Blank screen, system on, GPU fan full blast, system unresponsive

I've been running my Ryzen / RTX build for a while now and it's been awesome. However, last night I got some weird behaviour that I want to try to understand.

Basically, while working in Windows (nothing intensive, just browsing), the screen suddenly went black and the GPU fan came on full blast. I wasn't able to turn the machine off using the front case panel and had to physically switch it off at the power supply. The machine came back up and everything now seems normal.

I wasn't running any intensive CPU or GPU applications, and I remember looking at Zotac Firestorm and seeing the GPU temp idling around 30 degrees centigrade just before the issue occurred.

Any idea what would cause this behaviour? My initial thought is GPU temp and that this felt like some sort of overheat scenario where the machine did what it could to protect the GPU. The GPU is idling at 30 and the CPU idling at 36.

Thanks for any thoughts!

Virus maybe?

Thanks for the reply. Any justification for this? Do you know of malware that would do this? Seems like odd behaviour for malware. I'll run a Bitdefender scan when I get home, just in case.

i don't know of any but it could be something else maybe a faulty card. Make sure everything is plugged in properly because that can cause issues as well.

Brand new RTX2070, but yeah, I'm wondering if it's reporting incorrect temps to the MB and it's causing the machine to enter self-preservation mode. Been absolutely fine up until now, though.

Could you get the computer running after this?

Yeah, turned it off at the plug, left it for a bit, switched it on and powered up just fine. Nothing to report, other than Chrome complaining that it hadn't shut down properly.

Could be numerous things unless it happens again it was probably just an error with the motherboard psu circuit breaker or something else. Nothing to worry about.
