Coolant...or whatever u call those.

okay....here is my problem...

2 days ago i cleaned my PC's hardware, like motherboard, graphic card, and everything else...

when i clean my gigantic fan and that metallic stuff under it, i notice there is so gray gooey matter under it (on the CPU chip and the metallic stuff above it), and i ignored and thought its just dust, so i wiped it off...

and then when i run my PC, it overheats every 30 minutes and shuts down...

and later i found out that gray stuff is called coolant or whatever material that cools the CPU chip down...now i wiped it...

All I am asking is where i can get those back or buy it..please tell me, i really need to use my PC for a lot of purpose..

My Spec:
Intel Core 2 Quad
2GB RAM
8500 GTX
and some other stuff...

 

That gray goey matter was Thermal Paste or Thermal pad
Without it you'll Kill your CPU..........

You need to buy some Thermal paste, Clean the CPU/HS and re Apply

 

Asus is right on. I like this kind of paste: http://www.newegg.com/Product/Product.aspx?Item=N82E16835100007

Make sure you follow the directions.
