Monitors Black with Fans at Max speed w/ PCU/PCIe Bus Errors

I have had my PC for about a year and half. The past 6-8 months, my pc has been shutting off my monitors and kicking the fans up to max. The only way that I have been able to get it to stop is by holding down the power button. It usually only happens once when I am doing something, but has been doing it more and more often, even happening within 2 mins of rebooting. Usually happens when I am playing a game but will do it when I am on the main screen watching a video. I have tried updating and reinstalling the gpu drivers as well as updated the bios but it has not worked. I did download WHINFO 64 to log my system and was able to get the last crash.
I noticed that the last 4 logs on my system gave PCU/PCIe Bus Errors but do not really know what I am looking at or what could cause this.
Any help is appreciated.
