Time after time I get this problem. Some times after few hours or day left plugged in it boots with Intel bios... I tried to remove battery, updating bios, setting bios to default. it fixes itself randomly.

Hello DRG,

Thanks for this information; however I would appreciate if you can provide me additional details on this issue.

When you said the board boots in American megatrends BIOS, this happens when pressing the F2 key?

• Are you able to go to the operating system?
• Can you access Intel BIOS?
• Can you provide me the AA# and Serial number of the board?
• Current BIOS version?
• Can you see the splash screen? Intel Logo?

Regards.

DRG,

This is a really unusual situation, since we do not use American Megatrends Bios in our motherboards.

The recommendations I can provide you for this issue are the following:

• Test the board out of the chassis using minimum configuration such as Motherboard, processor, 1 memory stick and power supply.
• If this behavior started after the BIOS updated, you can try rolling back to the previous BIOS version.
• If you had have this behavior since you purchase the motherboard, please send me a private message with all you personal information in order to create a service ticket and replace the product if it still under warranty.

Regards.
