So, I have been doing youtube for about three months now, and everything has been going smoothly, I was using MSI Afterburner to record, and one day I went to record a video, and I started to lag until my computer crashed for some reason, I've tried just about everything, but nothing will work, so, what I need is help finding a new one, preferably free, I would like a full version too. If it is paid, I would prefer $15 or under for the license.

(Programs I've tried so far that don't work for me: OBS, MSI Afterburner, Hypercam 2)
Just if you were wondering, I'm running Windows 8.1 on an HP Pavilion Laptop.
