I am using Gigabyte B450 Aorus Pro Wifi motherbard, AMD Ryzen 7 2600x, Corsair DDR4 2x8GB 3200Mhz RAM (CMK16GX4M2B3200C16). My OS is Windows 10 64-bit.
I have this weird problem with my desktop PC. Sometimes, PC fails to boot up because I cannot see the bios boot-up screen. To fix this problem, I have to pull out the power plug, wait for a pop sound, then put back the power plug. Now, I can see the bios boot-up screen on boot-up. The problem is this action of pulling out and plugging back the power plug sometimes causes the BIOS settings to be reset to default. This happens sometimes only when I was using bios firmware version F2. Yesterday, I upgraded bios firmware to F5. Now, the action of pulling out and plugging back the power plug ALWAYS causes the BIOS settings to be reset to default.
This is a problem because I need to change BIOS settings to use 3200Mhz RAM clock and run Ubuntu virtual machines on Virtualbox.
I bought the motherboard a few weeks ago. It is unlikely the battery can run out so soon.
