Weird CMOS Battery Issue

[KMR]

Hello, 

 

I recently got myself a new gaming computer but there is this weird CMOS Issue. 
My rig: 

- Gigabyte B450m DS3H (Running BIOS ver F41)

- Ryzen 5 3600 (Running at stock, I just have ryzen master installed)

- Asus TUF 1660 Gaming OC

- G.Skill Ripjaws V 2x8 (Running XMP at 2933Mhz, Stable)

- Windows 10 Pro (ver 1903)

- 1TB Seagate Barracuda + 480GB Kingston A400

 

The computer works completely fine and everything is stable, I'm getting the performance I'm supposed to get from such a system comparing it to benchmarks. The weird Issue is that whenever I turn on the PC after a long time; like when I go to sleep;  all the fans spin but nothing posts, there's no output. I have to take out my GPU, take out the CMOS Battery and then put it back in after a minute for the computer to post again. Once the PC is back on, everything works fine and I just have to turn XMP back on.

 

I tried using another CMOS Battery (I'm not sure if this ones good either) but the same issue persists. Any help regarding this would be appreciated. I got this gaming PC after years of waiting and it's just really sad to see such an issue with a new motherboard.

 

Thank you.
