i have an Asus p8z77-V LX2 board, bought from this site in a bundle deal.

anyway, recently went from windows 8.1 back to windows 7 (i reinstalled the board drivers from the cd) and now most of the usb connectors won't detect my mouse or keyboard (corsair k50/m30), only 2 out of 6 at the back will detect my keyboard and i have to run my mouse through the keyboard. whenever i connect my mouse or keyboard to other connectors (including front panel) windows says it can't be recognised.

is there some quick fix i'm missing somewhere?

Check the Asus support webpage for your motherboard and D/L the drivers from there, making sure they are the Windows 7 version. Let us know what happens.
 
so i downloaded the usb3 drivers from the asus page, nothing has changed.

this is what my device manager looks like, is this right?
 
Long shot but try uninstalling all the usb things in device manager then when you reboot after hard shutdown it will redetect them and reinstall drivers...long shot....

uninstalled both USB Root Hub (assuming they're both responsible the USB ports at the back on the motherboard, as my mouse and keyboard died straight after uninstalling both), hard booted and the other ports still won't recognize my mouse. cheers for the suggestion though buddy :)
 
the mouse lights up briefly when i put it in any port other than the usb port on my keyboard, then it instantly dies and windows says it can't be recognized :/
 
so usb drives not working in bios? ie put pen in and it doesnt show as being there in bios?

If so then sounds like a hardware prob with the mb :(
 
well, i'm not sure, windows won't detect the usb pen so it could be a windows problem? i've tried like 3 different usb pens and they all light up briefly then die, just like the keyboard/mouse
 
but i agree it's sounding like a board fault. great. really wanted to buy another one.

pretty sure i've had it for more than a year too, sigh
 
Are you sure its only a 1 year warranty with it?

Seen info to suggest some asus are 3 year?

I know gigabyte one are/were when i bought mine.

You need to use the BIOS to check. When you go into the BIOS, you're not in Windows. See if the USB mouse will work (if your motherboard BIOS supports mouse operation inside it). Make sure to test USB 2.0 ports like this, as well as 3.0.
 
i went into the bios under boot options and it showed all 3 usb pens that i'd plugged in (1 at the front panel and 2 at the back).

so windows is the problem? i was also having problems with updates too.
