Before Christmas, there were a few scattered reports about failures and random combustion for the Asus ROG Maximum Z690 Hero motherboards. Following the jolly holiday, more and more reports have started to come out from board owners who have had their hardware literally go up in smoke.

Following a rather quick investigation by Asus, the company has pushed out an announcement, issued a recall, and are offering replacement components to everyone that has bought that particular motherboard.

The issues have been reported through various social media posts and on the official Asus forums. One particular user, maximumrog57, provided some details about their experience that left a "penny sized burn mark" on their board. This person said initially they were unable to get through POST and noticed an error code 53. This code related to an issue with RAM. However, they soon noticed the burnt area of their board just below the area where the POST codes are displayed.

Other users have reported issues with their boards. These issues included hearing audible pops, the smell of burning electronics, and random system shutdowns.

The YouTube channel Actually Hardcore Overclocking looked into the claims from users who have been experiencing issues with the game. They discovered that there is a capacitor on the Z690 Hero that was improperly installed. Asus has confirmed these findings and are recalling all of the boards and offering replacements.

The full statement from Asus can be found below. If you own this motherboard, you should follow their directions as soon as possible.
