Crashing Desktop and Can't figure out why

My Destop has been crashing since earlier in the year. I've tested the ram, bought a new power supply, and bought a water cooler for my cpu. It happens very randomly and it will go straight to a black screen. I don't think it is an overheating problem. Graphics drivers are up to date and I believe the Bios is also up to date. My thought is maybe hard drive but I need advice anything would help.

Thank you, Forrest
