no monitor

[Kathy]

I am trying to help my daughter fix her computer. It will boot up, but
there will be one long high pitched beep then two short ones, a few
seconds later there will be 2 low pitched beeps. There is nothing on
monitor.

Could it just be the video card?

Thanks
Kathy

One long 2 short usually means a video error
You need to check your connection cables first.Then if they are fine you need to
shut the system down and open the case to make sure the Video card is properly
seated in its slot.

I have done all that. I found out it is not the video card, it works in
another computer.

Any ideas?

up your BIOS maker and then interpret the beep codes.

Those beeps are known a beep codes and they're telling you something.
Unfortunately, there's no standardization (although there are some codes
that tend to be the same). Your best bet is to visit the motherboard
manufacturer's web site and see what those two particular codes mean.

OK, it is supposed to be the video card. When I put the video card in
another computer there were no problems. I tried disconnecting
everything and it would boot and I had a screen on monitor that said
there were no drives attached. As soon as I connect any cable to the
hard drive, cd or floppy it beeps. Same thing with the power connections.

It was the power supply.
