[connection utility log: what does peerSignalQuality do & can it cause blackouts?]

I have been having issues with a black screen 

i checked the connection utility log and found the same data spikes before each crash. i thought it could have been due to overheating - it reaches 68 and above

one thing which i am unsure about is peerSignalQuality which always reaches 255 before crashing, no matter what the temperature is 

 

what is this peerSignalQuality and can it cause blackouts?

here is an exert from the latest crash:
