Keyboard loses ability to repeat characters?

[Graeme]

Hi all

I'm having problems with a Win 2000 PC - on boot everything is fine but,
after a short period, the keyboard refuses to accept the same keypress twice
in a row -so, instead of "cabbage" you'd get "cabage". At the same time
there's a quiet 'beep' as though the keyboard buffer was full - however it
will happily accept anyother character without the beep.

There seems to be no particular piece of software that it happens with. If
you reboot or uninstall/reinstall the keyboard it's fine for a while but
then starts it's behaviour again.

We've changed keyboards, changed drivers, reloaded the dos keyboard drivers,
changed all keyboard settings in the control panel and changed the registry
entry to enlarge the keyboard buffer to no avail. I've searched the web and
newsgroups but I cannot find a solution - any pointers?

Thanks

GT

You are unintentionally enabling Filter keys perhaps?

Hi Bob

We've tried that too!

Is the "soft beep" coming from the "external speakers"(likely software
produced) or "internal motherboard speaker" (likely BIOS produced)?

Hi Bob

It's the system (internal) speaker - sounds very similar to the sort of beep
you would expect if the keyboard buffer were full and a key was being held
down - it sounds each time you press the same key twice but does not when
you press any other key..

Motherboard or Keyboard problem would be my assessment. Try swapping
keyboard first.

Hi (again)

We've already tried the keyboard swap - I'll see if maybe using a USB one
instead of a ps2 works - if not then I guess it's time to either try
flashing the bios or a new motherboard.

Thank you

Thanks for all the input - a USB keyboard has cured the problem but we are
none the wiser as to why it started in the first place - some hardware
problem with the ps2 port most likely

Thanks again
