My pc crashed cause it overheated, so I decided to dust my pc and apply new thermal paste to the cpu. But since I've done that, my pc keeps shutting down immediately everytime I turn my pc on.

I assumed that I didn't mount the cpu heatsink/fan correct, so I've tried to remount it a couple of times, even applied new thermal paste.
But this didn't work.
The pc keeps shutting down before even getting to windows.
I think it's probably the cpu overheating that causes my pc to shutdown everytime, but I don't understand why it's still overheating.

Hope someone can help me.
