Problem description:
This has been happening on and off for some time but is starting to get worse over the last week or so. After playing a game for about 15mins or so my monitors will go black and the PC becomes unresponsive. I can still hear game sounds but I'm forced to manually reboot the PC. Only games I play are Overwatch and Dota2, it happens with both. It also happened on a couple of occasions playing BF1 when I played it. it doesn't happen when I play Hearthstone (I guess I play that as well),

Attempted fixes:
-A rough clean out of dust last time I opened the case (about a month ago)
-Reinstalled GPU driver using DDU
-Tried playing games in fullscreen instead of windowed fullscreen
-Changed the install location of the games I was playing
-Installed afterburner to see if anything stood out. I can't really understand the logs, but here is some screenshots from my last session leading up to a crash.

I've done a ton of googling and i certainly don't appear to be the only one having the issue (there even seems be some on this very page) but nothing has really helped. The common suggested solutions are PSU and Overheating, niether of which I believe is the case. My PC doesn't eppear to be running hot and my PSU is only a couple of years old and a reputable model. I've seen a few people have fixed the issue by flashing the BIOS of the GPU but I'm unwilling to try that until someone can educate be about what that process (GPUs have a BIOS???) is and provide me with an update resource (the posts are normally 18-24 months old so I always doubt whether it's up to date). Here are a couple of examples:

If the system was working stably initially then it sounds like a hardware failure. The motherboard is pretty old so it could be failing. It's unlikely but still possible that a PSU can fail after only 2-3 years. Same thing with a GPU.

I'd check HD health using the portable zip edition of CDI:

Check RAM health by running this overnight some time:

If both of those are okay I'd try a new PSU/GPU. Maybe someone has GPU bios advice but I've never done that.

I opened up the case a couple of nights ago, took out the video card, wiped out some dust and re-attached the video card. PC has been stable the last couple of nights since, with no crashes whilst gaming.

Thanks for the advice though, I'll bookmark the thread so I can come back to it if the problem returns.

Are the any utilities for monitoring power draw to see how much power my system is drawing?

Yea, but the ones I've seen aren't perfectly accurate. Using a physical power meter is superior:
