Laptop overheat?

[Kaousama]

I recently upgraded from XP to Ultimate 32 bit 1.7 on my older HP Dv4000 (I'll be installing Ultimate 1.8 64 on my newer DV9000). I did this because I liked the improved performance I got on my newer system and I was hoping a new OS would fix my problem of the laptop shutting down when doing processor intensive tasks. In XP, everytime I'd try to play games or had the system up too long (about an hour) it would just suddenly shutdown. I thought it was an error I made in XP after modding it and such, but after using Ultimate Edition it will still shutdown after a while. The CPU doesn't feel too hot when I touch it, and the fans sound like they are running. Is there a way to check/log CPU temperatures or does anyone have any suggestions as to what it could be?

This may very well be a hardware problem, such as needing Thermal paste between the CPU & Heatsink,
(or a lump keeping it from seating properly)
I've had a bad fan on a video card cause the same thing. (on a tower)
or something you changed in the mod, like restricted airflow.
It might also be caused by the Power management in the Bios not doing it's job.
Have you tried a Bios update? (last resort)

We've had users that disabled the power management in the bios and had their laptop heat up.
We've also had others that ran both the Bios power management And all the software power management, built into Ultimate Edition, and had the 2 fighting for control. This made for an unstable & quirky system.

Since you modded your case, I would look to the hardware first and recheck everything, before I looked elsewhere.

Very good advise LeadFingers! Couldn't have said it better.
