Please do, because the vast majority of us, myself included, are not having the problems that you are, and my PC ain’t got nothing on yours. I have no idea why some people are burdened by these problems when most of the rest of us are not, but I’ve concluded that it has to be something environmental that’s unique, or very close to unique, about your specific installation. You stated that your community folder is empty, the next thing I would try would be removing any overclocks, if you have them, but if you don’t that’s obviously not the problem. Next would be trying to lower your settings, even all the way down to the bare minimum available just to see if you can get up and running at all, and if so, then start raising them until problems happen.
But if you’ve eliminated all of the above “usual suspects”, then unfortunately, esoteric issues like having a memory chip with a bad thermal paste application (which would be a ■■■■ hard problem to try to track down, but it’s real, it happened, and I read about it on this very forum) can also cause such problems. If you have another computer available, you can try installing the sim on there to see if the problems go away, and if they do, then you’ve at least narrowed your culprit down to something in your rig. But if another system in the same household exhibits the same symptoms, then I would start to suspect your Internet connection.
So, I’m going to reverse my initial advice of just giving up and quitting, and see if you can at least narrow it down to your specific computer being somehow the source of your issues. At least then you know that you might have some off the wall problem that’s unique to your system that is the culprit. But narrowing it down from there will be extremely difficult, though I would start by removing RAM DIMMS one (or maybe even better, two) at a time to see if they are the issue. If that’s not it, they I’ve just run out of airspeed, altitude, and ideas all at the same time. But I wouldn’t bother even doing that until you’ve had a chance to ascertain if the problem lies somewhere within your rig first.
Good luck, I hope you manage to find the source of your problem.
