CPU Overheating, How great is the damage?

Short version{
I got blackscreen due to overheating when I played a new game. I checked and cpu temperature was at 98 degrees C. Now when I play my old games, I also get the Blackscreen problem(Temperature at 85C).

I currently think my cpu might be too damaged to play any of my games and will need to be replaced. But could there be other complications/things to keep in mind?
Could other components be damaged?
Or could it be another problem altogether?

Long version{
I got “ME Andromeda” recently and found that my long running problem with low RAM finally became too much, so I upgraded from 8 to 16 Gb. Fast Forward one week and suddenly when I start playing, within 10 min my screens go black and I get the distinctive windows message bleep. Audio continues for about 10 seconds before also quieting down, and my screens shuts down due to not receiving any signal.

I lost connection to my gpu after this, but that is a normal problem for me and I fixed it without too much problems(the card bends over time and I need to twist my computer from time to time).
So I started the game thinking all was well, but it continued to happen. After searching for solutions I came across the tip that It could be overheating, so I checked that with the Open Hardware Monitor and found that temperature(processor) rose to 98-100 degrees C when I played the game(it’s 40 degrees C at the time of writing this).

To further test temperature I tried playing some Heroes of the storm, which I have always been able to play without the slightest sign of problem. The temperature turned out to be at aproximetly 85 degrees C when that game was running. And after about 16 minutes of this I got the Black screen problem again.

Final solution{
I changed the thermal paste, this caused the temperature to go down, but I still got blackscreen. I then reinstalled my grapic drivers again and after that temperature have been at safe levels and I'm yet to recieve any blackscreens.
