I have an Acer flatscreen that works properly (I've tested it), connected to a graphics card that also works properly (also has been tested), and still it does not respond when I turn the computer on (which also works, I get green lights, and one beep).
The motherboard has onboard video as well. I've unplugged my graphics card and connected my monitor to the onboard video port. It still doesn't respond.
I've unplugged all the PCI devices and replaced them. This doesn't work. (Though, I had forgotten about the mobo battery)
I'm thinking I need a new power supply. It's the only thing I've been able to conclude in all the searches I've done so far.
Can someone help?
