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
get another copy of the diagnostic program
check to see if you have a software problem
