No POST

[Robinsony]

Hi LTT Community,

 

I'm in the process of building a computer (https://uk.pcpartpicker.com/list/DkQzxY) for my Step-Dad, he wanted to buy a pre-built one but I advised him that for the price range he was looking at, he would be better off having me build one.

 

The Crosshair VI's Q-Code LED's (below the main display) help by indicating failures for DRAM, CPU, VGA and BOOT. My DRAM one is lit up. The post code is 'Ad'.

 

It isn't posting, there is no visual output on the display and I can't get into the BIOS.

 

I've moved each DIMM individually into each slot, each time I try to POST the DRAM error indicator still lights up.

When I try to boot with no RAM the indicator still lights up but the POST code is '4B' (which is to do with RAM) and the light still remains on (although I suspect that is due to the lack of RAM)

 

I have no other motherboard to try and no other DDR4 I can use to troubleshoot the problem.

I have no reason to suspect any fault with the CPU as the LED indicating that the CPU is 'ready to boot' is green and the LED next to that of the DRAM one isn't lit. 

I have swapped the GPU for a GT610 (so that the GTX 1070 isn't what is failing to output a signal. Additionally, booting with no GPU yields the same results.) and I've changed the HDMI cable and monitor to ensure that they aren't at fault.

Still nothing.

 

I could try swapping the PSU from my PC but as I have an LGA1150 system the Motherboard and RAM can't be used as it is DDR3.

 

If anyone has any troubleshooting steps I could try that would be greatly appreciated.

 

I have included some pictures, I'm not sure if they'll help.

 

Thanks,

Sam

 

Ps. I was going to build the PC on Friday however half way through the build I was going to install the CPU Cooler but stupidly forgot to get AM4 mounting hardware for it. I tried to post it very quickly without a cooler to ensure everything was working but that failed. I presumed it was due to the lack of a cooler and that it was a safety mechanism not to boot but I did not investigate it further. I presume that the memory was at fault then aswell.

 

**EDIT**

The RAM is Corsair Vengeance LPX DDR4-2400, which is advertised as supporting Ryzen.

Try with one RAM stick

clear CMOS

is the RAM on the QVL list?

I've cleared the CMOS and tried with one stick already.

 

The model is on the QVL list (CMK16GX4M2A2400C16), but what I didn't realise is that the Version (Ver5.29) isn't on there. Could that be what is preventing the POST?

it should totally work.

I see no reason for it to not work.

Do you reckon it may be worth flashing the BIOS to the latest version? 

 

**EDIT**

Just realised I can't if I can't access it in the first place

I'm basically sure that if the BIOS was flashed to the latest version, it would POST (as long as the RAM isn't actually broken)

 

maybe it's just taking a while? wait like 5 mins for it to post and see if that works. sometimes the DDR4 training takes a while, and sometimes the motherboard even fully shuts down a few times on AM4 on first boot.

 

so clear CMOS, hit the power button, and wait 5 minutes.

I'll give that a try. Because the POST code is 'Ad' ("Ready to boot event") that may be the case.

It hasn't worked. Ill see if I can get the BIOS Flashback to work.

some boards actually can flash BIOS with no components installed check if yours is one.

I've given it a try and it hasn't worked. I'll try and see if I can get some DDR4 to try, maybe from a local store or something.

another question:

Why such a highend board?

if you're trying to be price-competitive with a prebuilt, just get a cheap board, shitty case, and save a ton of money.

The board advertises AM3 cooler compatibility so we decided to It instead of waiting to get the mounting hardware from the cooler manufacturer that could have taken weeks. The build is needed as soon as possible.

Why not just use the stock cooler lol

The 1700x doesn't have one. A 1700 none with a stock cooler + b350 board would have been a better choice but it may be too late now anyway.
