Recently got a new Gigabyte b450m, Ryzen 5 2600x and 8 GB of ram with my older components, a 1050 Ti, a Kingston 240 SSD and a 1 TB HDD and a Segotep SG-D600SCR, 600W PS.

Right after getting the new components i built the PC, ran without any problems for a few days after that it started crashing when being used for more hours, after that it started crashing more often, in minutes after being on. The thing is if im playing something or at least have a game running in the background (dont have to be playing, just main menu) the PC won't crash.
The PC being idle or when i watch movies/youtube will crash, gaming on it wont make it crash.

After a few more days it started powering up (the fans, leds are on and working, sometimes the mouse and keyboard leds are on too) but not displaying anything, what i had to do was keep restarting it and eventually it will turn on.

What i've tried: turned off fast startup, cleaned it (tho it was pretty clean already), chanced power options (tried all of them and also a few power changes i found online, went back to ballanced), unplugged the CPU cable from the motherboard then plugged it back in (wich made the PC turn on, but now that wont do it anymore), got the mb battery out for a few mins and put it back in, got the ram out and then back in, used ccleaner for software cleaning.

Right now i'm using the PC and have Dota 2 runnig in the background so it wont crash.

I will try to. But what doesnt make sense to me is why is it not crashing while gaming and it crashes while im doing usual stuff since it should use more power while im playing something.

I "fixed" the not always displaying something when i turn it on by turning off the extension cord for a few seconds before turning on the PC. Wich makes me thing it could be the extension cord, ill test that.

Also just reinstalled the windows just in case the crashing part would be a software problem, but it still kept crashing. Tho after leaving the extension cord off over night it apparently stopped crashing, it was on for hours and then i had to turn it off to get to work.
