Heart of a Parts Box System

A few years ago, my computer was running sluggishly. I started swapping parts, memory, hard drive, upped the CPU, etc. Since none of those fixed the issues I was having, I held on to the old parts. Then my daughter's computer was stolen, and pretty much all that I needed was a motherboard and case. And an OS, which unfortunately meant Win 11, which also meant a new CPU because the one that I had previously pulled for upgrade was no longer up to drill. And more memory. So even though I had already purchased this motherboard, it was cheaper to get her a laptop that was on a one day deal than finish this one. So it sat in a box with the other parts. Fast forward a bit and Microsoft is ending support for Windows 10, not even selling a new license, and my family machine has reached the end of the road. With my grand kids liking little online games and videos, I didn't want to have the computer that I use for my banking and bill payments used for that without a fully supported OS. Some of those games come from Россия for goodness sake! So a new processor, hard drive and more memory later, it fired up and loaded Windows 11 first try. Even though the memory was not on the QVL. THAT, by the way, is the only "con" that I can think of for this board. Most of them are a little hard to navigate, but this one seems completely random and I gave up on finding approved sticks after about an hour. I had two 8's on hand and got two more of the same ones, but for some reason, the old ones go by the brand name, the new ones by the parent company. A Dodge/Chrysler type of thing. (All tech metaphors have to involve food or transportation.) ASUS has a reputation for being tolerant of memory, so I was pretty confident that they would work. I haven't finished everything yet... I have multiple TB of data to copy to external drives first. But initial tests show a machine that works well, even though the parts were spread out over several years. Couple of minor details. My SSD is the M.2 style with an aftermarket heatsink. The TPM module fits with about 2 pieces of card-stock clearance. There are no fan headers near the front; I haven't seen any µ-ATX boards that do, but I haven't looked at all of them. The BIOS was sufficiently up to date for the CPU that I used, even after sitting for years. At my age, this will probably be my last build. Glad I got a good board as the centerpiece.

Some Problems

Extremely hard to set up for multi boot systems and hard to find info on BIOS settings. I still have one problem, the when I get updates in Windows and hit restart the system shuts down and tries to restart but gives a black window stating it insert bootable media and hit any key. I have to power off for about a minute and power on and system restarts.

Dear Valued Customer, We are really sorry to hear about the restart issue you are experiencing with your new ASUS motherboard, this is definitely not the norm and is not the kind of experience we want our customers to have with any of our products. Please follow the steps in the following FAQ to troubleshoot the issue: https://www.asus.com/support/faq/1030210/ Ensure you have the latest BIOS version installed as well. If you have the latest version installed and you're using the default settings but you're still getting the restart issue where it asks to insert bootable media then you might have a defective motherboard. If you think it is defective then we would recommend an RMA (Return Merchandise Authorization) to get your unit serviced under warranty if you are outside of the return window. We do stand behind our product and we continuously strive to improve our products and processes in order to achieve customer service excellence. For more information send us an email at customerloyalty@asus.com and provide the case number "N2410004186-0003" for reference. We’ll do our best to provide a quick resolution to your case.

Nice mother CMOS battery reset option for booting

it is a very nice motherboard but...the cmos battery was kind of a trouble for me but not really sure because it did solved me a problem removing it and putting it back in because whenever i saved and exit my bios settings it only saved and exit completely no booting up to windows but instead a black display or no display maybe because the boot order? but atleast make it automatic if it doesn't detect...only if i havent heard of this setting but for me it should always be turned on...it kinda gave me anxiety as a first time builder 😅
