Are these motherboards dead?

Specs: N/A
I have two old desktops that I stopped using because there were problems. I took them out today wanted to find out what were wrong (out of curiosity).

The problem with both desktops is that I hear the power up sound and the fans are running, but nothing shows up in the screen.

I have done the following:

1. I relocated the RAM in a different memory slot (it didn't help)
2. I removed the RAM and then powered on the PC. I do not hear continuous beep sounds. Does that mean that the motherboard is dead/broken?

Please help. Thank you :)

As long as your sure that the monitor is good, boot them again, hit F8 & try VGA mode.

You have to be sure it's not a video problem.

Unplug the power cord, open the case, then temporarily disconnect all the "non-essentials". Disconnect the external "non-essentials" as well. In other words, all you need externally is the monitor & keyboard. Internally, disconnect ALL drives (floppy, CD/DVD, hard drive), remove all RAM except for a single stick, & remove all cards except for video. While you have the case open, clear out any dirt/dust that's accumulated, then reset the BIOS using the clear_CMOS jumper.

Once you've done all that, plug in the power cord, power up the system & see what happens. If you get a display, use the keyboard to enter the BIOS & correct all the BIOS settings.

Ooh. Thank you for the suggestions. I was reading a thread and the thread mentions if no response from the motherboard during the second step, then it means it is dead. I am glad I have posted it here to further explore the problem.

I am trying out both suggestions. Thank you very much for the help :)!

Getting the "No Signal Detected" message from the monitor.

Ah and both desktops are pretty dusty (>_>) (from oily & hot environments)

Thanks again.

How can he press f8 if all he can see is blank screen.

To hear beeps motherboard speaker must be present. A bad power supply can cause similar problem.

Ah silly me. No speakers were plugged in. I assumed from the thread I read that it was sound made ... well.. somehow.

One of the motherboards has an LED light that goes green when powered on (but still nothing shows up in the display and such). The fan does not run (anymore?) with this motherboard.

The other motherboard doesn't have an LED light. The fan runs.

For both motherboards, nothing shows up in the screen.

Thank you very much to all :) I really appreciate your kindness!
