Keyboard buffer seems to overload.

I recently bought a brand new laptop running XP and, owing to lack of desk space, use it as the "heart" of a desktop system too. The laptop is therefore connected to an external monitor and keyboard for much of the time.
I am generally familiar with the keyboard control options in XP and have increased the typematic rate in the setup table, however, the keyboard buffer seems to fill very rapidly and the keyboard stops or delivers characters at a crawl.
I have looked in the event log and restored the computer to an earlier date once - this worked for a short while until the probelm reappeared again shortly afterwards.
The problem affects both the laptop keyboard and the external keyboard alike.
Has anyone got any ideas?

Hi BrianMacMoth,
The buffer size and function is set by a programmer, and usually can't be changed by a user. The buffer is in RAM and is not affected by the type of keyboard. If the working of a computer has changed, one has to suspect that the computer needs cleaning, physically and/or of the HDD, or there may be malware causing the change.

Make sure your security is up to snuf and your disks are free of excessive temporary files - atf-cleaner.exe is good.

 

Hello Sparrow,
Thanks for the reply.
The laptop is only a few weeks old, so I would be surprised if cleaning is likely to be the answer. The temporary files and security idea is worth a look, particularly as restoring the system worked the first time, possibly deleting a surreptitiously installed malware program.
Many thanks
