I did

In both circumstances but yeah it goes off when under some , not much processes like illustrator or pubg download

Amd x4 740 , 8gb ddr3 ram , Onda a58p+ mobo, gt1030 , antec atom 550 watt psu, 120 gb maxsun ssd and 7.2k hdd .and 20inch monitor You know I took it repair shop several time's and left it there for whole 24 hours and what the repair guy says is it completely works fine said he ran it for 8 hours he played games and watched movie's but when I try to run it in my house it just shows no signal after 20 minutes or 1 hour it's random.. The disk reading indicator light on my case blinkers for a long time and then it promptly shows no signal and stops blinking, While all the fans still run of all components Yeah maybe one thing it is plugged in a ext.cord along with a tv and set top box Maybe it's not getting enough wattage . Big thing is working fine in the repair shop but not in my house

Cpu temp idle around 36-40

My pc boots up fine and runs for some time easily but then it shows no signal and pc shuts off on the inside but all fans still running, i know because my pc doesn't show up in mobile hotspot connected device when pc shows no signal and the disk reading signal light on case blinks for long time and then shuts off or no signal, but fans still run

They checked with monitor too everything runs fine

My pc shows no signal randomly after 1 or 2 hour use and sometimes instantly. The temp's are only around and below 40* and my pc just keeps fucking working fine for 8 straight hours in the repair shop and after 4 trips to shop he says my house may have power surges and spikes and I should buy one surge protection spike guard ext.cord maybe I should I see those surges too.

How ? And if that was the only case even speakers playing sound would stop and the only way to get back is to totally restart my pc

My pc ran completely fine for 2 hours straight when I took it to repair shop and the guy said my pc is completely fine. But when I run it back at my house the monitor shows no signal randomly at any random duration like 20 min or 1 hour still when cpu fan, gpu fan , psu runs and monitor ran absolutely fine as it did on shop , don't know what's happening

Thanks for your help but now I have no choice than to turn back to windows because I cannot find a single compatible wireless adapter for Linux kernel 5.4. In India

Thanks. I kinda new but was in rush

I am in the market , can't check but when I checked it was gnome version 3.04. Are they same

Temps are idealing 57 -60 and it's not black screen the monitor shows no signal

It just gets no signal I think I should update drivers

My pop os pc shuts down suddenly, the cpu, gpu,psu are still running so this might not be hardware problem and one more thing What kernel version is the latest pop os 20.04.
