Mining rig crashing

[BBozard]

Hello. I have a mining rig that crashes to the bios screen every day or so. It will mine fine from anywhere to 1-3 days then I will get a notification that its offline and when I look at the monitor it simply says "Asrock" like its trying to boot up but it never will. I have to unplug the rig and plug it back in to fix it. Any ideas? Its a really annoying problem.

Could be a riser going bad, or even the GPU.  Do you have a spare riser you can start swapping out one by one to see if the rig stabilizes?

Could be a hard drive getting ready to fail. Or are you using USB?

Here are the possibilities:

• It Boots up but doesn't POST, it wasn't the RAM or CPU.
• Could be the Power Supply - Monitor the voltages.
• A bent or broken SATA Cable (if you're using HDD or wired SSD)
• If it crashed due to CPU overheating, the system will shutdown, not restart. But did you properly applied the Thermal Paste? just to be sure.
• could be one of the GPU failing, or the riser is broken.
