Hi,
I am repairing a MSI 785G-E53 AM3 AMD motherboard from CMOS bad checksum and thus I went off to replace my CMOS battery using a brand new sony CR2032 with the positive side facing up. They showed up the mainboard screen and the screen went blank. The power light is on and the CPU fan is running and stuff. Other than that nothing else happens. I'm not sure if that is enough information so please advice thank you
