Just recently I was clicking through my itunes list and then my computer started going really slow and the music stopped. When I would switch to another window some random music started playing out of my list, then I'd switch back and it would stop again. I noticed that songs were being chosen down the list really quickly and this is what slowed my computer and wouldn't let any songs play. I couldn't click on one song without it jumping to the next and so forth. I would restart my computer and then it would be fixed for a bit, but after having the computer on for an hour or so, it would happen again and I couldn't fix it without restarting. So I started pulling out plugs to pinpoint what hardware device is causing the issue, and it turns out that it's my keyboard. About a week ago my mate accidentally stepped on the end of the plug and squeezed the metal at the end of the usb drive so I couldn't fit my keyboard into a slot. I fixed it so it would fit again but it still looks bumpy in places. What could be the problem and how could I fix it? Should I just replace my keyboard? Thanks.
