go into your control panel and look at device manger and look at USB ports i thinks called you might just have to update the drivers for the USBNot detecting keyboard?
Some computers need to have 'Legacy USB' or 'USB keyboard' enabled in the BIOS before they will use a USB keyboard (or a PS/2 keyboard plugged into a USB adaptor).





You will need to find a older PS/2 keyboard with the round purple plug and plug this in. You then need to go into setup as the machine starts (it usually says on screen which key to press to enter the BIOS setup). Usually under 'Integrated peripherals' is an option to enable 'Legacy USB' or 'USB keyboard'. Enable this and you should clear the keyboard error.





If you plug in your PS/2 keyboard and still get the error, you may well have a faulty PS/2 socket which would mean you cannot gain access to the BIOS. This could be a problem...

Sounds like your computer bios is set up to halt on all errors, and instead of looking at the USB port for the keyboard it's looking at the PS/2 keyboard port. When it doesn't find a keyboard there it pops up with the message ';Keyboard error, please press F2 to continue';.





This is a great little problem 'cos without the keyboard being recognised you can't press F2 to get it to continue (who thought up that one!).





A few solutions to try...





Firstly see if you can get a PS/2 to USB adaptor (they used to give them away free with all USB mice at one point, but seem to have stopped doing this, if you got one with you mouse it might be colour green, it will still work with you keyboard just plug it into the purple port though not the green one, and have the keyboard plugged into it, instead of the mouse).





Or see if you have a friend with a spare PS/2 keyboard lying around (PS/2 is the mini-din plug normally coloured purple).





Once you get the keyboard working go into the BIOS and see if there is an option to enable Legacy Keyboard and Legacy Mouse, and change the Halt on All Errors setting to Halt on All but Keyboard.





Or reset the bios on the motherboard - to do this open the computer up and you should find a jumper somewhere on the motherboard marked as bios reset or cmos clear, move the jumper from pin 1-2 to pin 2-3 and then back to pin 1-2 (with the power disconnected - very important ensure mains cable is removed from PSU, not computer just turned off as motherboard can still be live if mains is connected). If you can't find the BIOS jumper see if you can unclip the battery, remove battery wait 5 minutes put battery back in (normaly they are just a standard watch battery with a small clip at one end that pushes up to flip battery out).





Resetting the BIOS should hopefully clear the halt on settings and should allow it to boot, if not you need to find a PS/2 keyboard.
First go and check the status of connectivity of your keyboard. To check right click on MY COMPUTER icon, select PROPERTIES, click on HARDWARE tab, click on DEVICE MANAGER button. It shows u all components and pheripherical devices attached to ur computer. Check the keyboard, if it shows yellow colour on the icon then its not connected properly. Double click on the keyboard to get another window. In general tab it will show u whats the problem in ur keyboard. There is TROUBLESHOOT button click on that it will also guide u how to fix the problem or recognize the problem.
