How To Handle Nvdia Geforce 6150se Nforce 430 1105 Mb

One night while loging off,I noticed a small memo from "cnet" specifying that by running their testtracker software, i could isolate the reaon why i got the apparent error and a poosible clue as to what to do to alleviate it. i read the info on the memo and proceeded and found that a "date" was missing or had been unabled to be updated on a file due to the rules laid down and that prevented an update on he particular file. (only found that out much later.) the date was only the beginning and the the abilities of cnet and finding where to go in the application left me totally lost. i need help in in knowing ho and what exactly to do when the date is accidentally or intentionally changed. and what occurs after that point. does the date affect anything other area.
