Thanks for your continued help! I really appreciate it!
If I do get the money to buy a cable for testing purposes, which cable exactly should I buy? I know nothing about cables or monitors.
I'm not sure what accessibility software is. So, I don't think I have any?
I haven't had the chance to do a repair install of Windows yet. But I did follow the instructions for playing in a clean boot. I followed the guide exactly (triple-checked to make sure I didn't miss any steps) and I remembered what you said about leaving EABackgroundService enabled. However, things didn't go quite the way the guide said they would.
There were some programs that simply would not disable. Sometimes I would hit "disable" and it would disable for a fraction of a second, but then re-enable. Then, when I hit "End Task" a pop-up would come up saying "This task cannot be ended." The programs that caused me these problems were McAfee, Dropbox, and a BUNCH of Windows programs that I've never heard of.
When I tried opening Sims 4 in the clean boot, a little black box came up saying "Preparing game..." with a loading bar. There was a weird clicking sound for a couple seconds that sounded like it was coming from my CD drive, as if it was trying to eject a disc. It never loaded the game; the pop-up just sat there until I ended it via task manager. When I tried opening the EA app, it said "Background services crashed. The background services aren't responding, so we're kicking off the update manually. Stay Put while we get the app up and ready for you." Then it gave me the option to Run Update or Cancel. I chose Run Update. A big black screen came up saying "EA is already working...closing screen in 4 seconds." And it counted down and disappeared. When I tried opening the EA App again, it just brought up the ""Background services crashed" pop-up again. This time, I hit cancel. I tried to run Sims 4 again. It brought up the infinite "Preparing game..." bar again that stayed there until I hit End Task via the task manager.
Next I tried to follow the instructions to reset the computer to restart normally. The guide (which I had open on my phone; I never opened any browser while I was in the clean boot) told me to go to the General tab and select Normal Startup. Did that. Then it told me to go to the Services tab, uncheck the "Hide all Microsoft services" box, select Enable All, and then hit Apply. However, when I went to the Services tab, the box was already unchecked and everything was already enabled. Which doesn't make sense to me because, when I was preparing the clean boot, I DID check the box, I DID disable all, and I DID hit Apply. But for some reason, it auto-reset?
Anyway, I followed the rest of the instructions for rebooting the computer normally, and I think everything is back to the way it was before I did the clean boot.
I just tried opening the EA App again, and it opens normally. And I just tried opening Sims 4 and it did the same old thing of showing the logos and then auto-closing.
