Cant use USBs

Now i noticed for some time that windows "reserves" some ports for some devices...even USBs but it never hurt me when i was working on pcs with around 8 USBs
Now im on a laptop with 4 USBs and i also use an exterior keyboard and mouse
Today after plugging a flash drive 3 of my USBs went down and will not accept any device
Both keyboard and mouse work in bios and work if plugged in the 4th USB ( its the live USB ) but the other 3 will not
I already rummaged through device manager and regedit and found nothing off so please HEPL!

NVM fixed it
first in command line i did "sfc /scannow"...it said something about corrupt files being fixed
then 1 time restart later all was well

You might consider rebooting and running SFC /scannow two more times, rebooting between
Run it twice more even if it tells you no integrity problems were found.

SFC processes things in small groups

After the third SFC, follow Option Three in this tutorial: SFC /SCANNOW Command - System File Checker
