Game/PC crash and vertical green lines?

[09ymmit07]

I was playing fishing planet when I caught a fish, and when reeling it in my pc screen went green with thick lines running over it. I left my pc for 1/2 minutes, and it turned out teamspeak and all other processes had shut down, while my pc was still on. after 1/2 minutes my pc screen went more gray-ish and more lines appeared closer to eachother. since this happened around 30 minutes ago I don't know if this is a reoccuring problem. specs coming in edit in 1 minute
edit:

I run Windows 10 Home 64 bit.

Maybe your GPU is suffering of artifacts ( let's hope not ), or it's just the SO. I've being reading some problems with w10 while gaming ( like this one, but they said it'd stop later on). Last hope for the latter option now, if it happens again post here once more.

I just cleaned my GPU, no problems since.

I have the same GPU, and pretty much the same config (A Sapphire OC edition, but still, a R9 270X). And I noticed a lot of people having the vertical lines (mines are green, purple and pink), me included.
In my case, the issue seems to come from the GPU (tested it on another monitor, same issue), plugged a console to my PC monitor, no issue.

If you're having issues of that order, as a starting point, check on another monitor or even a TV screen if the issue is still there. If it is, then it comes from the computer, probably the GPU, possibly the PSU (mine had been running fine for 2 years, and crashed for the first time a few days ago. PC crashed, hard time rebooting, then when it came back I had the lines).
If not, then it's probably the monitor.

Got mine 2+ years ago, so I accepted it. Performance wise, these cards are great for their price, but they eat a lot of power, and I don't think the cooling system allows them to live much longer than what I got, especially if you play a lot.
