Thanks for your answer, have posted history but, I have no access to the BIOS setup either with PS2 or USB. It did work with USB, or rather it started windows xp and ran ok with keyboard and mouse, but from pressing the boot button to windows activating, the keyboard is not operational. With the 2 explanations you may have an answer, I think the Mobo is faulty in the PS2 connection area, which is a pity as when working with the USB keyboard/mouse was quite a reasonable bit of kit. However, resetting the BIOS has removed that so its dead bacon at the moment.

Re: POST/BIOS does not find keyboard
I do not recall one ever doing that either. Why couldn't you get into the BIOS to check to make sure that the settings are on for USB. I do not understand why you can't get into the BIOS. That is the way that I have always done it. Strange how it can boot into windows. You must have the settings set so it will boot up without user name or password. I have been doing computers for six plus years and I do not understand that one either. I am exhausted with solutions at this point. I am sure that is not the answer you wanted but I am as stumped as you are.

Shut down the computer and disconnect the USB keyboard. Connect a PS/2 keyboard to the PS/2 connector port on the rear of the computer. Enter bios restart your computer you will see a certain to press to enter set up usually the Delete or the F2 key this will vary depending on you computer and bios. Wait for the main BIOS setup screen to appear. Press the right or left arrow keys to move the cursor to the "Advanced" or "Advanced Settings" menu option. Press the "Enter" key. Move the cursor to the "Integrated Peripherals" or "Peripheral Configuration" menu option. Press the "Enter" key. Press the down-arrow key to navigate to the "USB Controllers" option. Press the "+" or "-" key to change the menu option to "Enabled." Move the cursor to the "USB Legacy Support" or "USB Legacy Function" field. Press the "+" key repeatedly until the value option changes to "Enabled." Press the "F10" key to save changes to the BIOS settings and exit the setup utility. Wait until the computer begins to restart and then press the power button and hold it for approximately four or five seconds. The computer shuts down completely. Unplug the PS/2 keyboard from the computer and set it aside. Reconnect the USB keyboard restart the computer. As soon as you see the initial boot screen, tap the "Delete" key several times and wait for the BIOS setup screen to appear. If you are able to access the BIOS setup screen with the USB keyboard, USB support is active in the BIOS.
Enable PS2 & USB in BIOS You can enable PS2 and USB settings in BIOS by entering the BIOS setup screen when the computer boots. You will need to changes to the appropriate settings in this screen. The exact procedures vary by system, but there are a few common methods that may work if the motherboard manual is not available for guidance. The general procedure is the same for any modern computer system, but the menu arrangement and keystrokes to enter the setup program can vary greatly from one machine to the next. Power on or restart the computer and watch the initial boot screen to find the keystroke required to enter BIOS setup. This is often shown at the bottom of the screen. Typical keystrokes include pressing the "F1," "F2," "F9," "F10" or "Del" key. Press this key when the prompt appears on the screen. You can find the proper key in the computer's motherboard manual or on the website of the motherboard or computer manufacturer. Enter the BIOS setup screen and look for the "Advanced" or "Onboard Device Configuration" menu. Use the arrows to select your choice and press "Enter." Change the settings for the PS2 port by moving the menu choice to the "PS2" setting. Press "Enter" to bring up a smaller menu with the options to enable or disable the PS2 ports. Select "Enabled." You can also use the arrow keys or the plus key to change the current selection from "Disabled" to "Enabled" in order to enable the PS2 port. Change the settings for the USB port by moving the menu choice to the "USB" setting. Press "Enter" to bring up a smaller menu with options to enable or disable the USB ports. Select "Enabled." Alternatively, use the arrow keys or the plus key to change the current selection from "Disabled" to "Enabled" in order to enable the USB port. Save the settings and exit by pressing "F10" or using the "Esc" key to back out of the current menu. Choose to save and exit from the main menu if needed. Follow any additional instructions on the screen to save or navigate the menus. Hope this helps.
This sounds very much like a faulty motherboard if it continually reboots. Try accessing the BIOS using the F8 key, however check you manual to make sure your motherboard uses the F8 key. If you can access the BIOS, it would be worth doing a complete reset to factory defaults and see if this fixes the problem. If you cannot access the BIOS, then you will be looking at a new motherboard.
Hi there. Get the PS/2 keyboard and go back into the bios, make sure all the USB controllers are set to "enabled", save the changes and exit the bios, the computer will restart and your USB keyboard should now work and you will be able to access the bios using the USB keyboard.
Often times this happens when using a USB keyboard / Mouse.
Or when using a USB keyboard through a PS/2 Converter.
Try using a PS/2 Keyboard if available (Small Round connector with a small amount of pins, similar to a S-Video connector.)
Also. Access your BIOS settings and assure that you have Legacy USB keyboard support. Depending on your computer the BIOS / Setup Menu / Options Menu/ Etc. can be accessed by pressing the following key during boot: F1 F2 ESC DEL F12
Let us know your setup(KB and Mouse Port type), and if you have any other issues.
Here is Some Hints to solve your problem.
1.Check the Bios your PS2 ports are enabled,if disabled enable it.
2.Go to the device manager see your PS2 keyboard Driver enabled or not.If disabled enable it.
4.Finally Check your computer with new keyboard.
if all these are correct... you still have a problem
Deffinately there may be a problem with PS2 port of your computer motherboard,Then only one option is remaining, you can use USB to PS2 Converter Cable,Or a USB Keyboard.
If you have any other query post a comment with more information regarding the problem.I will try to assist you more accurately
I have seen this before, and the best answer I can offer you is some Motherboards are better than others when working with usb devices while no OS is in place. I actually tried using usb / to / ps/2 adapters and it still would not recognize the usb keyboard in a couple of instances. I had to get a ps2 keyboard for the installation of windows. After windows was installed I hooked up the usb keyboard and it worked fine. (just speaking from my own personal experience here)
Sorry I do not have a more technical answer for you but I'm almost 99.9 % sure this should work, providing there is no problem with the ps2 keyboard port on the Motherboard. I have never failed to install windows unless there was another hardware based issue of some kind, but never a problem with a known good ps2 keyboard.
Just double check everything is seated properly and try to get into the bios setup, if you cannot use the usb keyboard for this, you can try the usb / ps2 adapter, but if that doesn't work either then use a regular ps2 keyboard. That should work fine, then after setup is complete, windows is installed, then your usb keyboard should work fine.
Did you go into the BIOS and set it to recognize the USB Keyboard after you reset the BIOS? Is windows not noticing it or the BIOS. You stated that it recognized the USB keyboard and then said that it did not. What does all of this mean? USB keyboard does not activate "del" setup.
If it does not work, it is because you reset the BIOS and did not change the settings back for the USB keyboard.
