Error: no boot disk has been detected or the disk has failed.

[Jarclark]

All of a sudden my monitor wasn't getting a signal from my computer so I ordered a new video card and that did nothing. So next I ordered a new motherboard and not the monitor gets a signal but it gives me that error code and the fan goes on hyper mode. It won't let me get to the boot process and no matter which sata I plug the hard drive into it still says the same thing. I tried plugging the old video card into the new motherboard and it gave me 6 beeps with a blinking orange light. And would not give a signal to the monitor. Not sure where to go from here the old motherboard was m3970am angelica the new motherboard is m3970cm. Any assistance would be greatly appreciated.

Not sure why you are messing around with motherboards and graphic cards when no boot disk usually means hard drive failed.

Can you physically remove the disk-drive, and connect it as a "secondary" disk-drive in some other desktop computer?

Hint: during this trouble-shooting, you might disconnect the "power" and "data" cables from the back of the CD/DVD device on the other computer, and connect your disk-drive to those cables.

Then, boot that computer.  Has Windows recognized the disk-drive?

If so, can any files/folders on the disk-drive be accessed?

If not, the disk-drive now is a "door-stop-brick", and must be replaced.

To ieee48: I'm not trying to be rude but if you would have read my whole statement you would have noticed that I said my initial problem was the monitor wasn't getting a signal from my computer. That's when I replaced the video card and it still didn't work so I replaced the motherboard. And now after doing both of those I'm getting a signal to the monitor again but it is coming up with a message that says no boot disk has been detected or the boot disk has failed.

All of which would be explained by a failing hard drive as in that Windows stops running and cannot provide anything for the video card to display!

To mdklassen: I tried your suggestion and plugged my hard drive into another computer and the hard drive functions.

A hard drive that fails to boot will often be recognized in another PC.

That's why you can often connect a hard drive that won't boot to a working PC and retrieve files from it.

It just won't boot, it cannot be used as a boot device hence no boot disk.

Went returned the new motherboard I bought for another one and now everything works. I knew it had to be something along those lines because the old motherboard and video card wouldn't even put a signal to the monitor but the new motherboard and video card would send a signal to the monitor just with a brand new error of no boot disk. I was stumped at first but the more I retraced the original symptoms the more positive I became. Thanks for your guys help.

The cause could have been BIOS settings on any of the 3 motherboards.

If your disk-drive was not listed as being "eligible" to be a "bootable" device,

then you would get the "no boot device" message, after failing to boot from the "eligible" devices.

If you have a shoe-box that is full of sandals, high-heels, and flip-flops, and you try to find boots in the shoe-box, you will get no boot device. 

Or, if the BIOS interface to the disk-drive was set as 'IDE' instead of 'AHCI', and Windows was installed when the disk-drive was interfaced as an 'AHCI' device, the boot will fail.

You cannot plug-in your USA-made shaver/hair-dryer into wall-plugs in Great Britain, nor anywhere in Europe.

The physical shape of those plugs are specific to the USA/Canada, not for many foreign countries.
