system has recovered from a serious error? dump files help?!!?

everytime i start my pc it comes up with this error report and the error report says it is a device driver or video driver? tried to download a patch for it but my service pack is newer than the patch so it wont do it! found something that says it is something to do with dump files but have no idea what these are or if it is right that they are the problem. at one point pc would just get to screensaver and restart itself over and over until i figured f8 would start in a previous suitable configuration help!!!
