1415825 2016-02-10 05:02:00 Hello.
i have never come across this problem before until now, i have a USB keyboard and on system startup i can press the DEL key to get into bios but once in there i cant navigate, there are still lights lit up on the keyboard but nothing works. When windows was installed it was navigating in bios.
A masive google search and alot of reading didnt help my situation, i have tried a PS2 to USB adaptor and still does the same thing, i have tried every USB port on the motherboard, removed cmos battery for the day different keyboard, i tried only 1 ram stick and only the OS HDD, different power supply.
Nothing is working for me so now i need help please.
I will try to answer any questions to the best of my knowledge.

PC specs:
Intel Pentium E2160
ASUS P5GC-MX/1333
4Gb DDR2 400 ram
AMD Radeon R5 240
Win 7 Ultimate 32 bit

USB keyboard + PS2 to USB adaptor

1415826 2016-02-10 12:06:00 Does the keyboard function properly outside of the BIOS?

It seems you have tried all the steps to try and fault it.

I would probably flash the BIOS, as it may have stuffed up in keyboard handling.

Cheers,

1415827 2016-02-10 15:41:00 Yea keyboard works fine with windows, ill try flash today snd get back dattyd1 (17448)
1415828 2016-02-10 19:43:00 Have you tried another Keyboard ?

Some Keyboards simply dont like the BIOS settings to work, yet work fine in windows because the drivers are in the OS.

Also, just having a PS2 to USB adapter doesn't work either.
I got at least two older workshop PC's , and had it happen many times at customers places, that you need a actual PS2 keyboard (no adapter) because the USB wont work. Plugging in a Actual PS2 keyboard works fine. That's why I carry one about with me while on jobs.

If the motherboard didn't have a PS2 port, then some boards the only ports that do work in the BIOS with USB are the two that are at the top (where a PS2 would be)

1415829 2016-02-10 19:57:00 Try Wainuitech's suggestions above before getting to the more involved solutions above. In my limited experience he is on the button, certainly my system will not work with a USB keyboard before it boots into Windows. CliveM (6007)
1415830 2016-02-10 21:47:00 In some BIOS settings if you use a PS2 keyboard to start with and use it to turn on legacy USB/ Keyboard options that will sometimes fix the issue with USB keyboards. Most modern motherboards though just work.

You could try resetting the CMOS with the motherboard link in case something has been inadvertantly changed, also unplug any other devices in case they are causing issues. My keyboard and mouse are plugged into a USB 3.0 port via an external hub and surprisingly that works in the BIOS just fine and I really didn't expect it to.

1415831 2016-02-10 22:00:00 PS2 to USB adaptor : often more trouble than they are worth . Adapter usually has to match the kb, ie may only work with kb it came with.

The is sometimes a setting in the bios for USB keyboard/mice

1415832 2016-02-13 06:53:00 So I tried resetting cmos by taking the battery out, no change. I flashed the bios to the latest version successfully, no change, got hold of a actual PS2 keyboard, no change. Also removed the bios chip and tried another from an identical pc and still nothing. Myself and Google are out of ideas to try. When it was working originally the pc had xp installed on it only since upgraded to win 7 ultimate has it had this problem I really need to get into bios to overclock cpu as I can't find any software with support for this chips please help dattyd1 (17448)
1415833 2016-02-13 08:56:00 The Operating system wont have anything to do with it. You should be able enter the the BIOS by tapping the Del Key on start, with or without a HDD attached OR any OS installed or not.
May sound dumb, but you do have the keyboard in the right PS2 dont you, the purple one.

Just WHAT do you mean by the line :eek:
Also removed the bios chip and tried another from an identical pc and still nothing BIOS chips are soldered in to motherboards,they require some sort of de-soldering equipment, then need to be re-soldered back in - they are NOT meant to be removed unless you know exactly what you are doing, and even then usually only for repair if they have failed.

I highly doubt it was a BIOS chip you removed, the picture below indicates a BIOS chip:

If you have been de-soldering BIOS chips, you more then likely have stuffed the board.

1415834 2016-02-13 09:12:00 Try the old INSERT key on bootup which use to clear the bios back to defaults? not sure if still does the same thing these days? apsattv (7406)
