I have a problem that has just seemed to happen in that I have no keyboard function during boot up & hence I cannot get into my BIOS.

I was using a USB keyboard so I borrowed a PS2 keyboard from a friend & that also will not work during boot up.

Both keyboards function when in Windows so the USB port & PS2 port are functional.

I built this computer last week & the USB keyboard was working initially, but I have been in the BIOS that many times I thought I may have disabled USB legacy support by mistake. But this does not explain why the PS2 one will not work.

Can anyone help?

I am at a loss....

Are you sure you are pressing the right key to get into the bios? Are you sure you are pressing it soon enough? - on faster systems you may need to press it almost immediately after booting - press it repeatedly - don't hold down the key.

Make sure you have the PS/2 keyboard in the right port if there are two. On many mboards (especially those with Intel chipsets) the keyboard or mouse will work in either PS/2 port but it may not be recognized by the bios during bootup if it is not in the right port.
Some PS/2 keyboards have a button that toggles the F keys on/off - if it is toggled off and an F key is required to be pressed to get into the bios, you won't be able to get into it (usually there is an led that indicates whether it is on).
Or
- try another PS/2 keyboard - some are not 100% compatible with the standard specs.
- try clearing the cmos by moving a jumper on the mboard off/back on.

If those things don't apply, or don't help, is your computer protected from power surges/spikes with something decent? If it isn't the mboard keyboard controller or some circuit on the mboard related to it may have been damaged by one of those.

Thanks for the reply

Yes I made sure the keyboards were in the right port.

The delete key is the one for the BIOS & I start pressing it before I can see any boot screen at all, & keep pressing it.

It actually appears that I do not have any keyboard function at all because I did hit the reset button to try again & then ended up with screen "Windows did not load properly" & you have 30secs to make a load choice. At this point the keyboard will not scroll or the enter key does not function.

I have thought about clearing my CMOS (jumper on mainboard)but I am going to wait for a reply from MSI before I take that step.

The board is a MSI P965 Platinum.

"I start pressing it before I can see any boot screen at all, & keep pressing it."
Don't hold it down.

"PS> Computer protected via surge boards & UPS"
Any possibility of lightning in your area since the keyboard last worked to get into the bios? Sometimes even a system protected against surges/spikes will be damaged by lightning, even if you weren't aware of nearby strikes - lightning hitting the power grid or your internet cable can certainly do that.
Is everything connected to your computer that connects to AC protected? e.g. your printer, router, modem?
Is your internet connection cable protected - tel cable (DSL or ADSL) or coax (cable)?
If there is an led or leds that indicates the surge/spike protection is working is/are it/they still on (in the case of lightning it/they may or may not be)?

The clear cmos procedure is detailed in most mboard manuals.

Yep all vital equipment protected, & no thunderstorms or lightning recently.
All protectors showing status lights green.

My UPS does voltage regualation as well.

I did find another site via google search where someone had a very similar problem. His problem was also of a sudden onset with no valid cause. His only solution in the end was to clear the CMOS.

For info:

I ended up clearing the CMOS & then all was well. My USB keyboard was recognised straight away.

There was still no plausible expalnation as to why this happened in the first place, & MSI could not offer a reason either..

Thanks for finishing this thread.
