I thought there was a button sequence to do that but checking the manual and the forum it appears that the reset is a menu item. Which doesn't help if you cannot get to the menu.
If you are getting 'low battery' with fresh batteries you might check the battery contacts in the camera. Cameras that old often have a bit of tarnish on them which prevents full voltage. And the k-x was notoriously finicky about batteries. I suspect it was marginal for use with AA batteries and any drop in voltage caused various unexplained issues. At the time the accepted wisdom was that Eneloop rechargeable ones worked the best as they had a 'flatter' voltage loss curve under use.
Anyway try cleaning the battery contacts. A pencil eraser can work or electronic contact cleaner if the pencil doesn't help. Not sure if that will help with your main problem but if the camera is not getting full voltage its hard to say what that might cause.
