USB ports/devices stop Working when Windows 7 Boots
I have a HP Pavilion P6204Y Special Edition running Windows 7 Home Premium x64 that has been having issues with the USB ports for the last few weeks.
I am using a USB keyboard and mouse, which both power up/light up as soon as the computer is turned on. They work fine when I enter the BIOS, but as soon as Windows starts loading, the keyboard and mouse turn off and stop working. USB memory stick and any other USB devices totally don't show up at all either, the computer doesn't even notice that a new device has been plugged in.
I attached a PS-2 keyboard and it worked fine and I was able to go to the device manager. I checked and all the USB drivers were installed and reported that everything was working correctly. I uninstalled them all and then restarted the computer, same thing happened again.
I used the PS-2 keyboard again and ran a system restore to 5 days again (May 10). After the restore was done and the PC restarted all the USB devices worked again.
*(This is the second time this has happened now. The same thing happened on the 8th of May and I fixed it with the same procedure.)
