The arrow keys on my keyboard (as well as the Pause br., Insert, and Delete keys) are performing the wrong functions. I have checked my language settings, reinstalled the keyboard drivers, restarted the computer multiple times, and run a Malwarebytes scan. The keys in question, and the functions they are performing, are as follows:
Pause Br. - Insert
Insert - Delete
Delete - Home (which is weird, seeing as I don't even have a designated "home" key)
Pg up - Page down
Pg dn - Left arrow
Up arrow - Down arrow
Left arrow - Up arrow
Down arrow - Right arrow
Right arrow - 7 (note that the actual 7 key is functioning perfectly normal)
All other keys are working as normal, per my own observation and a keyboard tester site. The issue began when I opened my computer from sleep, after carrying it around all day for classes. The keys were working normally this morning as I was using them to play a game, and I cannot think of anything that would have changed in the software or hardware since then unless heat could have been a factor. What could be the problem? And how can I fix it?
