R9 290: Artifacts have started to appear recently, today my computer black screened and the fan speed increased to 100%

[Freezethaw]

While I was watching YouTube I exited full screen and coloured lines started to appear and flash across one of my monitors. This had happened before and was fixed by unplugging and plugging the monitor back in, so I did that and it was fine until I, again, entered and exited full screen. This time the lines displayed on all my monitors, the computer black screened and the fan speed increased to 100%. I forced it to shutdown out of fear that leaving it in the state would cause more harm. But now that it has rebooted, everything seems normal. I can't find anything in Event Viewer that suggests a driver issue.

This has only occurred when watching YouTube, not in GTA V, not in Overwatch, nothing that I've been playing recently has displayed any issues. I ran Heaven benchmark on ultra for about 15 minutes and nothing odd happened. Temps at idle are ~45℃ and under load it hits 80℃.

I'm still inside my warranty for my GPU, but I'm not certain if it is this that is at fault. I think ASUS discontinued their R9 290 line so would they still be able to replace it? I can't find a way to replicate the problem either, it is entirely random. The only thing related to this is that sometimes my mouse cursor would display as a square filled with lines on the logon screen, but this has stopped recently.

Specs:
CPU: FX 8320
MOBO: ASUS M5A97 R2.0
GPU: ASUS R9 290 OC Edition
PSU: Corsair CS550M 550W
OS: Windows 10 Home (Upgraded from 7)

Check for heat issues, monitor temps in the system. Maybe a power supply issue, motherboard issue, RAM or video card from what is happening. Test the system on one RAM stick for a while, till you are sure you would have seen the issue if it would have happened.

If it happens again, try a new Windows setup with clean drivers on a spare hard drive, test things that way.

If it happens again, try a different card or power supply, or contact the vendor for warranty support.

If its the R9 (I have the MSI version), have you updated to the latest drivers from AMD ?

It sounds like your computer needs a good cleaning. Check your cooling fans, and gpu fans for dust. Also check the cpu cooling fan. Do you have cupid? I use this handy tool to monitor all temps and general running condition of my computer. I would give it a good cleaning and monitor my components with cupid to see if there is an issue somewhere.
