I am working on few machines which are quite old, manufactured in 2000(PIII, MX6BEZ board, 128MB RAM) and need to get them working for a special project. A colligue of mine had all the hard drives(Fujitsu, 10.2GGB, model no MPF3102AT, No OS) and memomry removed from those machines 1 or 2 years back( not sure). Now when I am trying to install those hard drives and memory back to those machines , I am not being able to have the hard drive recognized by the motherboard. It keeps telling me no primary drive. I tried to test them with a good working machine and same thing happend. I also experience too much heat from the memory stick when I put them into slot. In some machines I could smell something burning or frying. I tried to format a drive ( fortunately that was recognized) and took 3 hours to complete 9% of it. Could you please suggest me what cause this kind of issue with hard drive and meomory so that I can stream down the issue ? As we are planning to use these machines for about six months time, I need to make sure they will be dependable enough to go for them.Please advise.
