Dell Vostro 420 computer i got from work has a cmos checksum error?
And some other stuff and then
"Cmos checksum error" Strike the f1 key to continue or f2 to run the setup utility. I pressed F2 and a clicking noise (Sort of a clickish beeping or something) anyway, it was not a fan problem because it only ocoured when i pressed a key. I need help me and my son have been stuck on this for a while.
