Actually if you can hear the fans running then what you need to replace is the thermal compound on the processor chip it is like 5-10 dollars cad at your local computer store and you can re paste it on your chip and it cools the laptop substantially i had the same problem... it oveheated within minutes and now i can let it sit right on my lap or on the couch and every 1-2 years it should be replaced... and it will help make your laptop have a longer life span

This advice relates to the Compaq Presario 3000 Notebook series but may also apply to other notebook computers as well.
The heat sink and fan assembly is probably clogged with dust and airborne particles. The clogged cooling parts can lead to heat problems with the CPU. When the system (CPU) gets to hot, the fan has to kick into high gear to try to cool things down. Once you remove dust and debre from the heat sink fins and fan, you will immediately experience better cooling and less fan usage. Your system may also be set for dynamic switching of CPU speed. If you CPU gets too hot, the system will reduce clock speed and ramp up fan and everything will slow way down. Use a good system monitoring software such as Notebook Hardware Control to monitor your CPU temperature, HDD temp and so forth. When the system starts getting too hot, first look at clogged heat sink fins as possible culprit. If you're good at electronics you may be able to service the unit yourself. Get a copy of the system's Maintenance and Service Manual or have a professional do the job for you as you will have to partially disassemble the computer to clean out the heat sink. Depending on the system, the job can take as little as 15-20 minutes once you become proficient at it.
1. Remove all USB devices such as printers, mp3 players etc etc.
2. Remove the power-cable and the battery
3. Press and hold the power button for 30 seconds
4. Put the power-cable back in but not the battery and none the USB devices.
5. Turn the computer on
from my experience this might be one of two things...
if it's shutting down while you're installing windows, i'm thinking you might have a problem with the motherboard channel for your CD drive. i saw this happen to a computer at work - we couldn't install windows because it cut off halfway through and blue screened on us.
it might also be a case of a bad hard drive, if you have any testing utility like drive fitness test i'd give that a shot. it sounds like a new one, but they're bad out of the box sometimes.
does the fan work ok? and do you have a laptop holder for it or you just have it on a desk ....get a laptop holder for it if you do not have one and as for the rest goto the power mangment area on the computer and see if the monitor might be on stand by after a few min ...
