I am running a hp-compaq nc6000 laptop. with windows xp.. my problem is that my computer is now shutting off by itself, and when i push the power on button, at times it will turn on, but will not boot and it shuts down again. and the times its on- if you bump it, it will shut off. it does this on safe mode too, and when i am in the bios when i try to check the hard drive. i tried system restore, that wont work either. i also got a blue screen saying, IRQL_NOT_LESS_NOT_EQUAL too. please help me!!!!!!!!!!!!!!!.... Alot of people told me that it could be overheating but i am getting second thoughts about the power supply.

I can't help you with the BSOD much, because it didn't happen to me yet and you didn't describe the parameters of the error (the suff after IRQL_...) which can be of more help. Although, the overheating problem would just turn the book off (without a BSOD, probably). My father has a nc6000 and it also seems like when on load, the fan goes nuts. But on idle, it's fine. Actually, it just "died" couple of minutes ago .
This seems more of a HW and/or SW problem than overheating. I found a link which can be of some help to you:

Based on your posting, it is very likely the followings ( not in any specific order );
1. Too much dirt and lint clogging the cold air intake or hot air outlet to cool down your CPU.
2. The thermal paste between the CPU and cooling fan has aged out and requires a new paste.
3. The cooling sub-system is defective and could not remove the heat faster enough to let the system to operate within the designed thermal temperature ranges.
Before open up your notebook, you can try to use a small hair dryer to blow some cold ( cold ) air into the cold air inlet and to force out some of the dirt or lint from your system. It may make the system to run a little longer and let you go to safe mode.
If you think you hav the skill set to open the notebook and perform the above mentioned step 1 or 2, let me know and I will try to find the nc6000 service manual for you.

@ Skillz: I'm partially with Clinton on this one. It's worth a try to clean it. I'm gonna try and check the paste on mine (just died this morning, won't boot, just the battery LED lights up (no blinking) which, after some digging, seems to be a board failure)
@Clinton: Sure, put the manual up here. I personally could use it, although I don't think it's going to make any difference in my case.
I have taken apart my share of PCs - be it notebook or desktop. So no newbie here. Just a proud owner of tx2510us (who's hoping it will last more than what I've heard), already put new paste in this baby a year ago, made a hell of a difference, planning on modding the heatsink and cooling overall because HP obviously skipped that). The nc6000 is my father's old company book, which I've been taking care of for 5 years.

I have a similar problem with my nc6000. It will work fine in my room in the basement of my home but once I start going up the stairs with it, it goes to blue screen and restarts. If I start the computer up stairs it will fully boot up and then blue screen right when it’s done booting up. Sometimes it won’t go to blue screen until like 5 or even sometimes 10 min after that. But if I was down stairs it won’t do it and I can leave the laptop on for days without any problems.
