|Champ - why not advise desktop/laptop/make/model in your original post? My crystal ball is on holiday this week.|
I would remove and reinstall the k/b to see if disturbng cures the problem.
If not, as Chris advises, time to try a new k/b.
Here in the UK, generaly a new laptop one can be found for around £15-20.
Googling can probably find a video on how to fit.
Please advise back on progress.
Good Luck - Keep us posted.
