Hello, i have two problems.
1) One of my RAM slots doesn't work. Both of my memory chips work. I swapped them. My laptop detects only 8GB memory.
2) My monitor works incorrect. When i apply 144Hz, bottom half of the monitor turns black. But 60Hz works perfectly fine, and another monitor works fine. GPU is not the problem.
Both problems occured unexpectedly in the same time.
