The problem now is Prime95 is causing BSODs. That has nothing to do with EA games. It just may be coincidence that the problem EA games are pushing the OPs computer as hard as Prime95 is.
The only computer that I have ever had where Prime95 caused it to BSOD had a failing component.
Again, if only EA games, per title, are the problem, then that's where one should look - the EA games.
And Prime95 is nothing to be messing with "if" you (the OP) is already running an unstable system.
I've tried EA forums/Support. Seems to be an issue with FIFA some people experience and nobody can really pin point it. I am using the EA Play app as you have to or the Origin App. Yes the confusing part is how I am able to play other games and no BSOD. I keep going back to something in the game/app that just doesn't like one of my components or a driver.
Right. And if a game with a known issue is the problem, why are you chasing other stuff? And especially if you can play other games.
While nothing is absolute, seems to be the game app may be the problem.
As a side note, I had an issue with Tom Clancy's The Division 2 where the game became a crash fest. I couldn't play 10 minutes before it hard locked my PC. I tried a myriad of things to include clean installs, different GPU drivers, memory tests, breaking down the GPU and replacing the thermal paste / thermal pads. Even swapping GPUs from my backup system. Nothing worked!!!
In the end it turned out to be a faulty power supply. That whenever the GPU was pushed (requiring more power) my 1000-Watt Power supply flake out and hard lock the PC. Another tale tell sign of a bad PS was whenever I powered off the PC, the BIOS would reset... no matter how many times I replaced the CMOS battery on the motherboard. Checking the BIOS for voltages told me both my 5 volt and 3.3 voltages were low. I think the 3.3-volt supplies power to keep the CMOS battery charged.
Swapping the 1000-watt power supply for the one in my backup system solved my problems. Since then, no more hard locks and BIOS resets.
Moral of the story.... check the power supply is good. You can check your BIOS to see what voltages are showing. If either the 5v or 3.3v are a off by a few volts - instead of 5v you have say 4.5 or on the 3.3v side, you have say 3.0 instead of 3.3volts, you might have a PS issue.
BTW, because the GPU wasn't pushed during non-gaming sessions, the issue wouldn't appear. And why it was hard to find the cause.
Good luck.
