I recently reformated the hard drive in a 5 year old e-machines computer. I thought I did. I used the DOS format command and it seemed to go through the whole process. I am running windows 98ME.
I used the disc that came with the computer (which includes windows) and re-installed everything clean. The only problem is, when I turn the thing back on it seems to have some old software remaining on it. I looked at the properties of the software and it says that it was installed in 2000. I know it didn't originally come on the computer.
How could a hard drive format miss anything? I thought everything would be wiped clean. I am also having error messages pop up when I access windows explorer and some other programs. For example: MSHTML.DLL keeps causing erros (all of the problems are related to .DLL files). I really would appreciate it if someone could help me out. Thank you.
