I have a hp m820n and it crashes or won't start and has a long beep then a short beep i am wanting to know if that is the motherboard that is crashed

this is a commom issue with windows 8 on HPs. turn off your automatic updates then contact windows. the updates usually gets to 13% and then freezes.

5 Short BeepsYour motherboard is complaining. Try reseating the memory and rebooting. If that doesn't help, you should consider another motherboard. You could probably get away with just replacing the CPU, but that's not too cost-effective. Its just time to upgrade!

No! the configuration settup is different, not to mention the lay out. The modem must replaced with the original specifications that are called for.

what device? is *********** board won't start? Or a hardware doesn't start like ram or your printer
If the problem is your motherboard check all your hardwares and connectors like this:

1. If the motherboard won't start if you click the power button check the LED(the small light bulb on your motherboard) if its glowing. If not, check the connector of your power supply or check the power supply if its working by looking its fan if revolving.
2. If you push the button and there's a sign of power but didn't start up that will appear on your screen check the connection of your monitor screen to your desktop computer. If it's connected, remove your RAM from the motherboard and insert it to another memory slot to check if it's broken.
3. Last, if you push the power button and here 1 short beep but the boot screen didn't appeared from your screen check your graphic card. Remove the graphic card and re-insert it again to its graphic card slot and plug in your monitor connector to it. If it still remain that way, buy a new graphic card.
   

Hello, would love to help. When last did you boot / shutdown successfully and what were you working on?

How many beeps? Any pattern? (e.g., short, short, long, long, low, high) ?

Contact Dell, and purchase a replacement motherboard.

4 short beeps means the system timer on the motherboard is bad. You can try reseating the power connectors on the MB and resetting the CMOS memory but it's probably the motherboard. DELL'S QUALITY HAS REALLY SLIPPED!
