Ok so here is the story.

I have a HP Pavillion ZE4900 Laptop. I've had it for ehhh 3 years.

Reciently it was overheating alot, thanks to my geek buddy i realized my fan wasn't working. After calling a few places and getting quoted too much money i decided to take matters into my own hands.
Sooooo i took my laptop apart (BIG pain in the ass) The fan was so full of dust, and thanks to my beautiful Bella... cat hair. So i clean it out, compressed air and all, put it all back together ( with the exception of one screw i can't figure out where it goes. ) I turn the computer on, and it seems fine.
15 min later, it dies, the fan wasn't spinning.
So i go to Circut City... i got a targus notebook chill pad. Works great. All of a sudden my fan starts to work again.
So now, with the fan and chill pad my computer is doing fabulous.

OR SO I THOUGHT!

Yesterday i was online and i got a blue screen that said something to this effect:
( BLUE SCREEN )
It says something about if this is the first time restart the computer, which is stupid because it doesnt let you restart, and it restarts on its own.
Beginning dump of physical memory.
Physical memory dump complete........

It happened last night for the first time. Then i was watching a movie and it did it again. At this point i just shut it off.
This morning i put the computer back on and other then my active desktop needed to be restored it looked fine.

anyone?

reformat your harddrive, back up all your work before you do it. Basically whats happening is your harddrive has corrupted sectors on it, which intern will be read and stored on your ram chip. Then your CPU goes to read your RAM to pull up the information for (insert application here) and says "WTF IS GOING ON???" trys to read the sector again from the harddrive and says "OMFG WE GOTS A Hax0rs" so then your computer is forced to dump its physical memory (on the ram chips) and restart to clean them out. You might want to scan your harddrive for erros before you do do a reformat tho, might fix the problem. Start -> Programs -> Accesories -> System tools -> Disk Defragmenter. This will scan for errors and also move files to the front of your harddrive so they can be located quicker and easier. Anywho, hope this helps.
