I bought an Optiplex 5040, with an i5-6500TE, and 8 GB DDR3L RAM.

When I bought it, I installed Fedora Server on it. It got stuck every few days but I could never see the error. The services just stopped working, I couldn’t ssh into it, and connecting it to a monitor showed a black screen.

So, I thought let’s install Ubuntu Server, maybe Fedora isn’t compatible with all of its hardware. The same thing is happening, now, but I can see this error. Even when there’s nothing installed on it, no containers, nothing other than base packages, this happens.

I have updated the bios. I have tried setting nouveau.modeset=0 in the grub config file. I have tried disabling and enabling c-states. No luck till now.

Would really appreciate if anyone helps me with this.

UPDATE:

  • I cleaned everything and reapplied the thermal paste. I did not see any change in the thermals. It never goes over 55°C even under full load.
  • I reset the motherboard by removing that jumper thing.
  • I ran memtest86, which took over 2½ hours. It did not show any errors.
  • I ran a CPU stress test for over 15 hours, and nothing crashed.
  • I also ran the Dell’s diagnostic tool, available in the boot menu of the motherboard. The whole test took over 2 hours but did not show any errors. It tested the memory, CPU, fans, storage drives, etc.

    The boot drive is an SSD, which is not in any RAID. I have another HDD connected via SATA. Another HDD connected via USB.

      So 2 HDDs one SATA and one via USB in RAID? Can you remove the RAID drives and test it out?

      Also what size are the drives and what’s their capacity?
