again, this time no matter how many access numbers are not useful. Think of the use of the modem three or four years, may be the longevity is sleeping, so decided to buy a new modem the next day. Evening reading the newspaper, family suddenly a voltage instability caused my attention, I suddenly think of this computer PS2 keyboard interface will often appear contact bad situation, will have something to do with this? with doubt, I took out the tool

: 1. The CMOS parameters are not set to open for a friend who has never used a USB add-in, it is possible that the system cannot detect a USB hard drive even if the driver is properly installed, mainly because the default CMOS port on the motherboard is turned off. If it is not set to open, Windows naturally cannot detect the removable hard drive. To solve this problem, we can reboot, enter the CMOS Setup window, and in the "Pnp/pci CONFIGURATION" column, "Assign IRQ for USB" is set to "Enable

USB connectors on your computer to work properly. Analysis failure: From the phenomenon, the USB device and motherboard interface are not damaged, suspected to be accidental power loss caused system setup error. Problem handling: Enter the Add and Remove Hardware window from the Control Panel, remove all USB devices, and reinstall the USB device drivers that you need to use. Restart the computer, U disk and other USB devices plug in the original fault interface to work properly. Unrecognized

To solve this problem, we can reboot, enter the CMOS Setup window, and in the "Pnp/pci CONFIGURATION" column, "Assign IRQ for USB" is set to "Enable", This allows the system to assign an available interrupt address to the USB port. 2.
