    Windows 10 USB problems and keyboard disconnect/reconnect problem

    So I got this PC recently, like a month ago. Everything works fine except my mechanical keyboard I used on my old PC. It keeps disconnecting and reconnecting and displays a driver error. It works on my laptop and on my sister's PC and it never disconnected on those devices. I tried updating chipset drivers, reinstalling Windows and trying again, but no success. I'm using some old PS/2 keyboard right now, and funnily enough, it disconnected around two times too but not like the USB keyboard that doesn't work at all. My Logitech G402 works normally, it never disconnected and it's plugged in USB2 port. Tried different ports too, disabled USB3 ports in UEFI, still no luck. Also I noticed that when I plug in my USB stick in the USB3 port my PS/2 keyboard stops working, the led lights (scroll lock, number lock etc.) keep flashing and when I press any key it doesn't seem to do anything. The moment I eject my USB stick it starts working normally. Plus, I today plugged in my USB stick in the USB2 port with the mouse in the next USB2 port too, and I opened Rufus to make a bootable USB, and bam. My mouse stops working and Windows displays USB Power surge error. I hope someone can help me, I'm desperate.

    My specs:

    Motherboard: ASRock H81 Pro BTC
    CPU: Intel Core i7 4770 3.4 GHz
    GPU: Gigabyte GTX 1060 6GB G1 Gaming
    RAM: 8GB DDR3 1333 MHz
    PSU: SeaSonic G Series SSR-650RM 650W 80+ Gold
    OS: Windows 10 x64

    No one knows what it could be?

    well now that you have tested the device in question works ok on other pcs then , there are four main causes to surface issues like yours :

    1 - bad drivers where i suggest you install your manufacturer's chipset drivers , sometimes this is not enough as windows tends to update them back to other glitchy set so maybe you need to stop windows from auto-updating drivers before installing chipset drivers (may require windows pro) .

    2 - loose USB ports / connecting cables , where you should try to examine if the moving cables around or touching the ports during operation may result in a disconnect/reconnect operation , in case its cables then cables needs replacement , in case of loose ports may require being sent to a hardware shop where they might be able to replace the ports or maybe administer some hot air to ports to help re-soldering them (this is not a thing non professionals can do as they may melt other essential components in the process) .

    3 - Blown Capacitors where you need to physically examine the capacitors near the ports area (usually 4 to 6 visible ones) where if their top metal plate appears ruptured , have a hole or curved not straight may require being sent to a hardware shop to be replaced (no pressing blown ones back in wont fix them) .

    4 - PSU has a lose power line delivering pulses of dc current rendering the board to perform randomly where i suggest you have it replaced by another of your possession and see if the problem continues .

    Thanks for the reply. I already tried drivers from the official site and installing them after a clean Windows install. Since I cant get my hands on a new PSU, Im thinking of buying a dedicated PCI USB card and installing it on the mobo. Do you think it will work?
