Windows Explorer randomly starts to lag and lags other programs until the pc or explorer.exe is restarted.

i reinstalled windows last week due to file corruption and have been having an issue thats driving me crazy as despite trying a ton of fixes i cant seem to fix it. The windows explorer will somewhat randomly begin to lag and lag bleeds into certain other programs. It seems to trigger "mostly" while doing things that directly effects the the explorer like looking through folders, moving files, changing the theme etc. When it occurs the explorer loads very sluggishly with things that used to take 1-2 seconds taking 5-10, TEW 2010 (Text & Pic based game) menu takes 10-15 seconds to go between menu pages and it makes the start menu feel slow sometimes. At first i thought restarting the pc is the only way to get things back to normal, but i then found restarting the explorer via task manager also fixes albeit short term (could be 20 mins or once i made 25 hours between episodes). The only way i've found to completely avoid the issue is ending the explorer task and working without it. During the episodes i've checked the task & resource managers and everything looks fine despite it feeling like the disk is at 100% usage. Also during one of the episodes i ran 3 different hard disk benchmarks (HD Tune, Crystal Disk Mark and Performance Test 10) to see if its my HD failing and they all looked fine and say my s.m.a.r.t. is healthy. 

Before the reinstall this issue would happen from time to time, maybe once a month if that. now it happens multiple times a day. last night it happened 4-times in 4 hours.

Also originally i thought the Corsair ICue program (for my k55 rgb keyboard) was causing as that also caused a similar kind of lag while it was running which is weird as before the reinstall there was no issue. But even after it was uninstalled the issue has remained.
