ubuntu 20.04 frozen randomly

[Simon Zhou]

I am using Ubuntu 20.04 (dual boot with windows 10) on Dell vostro 7500, the whole system crashes randomly, the symptom is the whole screen frozen, the time on the screen is stuck, mouse cannot move, keyboard input is invalid. I think it is a kernel crash because sysrq does not work, which works in normal time, and /var/log/syslog contains no lines after the crash.

I tried reinstalling the os and switching my kernel version from 5.4.0-58-generic to 5.4.0-42-generic, but the problem persists. The frequency of crashing is one time per week before reinstalling and one time per day after reinstalling.

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1798961 described the same problems as me but it is about 18.10 and is closed.

I get the same issue on DELL Precision 7550 and I am sure I got it once also on a Precision 5550
