Hardware Keyboard not working

[Zoheb318]

Randomly my hardware keyboard will stop working and my phone runs SUPER slow. Seems like something is using all the RAM but the task manager still shows 50% available. I can't track down why this is happening but this even happened after a hard reset and I didn't install any programs. What's weird is that the only remedy I found is just to wait it out. Turning the phone off doesn't help.

I know this may be a hardware problem but was wondering if anyone else was also having this issue. I have insurance so I'm not too worried but I absolutely HATE going to the sprint store or dealing with the repair center.

FWIW I'm using a custom rom and the Telus 1.04.05V radio.
