I’m not sure what else to suggest. My knowledge has come over the last 10-15 years from building my own and my family and friends gaming PC’s, and making game mods (mainly race car livery skin mods
for Wreckfest and Project Cars 1&2 , and truck and trailer skin mods for Euro Truck Simulator II). All my knowledge over the years is self taught through trial and error, and not through being taught.
I think you might have to find someone on a PC forum that could probably help you. Out of the millions of people that have gaming PC’s, you won’t be the “only” person in the country to ever have had that problem. All you need to find is someone that knows the main cause, or at least of had the same problem and found out how to fix it. The best place to find the proper PC experts is on all the PC forums on the internet. The audience to read and hopefully answer your question will be a lot bigger with a wider knowledge of PC programs and PC hardware, what clashes with what, and what happens if something goes wrong. With this specific game furum site, your audience will be this games players only and a much smaller audience, where maybe none of them have ever had this problem before.
