You run a super wing-ding diagnostic program on your PC, and it reports that your hard drive, microprocessor, RAM, and video card have seen better days. To resolve this problem you should:

replace each part one at a time, rerunning the diagnostic before replacing the next part.
replace everything at once and rerun the diagnostic
run an exhaustive memory check
check to see if you have a software problem
get another copy of the diagnostic program
