My desktop in my signature is not powering on. I have tried changing the cables which are working fine as monitor is turning on but the Cabinet is not turning on.
What to do?

Is there a way to bypass the psu just for checking purposes like powering the mobo without the psu.. i think psu converts ac from our current to dc in mobo

At a very basic it could be faulty power on button on cabinet! Just swap Power & Reset connectors on mobo and check again using Reset button as power on.
Reconnect all PSU cables again.
Use PSU paperclip test and check if PSU starts or not as a standalone device. If it does not, it’s clearly faulty. Check net if you do not know how to do paperclip test.
If it does power on, it could mean either faulty mobo circuit or may be that PSU is now no longer taking the load of the system. Start with minimum components and check again.
To test PSU/Mobo, you need another healthy PSU.

Swapped the power and reset buttons but nothing happened.
Reconnected all cables but nothing happened.
For the psu paperclip test I didn’t had a paperclip but i used the rings on a small keychain and moulded it almost into the shape of a paperclip and just when i was about to quit testing since the almost moulded ring wouldn’t do anything i saw the cabinet LEDs light up along with a fan confirming that psu is ok.
Now what should i do?

So it seems now you have a system that just powers on but does not POST anything on monitor?
Re-seat RAM, GPU, Storage etc. Turn off the PC from Mains and long press Power on button for 30 - 40 seconds to remove any static charges on the board and retry.
If above does not work, clear CMOS by shorting the RST CMOS pins on the mobo for 10 - 15 seconds. However when you do that make sure Mains supply to PSU is OFF.

Gear up ...
Take it to a local shop, they might diagnose it for 500-1000.

So till now nothing worked even after so many tries. That’s why I brought a PC from workplace to test different things.
A new motherboard, processeor (AMD Pro A10 9700) and SMPS coupled with old graphics card, HDD, NvMe SSD in the assembly and the system won’t boot.
System won’t detect the NvMe, won’t detect the bootable HDD which already has OS installed apart from the SSD, won’t even boot a bootable USB Flash drive and won’t even boot from an old DVD of Win7 even after setting the boot priority correctly. I’m having enough of this PC sh!t going waywards even after spending good amount in hardware. The new Mac Mini is attracting me so much that i’m considering to switching unless some miracle happens with this PC.

I did take it to my vendor at office he troubleshooted but couldn’t identify the exact issue. he suggested problem with smps but i did the diagnostics mentioned above which were successful in proving that smps was ok. i don’t know what is the problem with the pc.
