Question Why is my computer so slow after reinstalling windows

[VirusKilledMyPC]

so i recently got a virus on my computer that may or may not be relevant to my issues. So to get rid of that virus i reinstalled Windows 10(please keep in note i have the updated version)and i don't know why but my computer would open things very slow even though cpu and disk usage would always be below 10 and my ram usage would be below 30.(Normal Usage)
I have a FX 6300
GTX 750
8GB single channel ram
am3+ Motherboard
500w power supply
ANY HELP WOULD BE MORE THAN GREAT!!!

Did you go to the motherboard product page and install all of the relevant motherboard drivers after reinstalling Windows?

Did you go to the AMD website and download and install the proper chipset drivers for your motherboard?

Did you install the latest Nvidia drivers for your graphics card?

Have you run extensive virus and malware scans AFTER reinstalling Windows, on ALL drives, to ensure there is not still an infection?

you should have not installed windows 10 first but rather an antivirus or malwarebytes, I recommened avast antivirus and If your pc is running slow go to "System", then go to "Advanced system settings", then go to "Performance" and uncheck most boxes, you should only leave "Show thumbnails instead of icons" and "Smooth edges of screen fonts" this will kinda optimize your pc, and you should also turn Sysmain or as it used to be called superfetch, go to services and disable it is known to cause high disk or cpu usage.

Keep in mind that if/when connected to the internet, some systems are often quite busy for several minutes to an hour pulling in yet more precious Windows updates....

And that is the third thing that should be done, after all drivers are installed, is to run through Windows update until there are no updates left to do.

And you can take a closer look within Task Manager and Resource Monitor to observe what your system is running and doing while being slow.

Some app or process causing a bottleneck.
