I have been struggling with an issue that presented itself around two weeks ago. Until now my PC has been running perfectly ever since I built it around a year ago. All games I played on it have ran very smooth and on high settings. But now my PC has been crashing whenever I play a game. My PC doesn't completely shut off, all the lights on my keyboard and mouse are still on and the PC power lights are on, but the monitor turns to a blank colored screen and the audio glitches out. At first, people recommended that I should get a new PSU, so I did. But that did not fix the issue. I am getting increasingly frustrated because my temperatures are good on both GPU and CPU, all my CPU cores are unparked and all of my drivers are up to date. Suggestions and help would be greatly appreciated.

My Specs-
GPU: AMD Radeon R9 270x
CPU: Intel Core i7 4790k
RAM: 16GB Corsair Vengeance GDDR5
PSU: Corsair CX600M 600 Watt PSU
Motherboard: ASUS Z97-A
OS: 64-bit Windows 10
Hard Drive: Western Digital Blue 1TB SATA 6 Gb/s 7200 RPM 64MB Cache 3.5 Inch
