it seems that sometimes, not everytime, when i open a folder on my desktop, or even if i start internet explorer 6, my pc will restart. I dont know what's causing it to do this, i dont have any viruses, and i have no spywares. Im using Win 2000 SP4.

Pleas help, and thanks for any help in advance.

Welcome to TechSpot

Can you fill in your User Profile with PC-info in "user cp" at the top please?
After that me may be able to help you.

ok, i filled out the optional things as you suggested, i dont know if you wanted anything more.

The problem sticks out immediately. You have 2 different types of memory. Take either one out and see if the problem dissappears. Try to swap the piece with the lower spec for an identical one with the higher spec. 512MB is enough for normal use anyway.

i've tried one stick of ram, the 400mhz piece, and then i went into the bios, and changed the ram speed to auto. I learned there was some ntoskernal errors, then it claimed i didnt have an os. I changed it to 400, same thing, then back at 333, it worked fine, except that in win, it still restarts when i open up a folder or ie6.
now im testing my stick of 333. im currently hoping, sorta, that the problem remains so that i will be sure its not my 400 ram, im hoping its just a format issue. but even so, its still anoying to format.

yes, and it still restarts as i notice

Did you run the updated versions of Adaware and Spybot S&D?

well, i updated all my virus and spyware defs, and it found nothing too bad. I had no viruses, and a few spyware things, some things i killed, but i dont think its these that are the cause, its possible, cuz ive had them befor, they come back somehow

D/L Hijackthis here. Instructions are on that page

Your PC might have been taken over by some malware. Test it with above program.

i've tested it with that app before, when i had some other errors, but my ver might be old now. ill post the results

ok, here it is, i just posted the *.log file

*.txt now

any threats in my log?

Stop Norton Cleansweep, Netlimiter, Teatimer and Adobe's acrotray from running at startup.

Try running without this Alltotray (what does that do?).
If you don't use AIM, uninstall it.

You wouldn't happen to have any error messages in the even log by any chance ?

the AllToTray is just a simple app that sends windos to the system tray instead of the task bar, just to clear out space.

and yes, i've had some errors in my event log, i posted them i think, called event viewer errors, i listed 3 major ones and 1 minor one.
