Low FPS after reinstalling windows.

Probably a driver issue. I never trust those websites that claim to be able to install all your drivers, just get them from the motherboard manufacturer. Do you have a graphics card (you didn't list it), I doubt that you were getting 250+ fps on the integrated graphics. If you do, remove whatever drivers you have installed for it, use DDU (google it), then go to either NVidia or AMD's website (depending on your card) and download the drivers from their support page.

You're welcome, glad to hear it's running much better. Just as a side note, you may want to go to your motherboard's manufacturer and download the correct drivers from them....or at least keep it in mind if you start getting other issues.

Antivirus: set for "multimedia mode."
This prevents updating from interrupting your media. If you do not have an antivirus with this feature: get a different antivirus.
Set ALL updates to: manual. This prevents an update from eating resources that you would otherwise be using.

Free antivirus from internet: I do not recommend that you install any "free" security tools.
I do not recommend installing "cleaner," "sweeper," "driver helper,"or any free junk from the internet.

Avoid any download which claims to "fix" your computer.

I recommend that you use a professional all-in-one security application - not a free download.

Please consider, when you install multiple security programs, they can conflict with each-other. That's why you should use "all-in-one" professional security.
