Approximately 2 weeks ago, I started having issues with sandbox games, Flash Player, and Firefox. The first problem I encountered was the inability to use my mouse wheel to zoom in and out. As of yesterday, games have become completely unplayable. They slow down to the point of freezing solid, and I must use Task Manager to get out of it. I tried multiple Firefox based browsers, all with the same results. I tried uninstalling and reinstalling Flash Player, this did not help. I also tried Chrome, but Pepperflash has always been unbearable. For Chrome, I uninstalled Chrome entirely, then reinstalled it, and this did not help. I "refreshed Firefox" in the troubleshooting guide - and this helped for a while, but the issue immediately returned after closing and reopening the browser. I do not know why. I have not changed anything. The only thing I do with this computer is Flash gaming. I have no other addons or plugins besides ABP (for blocking ads). I have contacted the game companies, I have contacted Adobe, and now I'm contacting you. Something is wrong. I am not alone here. I frequent a gaming forum where players are telling me they have these same issues. I do not know where the problem is, but I don't know what else to do but tell people it's an issue, and hope it gets fixed. So here I am. I do have a low end PC - 4Gigs of ram, 1.99Ghz Quad-Core processor, windows 8.1; but it mostly worked fine on Tuesday (just the zooming issue). I will try any troubleshooting steps you give me that I have not already tried.
