My first guess would be a dislodged or defective lithium cell. This is a small battery that keeps the BIOS settings live and the clock running. On this board it is between two of the 16 bit PCI slots. You may need to remove some &quot;reimagined Thermal Armor&quot; (sic) &nbsp;to get to it.

The CR2032 battery was replaced. &nbsp;This didn't help.

<div>
Then 2 possibilities:<br />
1 Take everything out and start step by step...preferably &nbsp;if you can get additional parts - for testing - like Psu,Ram better... just start with the minimum &nbsp;mb,1 ram,psu,cpu and start adding.<br />
2 unfortunately you have a defective mb

The issue was a corrupted BIOS.

<div class="content wysiwyg-content">
I got an error saying that my bios settings had changed on my motherboard and that i would have to run setup. &nbsp;I reset to default settings and I cannot get the box to POST without clearing the CMOS each time. &nbsp;I cannot also get the machine to recognize the onboard m.2 card. &nbsp;I went into the onboard devices under Advanced settings and set the pci_express settings to m.2, but it didn't help.<br />
<br />
Any ideas would be appreciated.
