My PC just restarts randomly as if I have pressed the restart button. There's no actual pattern on when these reboots happens but here's few things I have noticed:
1. Reboot occurs when I launch an app/ open a new tab on browser (LOL) . This app doesn't have to be the same, sometimes this will lead to the reboot and sometimes it doesn't. (Generally speaking, this happens when I do tasks that are compute intensive + memory intensive)
2. This reboot doesn't happen when I am doing a very low (memory + compute) intensive tasks. Like editing files on vim.
This sudden reboot was happening like once a week, now it has increased to happening like 10+ times a day.
Here are My system details:
Kernel: 5.16.14-arch1-1
CPU: Intel i5-7400 (4) @ 3.500GHz
GPU: NVIDIA GeForce GTX 1050 Ti
Memory: 11907MiB
More background about my PC:
1. I haven't made any hardware changes recently (last was more than 1 year age).
2. I monitor the cpu temperatures they are not that high when these reboots happen around +75°c.
Though my PC is dusty which leads to high temperatures, when I perform some builds.
Due to this my system crashes with over temperature error. (I am currently cleaning my PC to resolve this issue.)
3. After doing some google searches I found, PSU can be the cause of these random reboots, since my PSU is fairly old.
Though I am not sure If this is the case in my situation.
My Questions:
1. why these reboots are happening?
2. How can I debug, which hardware/software is the culprit?
Any help is really appreciated. I am in desperate need to resolve this issue.
Many Thanks.

How can I debug, which hardware/software is the culprit?
Try to reproduce the issue and then upload the output of
journalctl -b-1 to a text hosting service.
Maybe something gets logged before the system loses power.

Thanks for replying!. Here's log: https://0x0.st/oNPS.txt. Crashed at 15:50
This reboot happend: when I open a new tab (gmail) to be specific. To reproduce it I tried various stuff like, launching multiple apps, opening multiple tabs, etc but during that it reboot didn't happen . When I suddenly opened a single tab the system rebooted.

I'm not saying it is this, but if this line from your log...
Mar 18 13:14:04 paradox kernel: DMI: System manufacturer System Product Name/H110M-CS, BIOS 3601 12/12/2017indicates that you have this specific motherboard - https://www.asus.com/supportonly/H110M- … Desk_BIOS/
then (if you "expand all" on that page), you will find several newer bios versions than version 3601, some of which are tagged with "improve stability", so after checking that is the correct motherboard, a bios update might help.

If you have not done this already, you should check if both your RAM and your storage devices are in a healthy condition. Faulty hardware is often the cause of random reboots.
