I have a i5-4690K, pretty old but this problem has been occurring for years and I literally just narrowed it down to CPU. Basically when doing stuff that requires a bit of processing, like video games or video rendering, my computer will shut off. No warning, no BSOD, just suddenly it's off and restarting. It was really infrequent for a long while but has really picked up in the last year, I replaced PSU thinking that was cause and it still happened. Finally the other day after more searching I found someone with same problem and a way to check if it's CPU. GIMPS Prime95 software. This program makes my computer turn off in less than 10 seconds from hitting the confirm button on it. This occurs with CPU at base clock too. Anybody have any solutions to try or do I need to get a new CPU?
If anybody finds this and has the same problem: Check your core voltage. I updated BIOS and my core voltage was wrong, changing core voltage to 1.2V fixed it. I am not sure if the BIOS update or the core voltage was the fix but one of them fixed it and my computer no longer crashes under CPU intensive operations.
I re thermal pasted and cleaned everything when I replaced PSU. All fans work. I really don't think it has to do with thermals considering CPU can be cold and will still crash in 10 seconds of running Prime95.
Well updating the BIOS has essentially bricked my computer. BSODs almost immediately after startup and have gotten no less than 6 different BSOD codes. Microsoft support is **bleep** clueless. ASRock support hasn't replied, but something is seriously wrong with something in my computer, can't even get to desktop without a BSOD.
The BIOS update, if applied correctly, should not have caused you a problem. The motherboard, or memory, or processor could be failing. You are dealing with a system that is almost a decade old.

I am aware that the BIOS update is not the problem, merely a cause. Windows support says sounds like a hardware thing contact your mobo manufacturer, ASRock says sounds like a Windows thing. Intel support won't let me contact them because my CPU is too old, which I understand. I'm both annoyed and glad that I now have a reason to upgrade half my system lol.
Due to this product being discontinued, Intel Customer Service no longer supports inquiries for it, but perhaps fellow community members have the knowledge to jump in and help. You may also find the Discontinued Products website helpful to address your request. Thank you for understanding.
