[[[ SOLVED! ]]] NF750-G55 CMOS Checksum Error
So I just got my NF750-G55 motherboard, Phenom II x6 1090T, and G.SKILL Ripjaws Series 8GB (2 x 4GB) memory in. I hooked up a Zumax ZU-500W power supply, a hard drive, a DVD burner, and used onboard DVI real quick just to get started. I didn't put anything in a case, just layed it out on my table to get it set up real quick. Sorry for the crappy pics. Photos taken with my cell phone.
I powered it on and it just displayed the MSI NF750-G55 logo and wouldn't progress further. I had the memory in the 2 right BLUE modules so I switched them over to the two left BLACK modules. Powered the system on and same thing. Just displayed the NF750-G55 logo screen and wouldn't boot past the logo.
So I switched PSU's to a Dell 450 watt that I know for a fact works. Same Result. Then I took everything out and just had the CPU/Fan, memory, and monitor hooked up. Same result just the logo screen. So then I had the idea to clear the CMOS with the jumpers and it finally booted past the logo screen into a checksum screen. It said CMOS checksum BAD press F1 to run setup. Press F2 to load default values and continue. If I go into settings and save them and exit, it boots back into the logo screen and will not continue.
So if I clear the cmos and go back to that screen and just hit F2 to save default settings and continue, it says checking NVRAM and will not continue past that screen. I have to clear the CMOS again otherwise it will not boot past the logo screen.
So if I clear the cmos and go back to that screen and hit F11 to enter the boot menu, it says entering boot menu and will not continue past that screen.* I have to clear the CMOS again otherwise it will not boot past the logo screen.
If I clear the CMOS and boot up with just one stick of RAM, CPU, and onboard graphics, it shows this screen.
If I do F1 and make changes and save, it boots back to logo screen and won't continue. If I hit F2 to load defaults and continue it does nothing. If I hit F11 to go to boot menu it does nothing. If I attach hard drive and DVD drive, it is the same results as before. Switching to other stick of RAM returns the same results as well.
Now I am all out of ideas. I have tried a brand new motherboard battery for the CMOS but that didn't help either. Do i need to install everything in a case and continue from there? Motherboard DOA? Thanks for all your assistance!
EDIT: SOLVED! The mother board kept getting stuck at Checking NVRAM. For whatever reason the NVRAM was corrupt from the factory so flashing the BIOS rewrote over the NVRAM and it is working just fine now!
