Hi, I have a full node with 2 standards. They all seemed to boot up correctly and I even am able to log in fora moment and I get a spike in brains but the the fall node will reboot. Not enough time to explore what is happening. Samme behavior even if full node is by itself. Any thoughts?
The fan on my main cpu doesn't work. Can I get a replacement JDL2507S fan?
I'd recommend you to contact the support team of Futurebit or reseller where you bought your device through E-Mail.
Could it be an issue with SD card needing to be reflashed?
It is very possible that you have a microSD wear issue. I'd even just go get a new microSD after 2 years, to be honest. Look for high endurance models like Samsung Pro Endurance or an equivalent by SanDisk. Normal microSD cards are often made for just a few 100,000 write cycles, which can be exceeded quickly when they're used as a single board computer's main drive, where you might get a lot of writes in some areas of the memory.
Re-flashing can be a good temporary fix, but you'll run into similar issues much sooner than if you were to just get a new card.
You could still use the old / worn microSD for less 'mission-critical' stuff.
