USB functionality turned off in BIOS

I went to use my AK32VN system recently and at startup BIOS stalled at what looks like a dianostic screen with a blinking cursor. After using this system for more than a couple years this was the first time I'd seen this screen. It listed all the vital specs of my machine but BIOS stopped there. It did not respond to any keystrokes and I eventually had to reboot.

Going into the BIOS menus I found that if I enabled USB functionality under Integrated Peripherals it caused BIOS to stall at this particular screen. If I disabled the functionality then startup works as it should, Window2K boots and everything is fine, except that I no longer can use my USB devises.

I'm a graphic artist so I can't do without my Wacom and scanner. I haven't installed any new devises or made any modifications so I'm puzzled as to what casued this switch in settings. Is this a sign of age? Is there a workaround that I can use to enable USB and make the system boot as normal? Or is it time to replace the old girl?

Re: USB functionality turned off in BIOS

I had this same type of problem - and it turns out it was my fault. In my case I have a Dell 24" ultrasharp monitor, which has a USB hub and 4 ports, as well a a number of media reader slots. I had taken some pictures, then plugged the flash SD card into it's slot - and forgot to download the pictures. So I shut down for the evening, and when I tryed to boot the next day, the machine stuck at the bios screen.

I went so far as to swap out my mobo, but when the problem reoccured, I knew it had to be something else. Then I noticed the flash card, removed it, and the boot went fine.

So, do you have anything new plugged into any USB ports?

Worst case, though, if the machine boots properly when some or all USB devices are not connected, you can still connect them after the machine boots, and they should still function.

Disk boot failure

Your hard drive is missing from the system. Or, just does not recognize it. The obvious - Remove any USB devices like drives and any media from disc player. Its trying to load, but can't find bootable hard drive, CD, or USB... Remove the hard drive and re-seat (reconnect). Check BIOS by pressing an F key during boot. Look on the screen for correct Function key. Might be F2 key. Verify BIOS recognizes the drive. It must be listed! There is no going forward if it's not. Check boot order and make internal hard drive first. Save and restart.

Biostar GF 7100-M7s no post screen

You have made the same mistake that I and many others have made before you....making too many changes at one time. It makes it difficult, if not impossible, to know which, if any of the changes is the problem. That being said, I'll try to help. First, did you reposition the BIOS DIP back to the proper position? Otherwise, the BIOS is held in reset and cannot work. I would, for now remove the new video card and re-attempt using the onboard video. This removes one potential problem. Try that and see what happens.

The motehrboard bios doesnt boot from usb to install windows, how can i update the bios to boot from the usb?

Insert your USB jump drive into a USB port on the computer containing the bootable program. Copy the information to your jump drive, then insert the drive into a USB port on the computer you wish to boot the program from.

Power on the computer. When the computer begins displaying its startup information, hit the key indicated on screen to enter the computer's BIOS (the "F1" or "Delete" keys are commonly used to access the BIOS).

Browse through the menu options in the BIOS to locate the computer's startup and booting options to locate the "CMOS" menu, which is where you'll have the option to set which devices will boot at startup.

Browse though the list of bootable option---they'll be ordered as "First Boot Device," "Second Boot Device" and so on. Set the USB jump drive as the first bootable option---your BIOS may refer to the drive as a "USB Removable Floppy Disk."

Save and exit the BIOS. When your computer restarts, your program will boot first before your operating system.

My computer says there is no disk or please insert disk

disk, are you referring to a cd/dvd disc or are you reffering to a harddrive disk??? If you are reffering to a harddrive disk, then your hard drive is either damaged/ or inproper loose connection or if it s usb/network disk, make sure it is plugged or configuration is changed in the bios menu. If this is a harddrive disk, and after POST or startup, it is giving you this error message, then before we pressume it being damged, check in your bios menu to see if the bios reconized the hard drive disk, if not, your hard drive is damaged and needs to be replaced.

Boots to a blue screen but does not recognise the keyboard you have the option for esc f1 or f10 but unable to do anything since you can not use the keyboard. I have tried a usb and ps2 keyboards

As per your description, if I am not wrong, your bios screen comes ok but the blue screen comes when the actual Operating System loads.

This shouldn't happen with a PS2 (the green round pin - to be fitted in green socket only) keyboard. If it does, then you have problem with the motherboard.

But, if you have a USB keyboard, try putting the keyboard in bottom part of USB(Port 12 - as shown in the picture), next to VGA connector.

You may also need to enable USB Keyboard Support from the BIOS - which can be done by pressing "Del" key at the startup. - and save it by pressing F10 - and exiting BIOS.

Hi, I have an old Acer Aspire desktop that I am working with, it originally had Windows 98 and the two USB ports on the back were not functional, I upgraded the operating system to Windows 2000 in hopes...

You have to install usb drivers for win98 and win2000 operating system.
But if you install windows xp usb drivers not need because winxp recognize usb device as plug and play.
Windows xp is fast and more flexible than win98 and win2000.
click here

click on above link and download usb drivers for win2000.

Sound card

When you turn your computer on look for a key to press at the startup screen. It could be delete, escape, or F1.

Once you press the right key the BIOS setup screen will appear. Look for the audio settings in the control panel and make sure there enabled. Save the BIOS settings and restart your computer.

Windows will detect the sound card and attempt to install the drivers.

Update my Intel D845GVSR Bios Version to VA84510A.86A.0056.P20, then my USB driver is not working at all.

I followed the suggestion of changing the BIOS configuration to the recovery mode, however one thing was missing - it required a startup disk and I didn't have one. I then changed the BIOS configuration to the config (pins 2 & 3) mode, booted up and went to the BIOS/CMOS setup and a new menu tab appeared called "maintenance". I went to the advance tab and selected USB configuration and, instead of a blank screen, there appeared a selection for USB support and it showed disabled. I changed the setting to enabled and three more lines of information regarding USB came up, but required not further changes. I went to F10 and saved and exited and I now have me USB capability back.
