USB keyboard keeps disconnecting

my USB keyboard keeps disconnecting randomly, and its annoying the hell out of me, i think it may be the usb ports, but i have 10 usb ports on my pc (6 in the back 4 in the front) and i have tried several keyboards in every single usb port and they all disconnect randomly, one turns off after a few mins and doesnt turn back on and i have tu pull the usb out of the port and plug it back in, others disconnect and reconnect within seconds (dadum.....dadum)

i also have a USB mouse and it has no problems at all, and i have a 1tb external HDD that is connected as well, and i have tried with these disconnected and connected and the problem is still there

i have updated all my usb drivers and i am using intellipoint and intellitype, the keyboard doesnt do it in my girlfriends computer or my sisters (both running windows 7)


i have also disabled the option for the "computer to turn off these devices to save power" in device manager

the motherboard i am using is the ASUS P7H55-V

Please help me....

Have you installed any non-proprietary drivers not written for Windows 7 64-bit?

A good example is USB_Lib.sys or something the like used to connect PS3 controllers to Windows.

Did you try to overclock the USB ports, example: USB Polling Rate past 125Mhz?

This messes with Windows USB drivers and also puts Windows in test mode.

If non of the above applies, try restoring Windows system files. There's a way to do it with CMD but I forgot, second method is to use your windows installation DVD and do an upgrade (it will not change all your programs and files).

i have no idea how to overclock usb ports, and i dont even have a ps3 controller, i have updated all drivers i can find and DustSailor i have already said in my original post that i have tried several keyboards in all of my usb ports

Yes but I had other troubleshooting in that post as well. Try typing msconfig and click it. Then click the option on that very page that says diagnostic startup or boot. then click okay and restart the system. Let us know how it goes.

Otherwise, thats about all I know how to do unless you can give some more information on your problem.

not much more info i can give you... it just simply a usb keyboard plugged in... after a while it stops working, or disconnects and reconnects within a few seconds

Go into the BIOS and make sure "Legacy" or however it's named USB is enabled.

Before you start replacing stuff start with the simple..... it doesn't cost to check your BIOS settings first.

checked bios and usb keyboard is enabled... my motherboard is still under warrenty to if it is a faulty product it wont cost to replace it, also i went into diagnostic setup and it didnt do it
