ms-7778 motherboard boot failure

Product Name: HP Pavillion A10
Operating System: Microsoft Windows 7 (64-bit)

The screen froze with the screensaver 3D logo in a tinyshrunken box on my trusty Pavillion A10. It was unresponsive to keyboard or mouse input (wouldn't wake up), so I powered it down with the front panel push button and powered it back up wouldn't boot. No beeps, no text, nothing on the screen. I powered it down and pulled the RAM and powered it back up and got 5 beeps. I was hoping it might be the PSU, so I pulled it and switched it out in another system and that system booted so it's not the PSU. This system has been in a clean air conditioned environment on a surge protector. When I pulled the lid, the interior was unusually clean and lint free.


Are there any other tests I can do?


Is my Mobo toast?


Thanks for any response,

As I understand you are having issues with the computer won't boot properly, don't worry as I have a few suggestions which should help you with this concern,


Going through the post as you have already mentioned that the PSU works fine on another computer this could possibly be a hardware failure with the Motherboard or the CPU. Before you could contact our HP phone support, I would suggest you follow these steps here:


To provide an accurate solution, I'll need a few more details:

What is the product number of this computer? (Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...)

What is the sequence of the blinks or beeps?


Please click on the below links once you identify the blink code and resolve the issue:

If the issue persists, I would personally suggest this could be a hardware failure. I would recommend you contact our HP phone support for available service options. If your product is out of warranty, please choose paid options to get the tech support number.
