Multiple program crashes

I dont know where to post this as Im not sure if its hardware related.

 

Yesterday I applied new thermal paste and cleaned the PC . Directly after that I started getting crashes eg FSX,firefox, Running vector tool CTD

 

So I restored fsx -se from 3 different back ups and all 3 are crashing which makes me believe its a hardware problem so I tested the RAM sticks separately and Im getting the same crashes on both Ram sticks however memtest shows them both okay. I tested my 2 SSD's with crystal and they are good

 

I dont have a clue whats going on..

Im going to put a hold on this topic. Removing and swapping around the Ram sticks may have fixed the problems. Im doing more testing but so far so good
