Win2k keep restarting at different stages of starting process

I cannot specify which new hard/software starts the problem. The only one major event was it could not start at all about one month ago. Wait for a few days, it was OK for a few weeks.
A few days ago, it restarted itself: 2 t-3 time right after IDE check, or at the box for me to log in, or after i log in, or after it put up the icons on desktop.
There were a few times it restart successfully, with a box saying:"
printed error. attempt to index field 'start' (a nil value) stack traceback:
0: function 'showNag' at line 282 [file 'C:\DOUUCME~1\ADMIN~1\LOCALS~1\Temp\main_22.tmp']
1: function 'startup' at line 291 [file 'C:\DOUUCME~1\ADMIN~1\LOCALS~1\Temp\main_22.tmp']
2: function 'main' at line 1150 [file 'C:\DOUUCME~1\ADMIN~1\LOCALS~1\Temp\main_22.tmp']      "

Now, it keeps restarting at different stages. Each time it goes further into the starting process, until it almost finishes the desktop icons, then it resarts again. Keep restarting at an earlier stages, and going further. Never quit, the only point it stop to wait is the login box. It will restart here regardless i login or not.

I have checked previous answers at the data base. I unplug the external 6 USB devices. Uncheck the automatic restart. After that it request restart for it to take effect. I did not restart it right away. I then went on surfing the internet. Put a disk in the CDROM, then, it restart itself and now keep restarting forever.
Can someone help?

From your description it sounds like there may be a hardware issue.  Here are some things to try:

Open the PC's case.  Blow out any accumulated dust.  Check for air flow issues.  Is the case warm to the touch?  Make sure all fans are running.  Visually inspect the motherboard for bulged or ruptured capacitors.

Run a memory test with Memtest86+ or the Windows Memory Diagnostic.

The case is not hot or warm when i touch it. The PC keeps restarting and has not reach desktop/icons. Would like to know to run the test under such circumstances.
I started it at debug mode, it reaches desktop/icons after loading some start up programs in the task tray. Then, it hangs up forever(more than 12 hours now). What should I do?

The memory testers create bootable disks.  Create them on a different computer and then boot the problem computer with them instead of booting off C:.

If possible, have a friend burn you an Ultimate Boot CD and boot off that.

I put the windiag file on to the CD, not sure am i doing it correctly because it is only 278k in size. I inserted the CD in the CDROM of the problematic PC, the CDROM keeps clicking, and the screen showed "no signal". If i took it out, it will reach the window logon box, and restart itself after i login. Should i change a CDROM? How to do it safely?

After I removed the CDROM completely, the PC did not even start. It tried very hard, pump up power, and subside,  then pumping up power again, then subside. It cycled hundreds times. Then all of a sudden it proceeded to "window is preparing network connection", it resarts itself. Then it proceeds to "applying security policy' then restarts. It has been doing this for almost 30 minutes. What should i go?

it turned out that the problem was the power supply. Change a new one and it is OK now. I would like to close this case.
