faulty RAM or CPU

After the combine the usual root cause of OA and 4E, your problem is faulty RAM, CPU or M/B.

In order to confirm your problem is related to hardware. Check system event 1001 and it has the content of the blue screen
Control Panel -> Adminstrative Tools -> Event Viewer -> System -> Event 1001. Copy the content and paste it back here

Attach the following Doctor Watson's files at any webspace.

1) Reseat the memory stick to another memory slot and reboot
2) If you have two memory stick, maybe one of them is bad. Take one of them out and reboot your windows.
3) If it fails, swap it with another memory stick and reboot

Hi,

Do you know how to do bugcheck?
Anyway I replace my RAM with a new one but didn't help.
I tried to reinstall a fresh copy of win XP in a new hard drive, didn't help too.
The win XP cd boot up until the license agreement, and the "IRQL_NOT_LESS_OR_EQUAL" thing came up.

I can't go to the control panel as the windows won't load up. Any idea?

Thanks.

Using a brush and a vacuum cleaner should do e job...

Bugcheck code 0A may be related faulty cache memory at CPU or BIOS. Try disable cache memory at BIOS. Maybe it can resolve your problem.
