    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

This has only started happening recently. Happens on all ports and to all USBs - even brand new ones. The PC takes nearly 10 minutes to register that the USB is plugged in - the green strip at the top of the Windows page just keeps going and going. Once it has recognised it, the USB works...
