VGA and boot LED not responding after power on
VGA and boot LED not responding after power on
Setting up a fresh setup for a family member this Christmas. Components used: Ryzen 5 5600G (bought from Memory Express), Asus Dual RX6600 (arrived today from Newegg via Purolator), ASRock B550M Pro 4 (ready for Ryzen 5000, box stamped, received Friday 12/03 from Newegg via Purolator), 16GB Corsair Vengeance LPX 3600mhz CMK16GX4M2D3600C18 (Amazon purchase), SN750 500GB boot drive (Amazon), and a 650w PSU Gold+Bronze (pre-built test passed, no post required). All power connectors are secured. Initial checks: CPU tested, memory in A2 & B2 slots, GPU connected, LED debug shows BOOT and VGA active. No post, black screen appeared. Fans spun on both the CPU cooler and GPU.
Steps undertaken:
1. Swapped DRAM to only one stick in the leftmost slot – no change.
2. Removed GPU, plugged in Display port cable directly to motherboard for iGPU use – no change.
3. Found online advice suggesting no SSD or NVME caused failure; installed NVME – no change.
4. Followed manual instructions to clear CMOS – no change.
5. Moved GPU to a secondary PCI slot – no change.
6. Swapped personal R7 3800X into CPU socket – no change.
7. Swapped personal RX5700XT into the first PCI slot – no change.
8. Swapped personal G.SKILL F4-3200C16D-16GTZRX (Trident Z 3200mhz 8GBx2) into slot A1 – no change.
9. Swapped personal RX6600 to verify it wouldn’t cause DOA – passed successfully.
10. Installed R5 5600G on the system to rule out failure – passed successfully.
11. Placed Corsair Vengeance LPX memory (one stick at a time) into slot A1 – passed.
12. Reinstalled and rebuilt all personal hardware back onto the motherboard – system booted normally. (Currently being used for this thread.)
13. Reinstalled all new components onto a new motherboard – no post detected. VGA and BOOT debug lights lit up.
Potential issues remain: only possible cause could be a faulty motherboard. I’m submitting a support ticket with ASRock and seeking further guidance or tips. Thanks.
Someone mentioned 650W is suitable for a modern gaming setup. For better performance, aim for 750W to 850W. That said, it’s not just about the number—consistent results matter. I verified this with all ten tests and confirmed it works as a top-tier motherboard.
Keep reminding folks that’s the same thing, and you’ll be a troll forever. I don’t aim to belittle anyone. A 650W power supply for a gaming rig was a concept from 2010 with no real foundation today. The next generation of hardware will demand even higher performance per watt.
