I'm a bit stumped by this one. My computer won't display anything at all when I turn it on. There seems to be no defects to the mo_bo, or anything connected to it. The hard drive powers up, all the fans spin, and the processor warms up as well. I don't think there is anything wrong with the ram as I've given it a visual inspection and there seems to be nothing defective about it, I've smelled it to make sure it hasn't burned out, and it hasn't. I really don't know what could possibly be the cause.
