Some of the keys on my laptop keyboard aren't working

[Jac-Jen]

Im not sure that this is where it belongs but here i go. About two months ago my computer suddenly presented me with an issue ive been fighting with. Certain keys on my keyboard arent working. All the ones that arent working as far as i know are both of my six's, five above the keyboard, function lock key, underscore, backslash, tilda, and the addition key on the numpad.

Ive looked at many "fixes" such as, Mouse buttons in ease of access, reinstalling my keyboard driver, and i even reinstalled windows most recently, none of which have had any effect. The more i see the more i think it may be a registry issue, but im too afraid to mess with anything in there for fear of permanent damage. Any help is greatly appreciated.

Thanks, but ive already done all i can with that troubleshooting. I'll run the key test one more time and see if anything new pops up. I've browsed the internet for about a week now and havent found anything that has helped yet. Im not sure what files i would need to post to help the most either. Here is the Failure id for the keyboard test, if it helps. 0K2EKA-8Q99H3-XD7URG-G1JM13
