PC boots but no POST

[Maki Zenko]

It was started yesterday when I start 3d rendering on my pc (Maya 2014on Maya Software Renderer). It was stayed on for 10 hours (8 PM to 5 AM) I woke up to check the progress and turn it off and go back to sleep again. 

 

Afterwards, I woke up again and after I turned on my PC, something has happened. The PC turned on, the fans are spinning, but no HDD and Power Light LED on and black display

 

I did several diagnostics such as RAM, CPU, HDD and CPU and still no dice. No improvement

 

Also, the casing doesn't have built-in buzzer, which makes the troubleshooting even harder.

 

System Specs:
Mobo: Gigabytes A320-S2H

PSU: Corsair VS550 PSU

CPU: Ryzen 3 2200G 

RAM: 8 GB (Single RAM)

HDD: 1TB WD, 1TB Toshiba (small)

Display: Samsung HDTV LCD 

No GPU yet.

 

Thank you

Okay here is the only thing that could help. So unplug ur pc or just flip the switch on the psu. Wait 30 secounds and see if it works.

I did and still no changes.

Hmm try resetting bios to defaults.

I already use a jumper to clear CMOS. Still no effect

UPDATE: The PSU is the culprit! I replaced it with a newer one (Seasonic), but I bought the Corsair PSU last month (September), and still covered by a warranty of 1 year. 

 

EDIT: Corsair VS550 Grey (Tier 5)

Have you tried removing the motherboard from the case? To see if the pc boots up outside it. Maybe a screw is too tight and it's bending the mobo. Happened 2 me once.
