A single beep from the motherboard.. and then slowdown

HI,
Not sure what OS you are using (assuming some MS OS).

Is the beeping only happening while you are playing a game? This is to say that while you are sending keyboard commands to mame?
Or if you leave your computer on running a game will it eventually start beeping?
Try leaving it on on one of the more CPU intensive games to make sure that your CPU is overheating.

Could it be maybe a button is sticking and sending the same command over and over?

Also you may want to check your bios and see what the typematic rate is set to.... Bios can be configured to repeat the keys if the key is held long enough....

It does look like a keyboard buffer overflow. Have you tried chaning the buffer size?

ok all of the accessiblity options were already off so thats not the problem.


Also i applied thermal grease and while it did lower the temp by about ten degrees i am still getting the beep from the motherboard.

I tried doing what you said loki but i cannot find the "kbdclass" folder with in the registry. I followed everything up until the service folder and the "kbdclass" folder is not there. There is a "class" folder though. I dont know what the deal is.


Also i am running windows millenium (crap i know).

SirPeale:
Try running DOS MAME and see if it does it there.

lokki:
That Link I sent was for NT and newer....

I'll look around see if there is anything for ME...

MAME ignores the type-matic rate, though.  For example, start Tiger-Heli and hold down the Fire button.  The heli will fire about 1-2 times per second, at a constant rate, regardless of the typematic rate setting.

I had no idea you could change the buffer size.  That may well help.
