[SOLVED] How do I take off my cooler master heat sink?

[ooft123]

So I have had this PC that my father built for at least 3 years, but over the past year or so I have been getting insanely high cpu usage (100% in every game) and in general the computer has been quite slow. About 6 months ago I purchased some thermal paste just to see whether that would fix my problems but I realised I couldn't actually get my heat sink off of my cpu. It is a cooler master heat sink (apologies I cannot recall the actual model) and I read somewhere else that I need a right angled screwdriver or something to take it off. Any suggestions on how else I could do this?

Specs

GPU: GTX 1070
CPU: i5-6600k
Mobo: Z170M plus
RAM: DDR4 2133 MHz
PSU: Gold standard PSU (I can't remember the model but its fine I think)

I'll also add that my cpu is so bad right now that it goes up when I wiggle my mouse from one side of the screen to the other by at least 20%. When I am on google it is on around 50%....

Depends on particular cooler but with most you need to unscrew 4 screws holding to to MB, wiggle it left to right to break seal and than you should be able to gently take it off.
