My PC with installed Ubuntu 20.04 keeps rebooting.
Before 20.04 LTS I had Ubuntu 21.04, which had the same issue, which is why I decided to install previous version.
I tried to ground it in the office. It didn't help. One day, I even took it home from the office, I connected it at home with another power cable. It still rebooted several times. So, probably, it is not static electricity causing reboots.
I tried to run it without video card. It kept rebooting.
I inserted RAMs into different sockets. It kept rebooting.
I plugged my PC into UPS. The same.
I brought it to the service. They tested my PC for two days. They experienced same problem. Their checked hardware, said that it was ok. Installed windows on the same SSD, and there was no reboots with it. Then they somehow upgraded my Ubuntu. I am not sure what they did. But after that, they say, they did not experienced rebooting. However, when I brought it to the office it rebooted again.
I have 32 Gb of RAM, I had 2 Gb of swap which I increased an hour ago to 16 Gb, but it didn't solve problem with reboots. I have a NVIDIA P106-100 graphic card with 6Gb memory.
Time between reboots is random it can be 2 minutes or 12 hours. I am newbie in Linux, so, please, tell me what commands I should execute to provide you with needed information. Thanks for your help and time!
