System E-machine C1844 AMD AthlonXP System had Power supply, motherboard bundle with Biostar M7VIG400 changed. System was booted with non-emachine keyboard and mouse and worked fine. Afterwards my sister got the pc back and used the original keyboard and mouse and system boots but mouse and keyboard don't work and apparetly machine stops at log on. I don't think so, but are keyboard and mouse for e-machine propietary? If not then would doing an F8 along with a repair the way to go? Thanks.
