I was trying to unlock the 4th core on my amd x3 455 using an msi 870-g45 motherboard. After initial attempts proved to be unstable I tried marginally increasing power to the cpu as several people on this forum suggested. I increased it initially to 1.35 volts and it seemed a bit more stable so i tried 1.43ish.

The computer no longer posts.
ive tried reseting the cmos both with jumpers and by pulling the battery.


The question is, is there a way to fix this.

and if not, should i be looking to replace my motherboard my cpu or both. and is there a good way to test to see where the problem is before i spend more.
