Windows Install Slowdown

[Lemlurker]

IDK if this would make a video or some shiz but ive heard from lots of people that they regularly reinstall windows and i did it recently and it really helped my fps, why is this? because now ive gone back to the old install as it corrupted and its stuttewr centeral over here with a 9900k and a 2080. even in light games like overwatch i get hangs and fps drops where i shouldnt, theres no unruly cpou or ram useage going on and no unknown porocesses its just slow and choppy for this install of windows only... any ideas why?

Sometimes if a system isn't well maintained you can end up with a bunch of stuff executing on startup that is accumulated through the years and slows down the computer. If you're using a HDD there's also the problem of fragmentation if you haven't defragged it in a while, which causes disk slowdowns and can cause stuttering or freezes when loading new textures for example.

 

There's also a chance of there being malware on the old installation.
