my computer went from working fine to not working at all in a 24 hour time period. i have an emachines w2785 with an amd athlon 2.16 ghz processor i've upgraded it to have 1.5 gigs of memory (ddr) and about a year ago i installed an nividia geforce 5200 video card.
what it is doing now is it makes all the normal sounds (harddive reading, fans moving, etc) however nothing shows up on the moniter i have tried it on different moniters and it does the same thing i have also tried removing the new video card in hopes that it would enable the onboard one but even that did nothing. also the keyboard lights do not turn on when it's plugged in and the cooling fan on the new video card does not move. could it be a mother board issue?
either way i'm out of ideas and am in desperate need of help
