HP ProLiant ML110 G6, BIOS resetting itself after boot up

[bacKz]

Hey "Linus Community". So I've got an "ultra gaming budget pc" 9 months ago, not a new one but we can say a refurbished one that works just fine and his model is: Hp ProLiant ML110 G6 Server (it's a server basically, but it is working fine for gaming and other stuff, as you get what you pay). So for 7-8 months the server was booting fine and without having any BIOS reset problem every time I plug in the cables of the PC , I hear a "click sound" the fans start to spin on max speed for 1 second then it makes a "click sound" again and after 5 seconds it does again that "clicking sound" and the fans start to spin at full speed again for 15 seconds after that it finally POST-s and the famous "HP Splash Screen" appears while resetting every single setting in the BIOS to it's default state. This happens every single time I plug in the pc cables in socket. I tried to replace the CMOS battery with a new one but it's still the same. Hope I provided enought details of the issue. Any suggestions would be appreciated. Thanks.
