I'n not getting an output signal to my monitor. When I boot up, should I be hearing the BIOS beeping sound from this motherboard? I am not getting it.

Thanks.

From the sound of it, or rather the non-sound, the problem is most likely with your computer. The simplest way to test this is to connect a different, known good, monitor to your computer and see if there is any signal. Alternatively, you could connect your monitor to another computer to make sure that the monitor is working.

 

Once you know you have a working monitor attached to your computer it is time to worry about the computer itself. Take the side off and see if any LEDs come on and fans turn when you power up. If none of this happens then first check that your mains electricity is getting to the PSU - check any fuses in line and the voltage at the computer end of the cable if you have a multi-meter. If you don't have a multi-meter basic ones which are sufficiently accurate are quite cheap to buy, I can readily buy one in the UK for less than £10. Your mains supply voltage will probably be 110V AC since you appear to live in the Americas.

 

If the mains are getting to the PSU, are there any voltages apparent in the computer itself ?  Again, use the multi-meter and look for 12 and 5V lines. If you do not appear to be getting any voltage anywhere probably your PSU has died but that is enough for one session.

 

Post back.

Every item of modern electronics has a "standby" voltage that is on 24/7/365.  If it gets confused or excited, the device (TV, PC, printer, etc.) won't turn on.  Unplug it from the wall, wait two minutes, plug it back in, and try it.  This fixes at least two TV's, PC's, or printers for me every month!

 

Yes, you should be able to hear the fans spin and the hard disk drive spin up when you turn it on.

Biostar says that system board has an HDMI output connector.  Why not get an HDMI cable?

great question. ;) hadn't seen it. thanks.

 

anyway, no output signal via HDMI either.

 

even if my SSD is bad, i should still get that BIOS screen.

If my memory was bad, would I still get the BIOS screen?

Not necessarily. Try taking each stick out one at a time. Also try clearing the CMOS. Here is good tutorial for doing so.

You really ought to buy, beg, or borrow a VGA monitor  and see what it does.

And yes, you should still see the BIOS screen.  The memory testing; though, is worth trying. Your video is using some of it as "shared memory" and, if it has failed, poof, no video.

why? I have the HDMI output and also the VGA converter to HDMI, both fail. In the past, the VGA converter worked. The odds I have 2 issues seem remote, no?

Are you saying if I have 2 memory sticks, if 1 is bad, removing it may allow the other to work?

1) We do not know if the problem is with your TV or the PC which is why I suggested trying a , known good, VGA monitor.  I have seen several TV/monitors where one of the ports went bad.

2)  You are using the system memory for the display so, if one of the modules fails you will get no video.  The actual video chip is also part of the CPU; but, lets hope it's not that (It could be; but, that is much rarer)

the tv is good. I have a second computer and used the same cable and HDMI port on the TV. So that end works fine.

That board requires an external speaker. Do you have a speaker connected to the F-Panel pins on the board?

Remove all the memory, boot it up and see if it'll beep a no memory error code.
