RAM: TeamGroup ELITE 16GB DDR4 MotherBoard: BioStar B450MH ver 6.3 CPU: Athlon 3000G GPU: Integrated Graphics PSU: Vorago 600W RGB PSU Hi! This is a PC i was lent to repair, i have run the usual diagnostics (swap ram, reseat components, unplug and plug again), however, zero life, no fans spin to life, PSU doesn’t power on. I’ve noticed that the LED’s on the case turn on when everything is plugged in, but the power pins seem to not be working, i’ve tried swapping the reset connector into the power pins with no life still, i’ve tried shorting them, also nothing. I would really aprecciate some insight from experts, do i need to buy any other components? Here i attach some photos regarding this issue (At the moment the motherboard is out of the case, i’m trying to see if other power supplies can help, so far i’ve tried two with the same results.)

I fixed the problem, lol—I didn’t update the thread. Here’s what I did:
- Checked CPU performance on another board; it worked flawlessly, both CPUs and integrated graphics.
- Tested RAM on another board; also performed perfectly.
- Inspected the old PSU in the customer's PC. After shorting the green wire with a ground wire, it powered up and started. I saw many bent heat sinks, likely dropped, which might have disrupted power delivery and damaged the board. This led me to realize the motherboard was dead, drawing power but failing to supply it properly—maybe the PSU caused the issue.
- Notified the customer; a replacement motherboard is en route.
