Question PC has problems with multiple games and I can't figure out why.

[SoapWasTaken]

Hey all. I've had my PC for about a year and a half and it's constantly given me problems at random with multiple games. FFXIV will crash on me at random and continually crash until I reset my PC. Lost Ark can crash anywhere from a couple times a day to once a week. I just tried playing Apex Legends for the first time in awhile the other night and 30 minutes in I crashed. Some games are fine but a lot have problems at random. The crashes don't just close the game, they all have error codes for their respective games and I've tried a bunch of solutions offered in threads for said error codes but nothing seems to help. I'm honestly about to just buy a new PC and hope everything works well so if anyone has any suggestions as to what the problem may be from my vague explanation I would really appreciate it.

So what kind of error codes were you getting? Which drive do you use for gaming? Have you checked your event viewer for critical events that coincide with the crashing games? Are your bios, gpu, files up to date? Have you checked game file integrity if they are steam games?
