+1 for Fraps, hahah. I've used Bandican, CamStudio, Camtasia Studio, HyperCam, and yet to test out Open Broadcaster, but Fraps always keeps me going.
When that fails, I load up a trial version of Camtasia Studio since it comes with both an editing suite and recording software.
Also Fraps is one of the few software that actually can record both mic and stereo audio at the same time, which is a fault of many recording software (and my computer as well, since CS can, it just can't read these inputs/outputs on my laptop for God knows what reason).
Edit: and if you wanna make some GIFs for imgur, check out GifCam.
