MSI GT70 diagnoses

[Theguywhobea]

Alright everyone, I think this issue must be motherboard related, however I figured I would ask everyone here first just in case. Just picked up another MSI GT70 from ebay. This one was listed as a no POST so I at least got it cheap. Started out by figuring it was just a RAM issue, and sure enough after removing the single stick of RAM that was in there and replacing it with a few known good sticks it booted to the BIOS screen. Got an SSD in there with windows on it and it booted into the OS. At first it seemed all fine until the screen went all fuzzy and it shut off. After that it wouldn't reboot until I left it sitting for around an our. Tried using DDU to get rid of the old drivers as I suspected they might be the cause. Still got the same issue after a reboot. I happen to have an extra 4th gen i7 laptop CPU and a spare 880m so I threw those in. At this point I have replaced the RAM, CPU and GPU, and after booting into Windows I got the same error. Seems like it must be heat related or something? I took a good look at the motherboard (at least all the parts I could see) and none of it seemed burned or anything. Anyone have any idea what to look for other than replacing the motherboard?
