Hi all,

I need help booting a computer :(... I bought all these parts new for a workstation but all I get now is it boots and nothing shows up on the screen. I've built 3 PC in the past, not many, but I know I've seated the ram in the correct slot and CPU etc.

Here's what I've done:
Re-seat ram, and tried running single channel.
Took the whole motherboard off the case and make sure I didn't short the motherboard with a random standoff (although I'm short 1 standoff on the bottom left corner of the motherboard).
Took the battery out of the board for 5min and put it back in.
I tried putting in an old GPU to plug the monitor into, nothing worked.

Motherboard: Asus B365M-A
CPU: Intel i5-9400
Cooler: HyperX Evo 212
Ram: Corsair LPX 2666mhz, 2x8 GB
Storage: Samsung M.2 Evo 970, 500GB.

Any ideas?

Which BIOS version is your motherboard? The problem could be BIOS support for your CPU"s revision, PO, RO or UO.

Core i5-9400 (2.9GHz, 65W, L3:9M, 6C,rev.P0) - BIOS 0225
Core i5-9400 (2.9GHz, 65W, L3:9M, 6C,rev.R0) - BIOS 0606
Core i5-9400 (2.9GHz, 65W, L3:9M, 6C,rev.U0) - BIOS 0225

Hey thanks for the response!

I’ve never ran into that kind of problem, how do I check the motherboard Revision? I’m not sure how to update the BIOS to the correct version without another CPU? PCPartpicker usually tells me about having to flash BIOS if there is incompatibility, but this one didn’t have incompatibility on the page, but obviously I can’t rely on that 😂...

Unfortunately i do not think the PCPartpicker System Builder can distinguish which revision your Core i5-9400 is.
The revision of your CPU would likely be printed on the retail box it came in. The motherboard might be the same. You could try contacting Asus Technical Support on their website a giving them your motherboards serial number and they may be able to tell you which BIOS version you have.

I'm guessing the revision would be in the S/N of the Intel Packaging? I only see U0 in the S/N: U0V47N3104106
