Dear sirs or madams: I have a Midwest micro computer about 9 yrs. Old. We use it for the games that are part of the windows version loaded into it permanently. A few days ago it would not load and come on as it did before. The messages say the hard drive is not installed and the battery is low. Will this low battery cause this problem or it something else. It also says CMOS isn't right. Thank you. Jim Passer. [email protected]
