Flash player detects the reboot, but not otherwise

I saw one with a MS vista home premium Acer 4710. The USB ports are not detect any hardware (printer & flash drives) when I plug while the system is turned on.

However the system reads the flash drive when I reboot the computer with the drive of fash already plugged. This means that the USB ports and other devices are working properly and it's a software problem. I reinstalled the whole software with the acer system recovery tool and updated to the factory settings. Please help me to solve its too urgent because I'm leaving on a trip.

!!!!!!!!!!!! PLEASE SOMEONE HELP ME!
