Yesterday I decided to open my laptop and apply thermal heat due to the temperature. However, after applied the thermal paste and put everything back on, my laptop won't turn on. I applied the thermal paste on two spots were CPU and Nvidia chipset.
Its only showed me the lights indicated that the power was plugged in. I didn't hear any beep sound and I'm not sure if the HDD was running or not
Please help...
p/s: i have a Asus G51J

Where, exactly, did you apply it? It should only be between the chip and the heat-sink. And only the very smallest amount should be used since it does not conduct heat very well.

I applied it between the chip and the heat-sink, and also, when I open the laptop while is running, the graphic fan didn't run for some reason...

Taking a laptop apart is complicated. There are lots of small plastic parts and tiny screws. Everything must be connected again exactly as it was. I have no idea how would even turn a laptop on while it was apart.

Double check every single connection. It's also possible you shorted something out while you were disassembling it. You removed the battery when you were working on it, right?
