My own computer is a Mac. I think with a Mac, the display comes up
before it checks the memory. On a PC, would bad memory keep the monitor
light from turning green?


It can, it really depends on the fault though. If the RAM is bad in a
location that prevents the POST from running then the display adapter will
never be initialized. Seems I've had Macs with bad enough RAM that they
wouldn't show anything on the screen either but I haven't had a ton of
exposure to the recent ones.

Well, a man more familiar with PCs got the display going by removing the
CPU and plugging it back in. I suppose in each case where I'd found an
open ground on the computer or monitor, its counterpart supplied the
necessary ground. He found it still needs a new motherboard.
