Around 5 days ago I got a blue screen while playing with the command WHEA UNCORRECTABLE ERROR(Hardware issue)
I load up the PC and will get 1 or 2 "No signal" responses to my Monitor before it eventually starts up fine.
The computer runs like normal when watching youtube,streams or browsing the internet but once i load up a game ~5mins in i get the same error code and msg
Ive had the computer for around 5 years now and I have never nor is it currently being overclocked, the temps also seem to be normal

My best guess is thats its a faulting CPU? but it seems to be hard to actually pin point what it is
Any advice or help would be greatly appreciated
