Ubuntu 16.04 crashing in unusual way

**BryanPotts** · September 18th, 2019

My ubuntu 16.04 installation periodically freezes by looping the last second or so in audio while the screen is completely locked. This repeats for maybe 15-20 seconds than self-reboots.

I've tried swapping out the PSU, ubdating the GRUB settings by changing...

Code:

GRUB_CNDLINE_LINUX_DEFAULT=quiet splash"

into

Code:

GRUB_CNDLINE_LINUX_DEFAULT=quiet splash intel_idle.maxcstate=1"

However, this has not resolved the issues. dmesg doesn't seem to show anything after a crash, but after the next crash I can update the post with the results. I've also read that a similar issue can be caused by a bad GPU. However I'm using onboard graphics and I want to make sure, as reasonably possible, that it isn't something else before I dump the money on a new MoBo.

Thank you! Any extra information I can provide that is needed I will post as soon as possible.

Onboard GPUs are usually in the GPU, not on the motherboard. I've never heard of a failure.

Check all the system logs in /var/log/ for issues.
Also, it sounds like a low-memory situation. How much RAM and swap is configured?
