I have an older g700 PowerSpec that has worked well for quite a while. Recently when I start to render a video using Davinci Resolve it runs for a while and then stops suddenly. I checked the unit using Cinebench and noted the same behavior after a short time running. Then suspected the power supply and replaced it with a slightly higher capacity unit. Same behavior. I’ve checked the temperatures and hardware and noted the GPU fans were running off/on and the GPU was at 55C. One of two fans was not running at all. I watched the unit with the cover off and when the PC stops, the fan on the cpu continues to run but the light around the fan goes off. I’m curious if the CPU is failing or if the graphics card is failing?
Overall, sounds like a motherboard failure. Most likely the chipset, based on your symptoms.
As for upgrading or replacing. The technology has evolved overtime, including the chassis. We use mostly Lian Li 205 Mesh on our G700 series now. I don't see that there are a lot of components worth keeping if you're doing a new build. Though you could build an B550/X570 platform and use that to verify the other components are working. Then you'll just replace the board. Use it as a second system, give it away or sell it.

Could you explain what you mean when you say it 'stops'? It's not powering off. Is the screen going black? Is the program crashing?
The screen shuts off - to black. The processor fan light goes off but the fan continues to run. I have tried to run Task Manager, but it won't activate. Last night the computer did reboot itself following a Cinebench test when I was manually running the GPU fan at 50%. Monitored the CPU temp and watched it rise to around 70C. Overall processor load was pushing 80 to 90%.
Check your event viewer logs at the time of the crash. Custom Views - Administrative Events. What do you see at the time of the crash, before the Kernel PWR critical event?
Here's a snip of the Event Viewer Log:
Pretty sure the volmgr and EventLog error are going to tell us it failed to write an event from the failure. Indicates the drive is inaccessible, but typically with a drive problem you would hard lock, your frame buffer would freeze. The screen wouldn't go black. If you have another drive you can throw an OS on and test it's still worth checking that.
Question with the fan LED going out. This does come back on immediately after you restart the system, correct?
Correct, the errors stated that events could not be written, but the 'lock' occurs and normally does not reboot the system - i have waited several minutes.
Yes. theLED comes back on following reboot. I do not see any other lights go out on the PC. The OS drive is a WDC WDS500G2B0B which was replaced under warranty. I do not have a spare NVMe drive. I currently have about 174 GB available on that drive.
Hate to akk as this PC still has great performance (in general), but would it be best to rebuild with new components? Or, just get a new PC?
