A couple of neat programs I recommend are speccy and ccleaner. They are both by pririform, if I remember right. Speccy has basic info on your PC, it's good to run immediately after you've closed your game (or during your game if you have RAM to spare, I'm fairly certain it takes up little of this resource) to see if you have any possible overheating issues. If you've already ruled those out, it's just a decent information keeper. Just today I opened it and found out some info about Windows 10 I had been curious about. I'm not sure if ccleaner will help with gaming performance, but it should most definitely help with browser performance and general maintenance. It basically clears out your cookies and other various cached files kept on your computer. In the modern age of computing, cookies are less of an issue than they used to be. Nonetheless they can add unneeded malarkey and nonsense, and ccleaner is a good way of clearing them and other useless files out. It also has a registry cleaner, which I run every so often to see if there are errors in my registry. You can backup the registry with the program, so it keeps your PC running smooth with no real risk. Best part about these two programs is that you can almost never beat free.
