Have you updated the bios prior to upgrading your proccy?

Try to replug/ reset your monitor or use another port / cable .

Have you updated your drivers recently? maybe it's a driver issue...

GTX 1650 Super or RX580

problem solved guys. replaced the psu.

Went for a Seasonic Core GX-500. Thanks

Nothing worked on the software side. Can you guys recommend a good PSU for my system?

Maybe you're using the processor's integrated graphics. Or your card has just given up.

I already did this. Still the same This too, passed all test. Now I'm trying to disable amd's performance boost in bios to draw less power and more headroom for the PSU (assuming it's the culprit).

Unfortunately, it shut off again. Help guys

Did it, no shutdowns since and its been 10+ hours already, will keep you posted Thanks!

Yup. problem still persist

Trying it now. Will keep you posted.

So my newly built PC started randomly shutting down almost twice a day and from what I observed, it does it when the PC is either idle or underloaded but seems fine when gaming and doing heavy stuffs. Temps are also fine across the board. Everything shutdowns except for the usb ports. EDIT: And it doesn't turn back on unless I unplug and plug in the pc again.
