Computer freezes green screen

Hi, I am hoping somebody could provide some insight.

My computer recently started freezing and I get a solid green screen (no text). There's no new hardware. It happens randomly but I notice mostly when I'm watching videos on browser or video player. I don't recall this happening when gaming (dota2, etc).

When it freezes, nothing responds other than a hard reset. Ctrl+shift+windows+B doesn't do anything. After it hard reset it is usually fine for awhile.

Windows Error Log:

Description. A problem with your hardware caused Windows to stop working correctly. Problem signature. Problem Event Name: LiveKernelEvent. Code: 1a8

What component do you think is causing this?

I have suspected it could be RAM, but ran a short ram test no problem. Or it could be my 4 year old r9 380 which I used a couple of months for crypto mining... or it could be my junk 9 year old Enlight PSU :P

First thing I could try is uninstall the graphics card driver and installed the latest version. If that doesn't fix it then try downloading a stress test for the graphics card such as Furmark

It might be faulty GPU connection or HMDI/DVI/DP cable. I had some weird screen textures all over my monitor - I though my GPU is a goner but then I played with the cable a bit - unplugged and plugged it to monitor and GPU and it's fine for few weeks now.

@duntastar88: Thank you for your reply. There was a radeon graphics update, so I did a Factory Reset install on the driver.

@gerygo: Thanks, will try this if it still freezes after the driver update

UPDATE: my computer has spontaneously combusted, destroying everything within a 1 meter radius. Fortunately, I was soaking in a nice long bath, and therefore I escaped without any fatal injuries.

But yeah, I think I did one too many ill-timed hard resets. Seems like the OS got corrupted and won't boot anymore. Too lazy to reinstall the OS, so I'm thinking its time to buy a new PC. Farewell 2500K, you have served so well since Jan 2012.
