Okay so im troubleshooting my friends computer
Specs
CPU- AMD Phenom x4 965 @ 3.4 stock speed
RAM- 8gb ram @ 1333mhz
GPU- AMD 5750 1gb gddr5
MOBO- ASUS M5A97 r2.0
HDD- 1tb hdd
PSU- Thermaltake TR2 600w
The Problem
Everything within windows runs fine. Initially would blue screen when playing gtav but I've replaced a stick of ram and it no longer blue screens. however gtav will load up and play for a bit but when i enter a heist it will blur over grey and not load. if i continue playing eventually things will start turning black especially at night they go pitch black (cant see a thing). Civilizations V won't start up from steam at all i click the button then nothing happens.
What I've Done
Replaced ram with no effect to the problems (but still could be the ram slots)
Cloned hdd while it was blue screening with no effect.
Currently cloning hdd again to see if that solves the problem
Ran CCleaner and malwarebytes nothing bad found and cleaned up some things
Dust removed and man was it bad; I had to take it outside with a vacuum and 5+ minutes of blowing.
Dont know what to do if this clone fails
Please Help
