Comp crashing after hitting stop recording using FRAPS

Hi, recently ive been trying to get my FPS fixed and all of a sudden without touching anything my vids are crashing my computer once I click that hotkey to stop recording. I freeze for a good 15 seconds and than if I click or move anything my comp crash's, I figured out the reason why. My videos are being saved at 4 gigs, im recording at 25 fps / half size.


I'm using FRAPS(www.fraps.com) to record, I might o fhit something. I've got a reply telling me I needed more HD space =/ but 4 gigs for a 2 second clip is outrageous, and its never happened to me befor.
