So my computer normally works great. 2 days ago it did not power up which was weird. So I checked the temps and my cpu was getting really hot like going up by 1 every second up to about 100+ before just powering off itself. I have tried adding a new cooler with new thermal paste and that didn’t work. I took apart everything and put it back together, still no hope. I have now checked the back of my motherboard and noticed small signs of VRM burns. I think my backplate was on wrong and was touch a pin for one of the VRMs for years and is now showing damage. The thing that gets me is the pc powers up and turns on so I think it can be fixed but the VRM damage makes me think a new motherboard is my best option here. Do you guys think I should just get a new motherboard since the VRM is showing a little burn damage?
