Is my motherboard or processor dying?

I have the following system running TrueNAS (cannot remember the version as I installed it in 2019):

Motherboard: Intel S1200KP
CPU: Xeon E3 1225 v2
RAM 8GB ECC
TrueNas is running one a USB pen drive

Everything has been fine for the last few years. Recently I noticed that my NAS drives were not showing up on my network. Re-booted the NAS and they re-appeared. This happened a few times.

However, on re-booting, I get the system beeps for no graphics detected.
I initially used the onboard graphics to set the BIOS to boot into the USB drive.
But now if I connect a monitor I get a blank screen and the beeps to indicate no graphics. So I am thinking either my motherboard is faulty or the CPU?

Is it time to get some new hardware or try an PCI graphics card?
Hard to diagnose as I cannot see the BIOS as I have no display whatsoever.

Also now takes a few (blind) boots to get my NAS drives to appear on the Network.

Any help or advice appreciated

Welcome to the TrueNAS forums!

Backup you configuration as soon as possible. Then make or verify your backups.

I would guess your “USB pen drive” is failing. Try replacing it.

And of course the old standby of blowing out all the dust. Plus, re-seating all the removable components.

Thanks Arwen

I know I backed up the config when I set-up TrueNAS so just need to find it!!
Its a very simple NAS with 2x 1TB hard drives. No RAID etc
So worst case I can re-create and re-mount the drives.

Actually the “no graphics” beeps come before the USB pen drive is being read so must be something else wrong no?

Just an update:

I think the motherboard (or CPU?) has developed a defect as the onboard graphics just does not work. So I moved everything to a new machine with:

MB: Supermicro X11SSl-F
CPU: Xeon E3 1220 v6
RAM: 16GB of ECC UDIMMS
OS Drive: Lexar 128GB Sata SSD

Moved my hard disks across form the old machine and got every thing to work in FreeNAS 11.3

Just upgraded (manually using the tar file) to TrueNAS 12.
Going to readup on TrueNAS for a bit before taking the plunge and getting current on TrueNAS 13.

I have to say its a good thing the MB has the IPMI feature - that is very cool. I could not get the VGA connection to work even though I used a VGA cable and display with a native VGA port. Could be the cable is defective as its a really old cable from before the days of DVI. But the IPMI features allow everything through remote connection - yay! So no need for another screen even.

Also thanks to Arwen who suggested the USB pen drive was dying as it was dying as evidenced by warnings from FreeNAS.
