Ok I've a customers build that won't post when I power it on. Firs thing I did was to get a new 600W corsair PSU as I thought that was the issue. Nothing happened again. No lights coming on to the mobo with teh new PSU.

I did the "paperclip" test, albeit with a special proper gadget to these and the PSU's, both, are fine. New PSu not needed then.

I thought it must be the MOBO so sent it off as an RMA. Got word today that it posted fine and is being returned :/

That leaves RAM or CPU am I right?

Ram is 3000Mhz - Team Group Dark Pro 16GB (2x8GB) DDR4 PC4-24000C15 3000MHz Dual Channel Kit - Black/Red (TDPRD416G30

CPU is - AMD Ryzen 5 Six Core 1600 3.60GHz (Socket AM4) Processor - Retail

Graphics card is MSI 1070 Armour

How can I test the CPU and RAM with the problem of the MOBO not posting?

Would a faulty CPU stop all lights getting to the MOBO even if broken?

Need some help here...mobo enroute back via post so I dont' actually have the mobo at hand. Just going by the OCUK email saying it posted fine when booted
 
A faulty CPU would stop a system from successfully passing POST since it would be one of the first items checked and if I'm correct, if it is the faulty component you won't get any notifications unless there is a Dr. debug on the board although if you don't have one connected plugging a beeper speaker into the motherboard would help if it is producing an error code.
 
Has it actual got a new enough bios - some am4 boards couldn't post ryzens out of the box. (Although you would think ocuk would update the bios if this was the case)
 
It worked fine for 6 months. It just suddenly stopped working. No lights to the mobo, nothing. Hence me thinking it was a PSU issue. However the PSU works fine (as did the new PSU I bought) and if the mobo, and I quote,

Dear Mr Paul McCaw,

The product MB-323-MS on RMA340929 has been returned to you, this will be sent on a new order with order number 5301429.

Here is the technicians Test Report:

"Motherboard posted fine. Updated the BIOS to the latest version and POST tested again works fine."

...works fine then what's the score?

They think it works fine which then leads me to think has the CPU died, or has the RAM gone faulty?What else could have caused the mobo to stop getting any power into it?

When the system was first built in Oct, I had to get new RAM as a replacement as I had a faulty stick. The new RAM worked fine though, running at 2666 (couldn't get it to run a 3000) Since then, the PC has worked just fine. It just suddenly stopped working one day when the customer was browsing online.

Is there a way I can test the RAM and CPU without having to get a new CPU and RAM to check in the mobo that's being returned? Other than having to buy something to test it on

Ah apologies, assumed it had never worked.

Presumably you have tried it all outside the case? (just to rule out shorting etc)

Just seen your post for a pc speaker - worth a try. Assuming modern boards still work the same as older boards, booting without ram installed should give you some beeps (assuming cpu works), otherwise cpu is likely suspect.
 
You tried just one stick of RAM, in each of the sockets, do this with both sticks individually to see if a stick is faulty and/or a RAM slot as well?

Tried a different GPU? Different PCIe slot?
 
Through the kindness of another member, I got a mobo speaker sent to me. Returned MOBO should arrive tomorrow and I can try it out.

Do any of you think that it's ok to ask to borrow a cpu and/or a stick of RAM from someone (for a few beer tokens) to help test (mobo posted fine during RMA testing) or should I fork out for a single stick of RAM to test, if that stick fails then RMA the CPU without actually testing the CPU anywhere else?

Just means I@ll be stuck with a single stick of DDR4 if I have to buy one. I don't know anyone near me that is into PC's as much that can help me with borrowed hardware.

Is it considered "snide" to buy a stick of RAM, use it to test the system them return the new stick of RAM for a refund?

Thoughts?

to test the motherboard with and then return 1200 for a refund if the Ryzen 1200 works, but the 1600 chip doesn't? Then RMA the 1600 chip?

If you are doing this as paid work then you should consider buying a stock of replacement parts in order to be able to diagnose this kind of stuff. Your customer gets faster better service without waiting for RMAs to come back. Plus some poor sap doesn't end up buying a part you used for testing. Plus there is a real risk that the mobo could have a short and be frying every CPU put onto it. You buy a cpu, 'test' it still doesn't work and then you send back the now fried cpu.

Get the parts, it will save you heaps of time in the long run.
 
It was the graphics card the whole time ffs!

Tried it in my own and it wouldn't boot. Tried my card in his pc with it all built again, works fine.
 
glad to see you found the fix.

JayzTwoCents posted a vid not long ago about a build turning straight off after a second, dodgy sata power to an SSD prevented it from booting, In the world of Computers it can be anything, just an process of elimination and remove accordingly.
 
Yeah. I wasn't comfortable with the buying to test, then ask for a refund. I think it's a snide thing to do myself and wasn't really wanting to do it. Glad I found out it was a GPU issue that was fixed.
