HI

I am getting frequents black screen of deaths.

Very few times, what we see is Black screen while working on After effects or browsing internet or watching movies, to day I got 2 black screen while playing multilayer MW3.

What it does?
The screen goes black and CPU is running. Keyboard lights goes off.
1 in 10 times I see that whole system gets restarted again.

Graphic driver is latest updated.
CPU temp are 30-34 C idle and 45 C while playing games
Mobo temps around 38 C normal, 50 while playing games.
RAM are okay in MemTest.

I recently tested my system with Performance test with all test and it shows result as 2022.4

What can be the issue of black screens?

I checked my CPU it has black lines.. See images.
I tried to rub it with cloth and it was getting off, is that dust? Will that effect? If yes, then how can I clean it in a better way? Is this CPU is issue?
