Hello Lately, my pc had high temperature problems, obviously caused by lot of dust, stored on the cpu cooling system. So I decided to clean the mess! I removed the cpu cooling system, the cpu, cleaned everything, and put them back together. I have done this many times, but this time I forgot to apply thermal paste, on the cpu surface. After the power on, I got only fan activity, no beeps and black screen only. I checked the cpu on another pc and it appeared to be dead. I would like to know: Is there any chance for other parts(mobo, vga card, memories) to have been damaged? Also, I have a spare cpu, little slower than the previous, same socket although. Is there any danger to damage the spare cpu, if the mobo is already damaged? Thank you in advance.
