Possible dead moboFollow

So I've been having issues with my aging computer and since funds are limited, I'm using the band-aid approach.

I started getting BSDs a few months ago. I knew that I had some ram getting bad, but I was able to coax the PC into continuing to work. Then I was getting cmos checksum bad messages on boot up. I removed the battery and reseated it and that seemed to fix it. But it was still running a little slow and leggy.

This morning the display was a little jittery so I decided to reboot it. And it wouldn't boot. It would come on, but it wouldn't cycle to the HD. I could hear the fans and the DVD, but that's it. It just kept cycling through the DVD check, and nothing was coming up on the screen.

I figured that the old psu just wasn't giving it enough power, so I got a new one along with a stick of ram. Replaced the psu and ram and it still won't boot. A couple of times I got it to boot up, but it looked like it was in safe mode and system recovery isn't working. I have checked the connections, moved connections when I could, taken out and moved around the ram, taken out the vid card, the battery, moved the jump pin for the battery and reset the BIOS a million times. I have my boot sequence set to start with the DVD and I can't even get it to boot from my windows disk. HELP! It's Win 7, if that matters.

ETA I got a new HD about 2 months ago. It's been acting fine, but I realize at this point it could be anything.

After taking apart the entire computer and testing each piece, seems like it was that new stick of memory. Got all the old sticks in here and it's running ok. Slow, but running. Going to return that memory.

you might need a bios update to the motherboard itself to be compatible with the newer ram. What make and model motherboard do you have currently? (you can find that from CPU-Z if you don't know it off the top of your head http://www.cpuid.com/downloads/cpu-z/1.67-setup-en.exe ) Also knowing what kind of ram you have and what you tried to install would also be useful. you don't want to mix ram latencies and voltages if you can help it, even if socket type is compatible. Some voltage mix combinations can't be made to work, usually depending on slot pairing, etc. Also, what wattage was the old PSU and what is the new one rated for? Do you have a motherboard that accepts an 8 pin core voltage lead, and if so, do you have a 4 or 8 pin lead attached to it?

It's a MSI 770-C45 (I kept the box, haha). My machine is older, so I'm just trying to keep it running until I can put together a new one. And yeah, we figured that was the issue with the ram, just not compatible with the mobo. The old psu was 600 watts and so is the new one. And this mobo takes a 4 pin lead.
