blue screens slowed my computer drastically

[completesucc]

Recently I ran into a BSOD loop which made me restart my computer many many times by hand because sometimes my computer froze instead of showing BSOD, now after I managed to fix it my computer is REALLY REALLY slow, tried so many things
chkdsk /f
sfc /scannow
removed hiberfil.sys (to clear some room on my SSD)
used Ccleaner
used avast anti virus scan (quick)
used avast cleanup premium
Manually changed my virtual memory capabilities
For context my BSOD error was caused after I ran the driver verifier which triggered the 0x0c4 blue screen
Fixed it by removing Riot Vanguard from my computer with a special programs because windows remover couldn't do the job (my pc froze every time)
I will really appreciate any help and feel free to ask questionss.

Did you remove the special programs and all others not needed?
Start--services, and see what is running in background.
Always can restore to pre-driver install.
