Not sure if this is the right place to post this but what the heck. So I've been given a desktop for free because it's broken, I was initially going to just take the hard drive and bin it but it seems to turn on fine (no error beeps on start up). The problem is I'm not great at this sort of thing and I don't really know what's wrong with it, so here's a run down of what's going on:
The monitor gets no signal from the tower (the monitor works)
The keyboard and mouse get nothing either (no lights etc.)
I also can't turn the tower off with the power button
However the usb ports seem to work and as I said it turns on fine. I'm really tempted to just stick with the original plan and get rid, but if it's not that difficult to fix (or at least figure out what's going wrong) I'd rather do that and have a free desktop obviously. Any ideas what I can do next/what the issue might be?
