Hey everyone, I just built my own computer and everything was working great but then after a few days I've been getting system freezes where the monitor will cut out and not detect anything plugged into it. Hitting the restart button does nothing, and I have to hard reset the system and everything works again.

I have run multiple stress tests on the system to see if it was overheating, but everything reports back that the max GPU temp is ~80C and the CPU never crossed over 60C. Even while typing this the system did it even though it had be on for less than 5 minutes. I have double checked every connection and they seem to be solid. I have tried updating drivers and re-seating cards. The only thing i haven't done yet is remove the heat sink and check the cpu for damage.

I am completely befuddled because it happens so randomly. It will be fine for hours without a blackout then it can't go minutes without it going down 3 or more times. And it's starting to get really annoying.

I was able to run Deadpool at maximum graphical settings for an hour and leave the computer on over the weekend with no problems, but then I used it for 15 minutes, and it crashed again. I am able to hear audio for about 15 seconds after the video cuts out, but as soon as the monitor goes to no input detected the entire system locks up. Also last time this happened I was not able to turn the system on until the next morning. You're my only hope.

Here is the part list that I used to make this machine
