Evenings chaps 
Had a nice fun start to my evening here, last night my pc froze mid game and I just hard it shut down and went to bed assumed it was just a generic problem that sometimes happens.
However today it won't give me an input signal on my monitor at all, checked all the connections and tried a different monitor and cables all the same.
At first I thought it was the GPU but that seems to be fine, all the lights come on no problem.
However my motherboard (Asus hero vi x370) is reading a post error of 02 which relates to an issue with the CPUs microcode. Unfortunately I don't have any spare components I can swap in and out. Do you guys think I should buy a cheap compatible CPU and swap it out or is it likely to be another issue?
