Question PC issues, turns on but does not display, beeps 5 times.

[SatsumaSegment]

I've been having an issue with my PC for a little while now. Every now and then I'll turn it on and the debug speaker will beep five times and it won't display anything.

I've read that 5 beeps are a processor issue, however, I've managed to log in without the display just fine, I know this because I have a Razer Chroma keyboard and my custom light settings will come on once I'm logged in. This means surely it can't be an issue with the processor?

I know for a fact that it is not an issue with the monitor or display cable so I'm thinking the GPU but it works eventually if I keep turning my PC on and off, some times sooner than others. It seems to have gotten worse lately though. Is there any way to fix this?
Please help! Thank you =)

Ram: 16GB Chorsair Vengeance DDR4
