I recently lost my motherboard that is an ax370 gaming k5 by gigabyte. I have no idea what caused it. I hadn't overclocked ram, cpu or gpu. My system just blacked out and when I tried to turn it on again I could see smoke coming out from the motherboard (area between the back USB slots and the cpu where you have bunch of ics with a bolt logo on it. I switched it off immediately and opened up the back panel of the cabinet and could see some round shaped loop marks all over the same section. I need to know what caused this. I am kinda clue less. I check my Temps regularly and they were fine as always I also clean my system every 2 to 3 months. I have power fluctuations where I live but i have a decent ups which is also plugged to a spike guard to avoid issue from power surges. I hadn't done anything new software or hardware wise. Can you guys help me figure out what caused this and also if it's safe to put my cpu a ryzen 1700x, gpu, ram sticks and psu and liquid cooler h100i on a new motherboard for testing or will I risk damaging the new motherboard if I do. I don't have access any other motherboard or system to test out my psu cause of quarantine. Here are some snaps of my mobo https://ibb.co/LgxGZGW https://ibb.co/p0JD3TG https://ibb.co/f2mMQJs
 
I think the most likely culprits are the motherboard or the power supply....and I think most likely the motherboard.
I would replace the motherboard.
If it is a good quality PSU that I wanted to keep....I would test it before I connected it to the new motherboard to make sure the voltages were correct and stable.
If the PSU is cheap, or questionable, or old...I would also replace the PSU.
I think that with a new motherboard and good PSU (either a new PSU or if you can confirm yours is good by testing it first) there is little risk of damaging your other components.

The psu is cooler master v750 which is 2 years old... And also is there any chance my processor might be damaged.. And how do I test the psu without connecting it to a different pc?
 
"And also is there any chance my processor might be damaged.. "
I think there is always a chance...but in this case I think the chance is slim. It's not real common for a failed MB to take out the CPU in my experience.

Here is how you test a PSU.

This test isn't super thorough because it doesn't test it under load....but I think it's a good enough test to confirm it won't fry your motherboard.
