[SOLVED] A320M-K doesn't get an image but it gets energy of PSU ?

[blackknight19]

Hello!
I have the same trouble like this:

B350 pc mate motherboard won't boot or post with an amd a8 9600 cpu loaned from AMD

Everything turns on like it's supposed to, cpu fan, gpu fan, and leds turn on, but it won't boot or post and there is no display on my monitor. I have checked the EZ debug leds, and the boot and vga lights stay on. I don't believe my graphics card is the problem because it was working fine...

forums.tomshardware.com

I switched the motherboard on without a frame (black box). A fan is working, light-indicators are working too. But My computer doesn't show a picture in my monitor. A speaker (thing which make beeps) is absolutely quiet.
I think that my PSU doesn't get Power_Good to my motherboard. Am I right? However, this PSU is work. I use zm600-rs in my old computer today.

My configuration is:
Motherboard: Asus prime A320M-K, rev - 1.02, bios - 4022
CPU: AMD A8-9600 (for AM4 socket)
PSU: ZALMAN zm600-rs (600W). (I attached picture of it's box)
VideoCard: no (videochip is integratted in cpu)
RAM: DDR4 Crucial 4Gb-2133Mhz UDIMM 1.2V CL15, CT4G4DFS8213.C8FBD2

Welcome to the forums, newcomer!

How old is the Zalman unit? How do you still have that PSU? You should try and work with a reliably built PSU. What sort of units do you have access to? Also, your BIOS seems to need updating. You're on 4022, the latest is 5603, that's 18 BIOS updates to work your way through :/ Although the BISO you currently have will work with the APU on your motherboard. What ram slot are you working with?

Do you try to boot from HDD / SSD or USB stick, or just try to see Bios on screen ?

Lutfij, I bought Zalman in 23.08.2011. Zalman works in PC configuration with CPU AMD Athlon 4000+ (AM2).
I used this very very rarely because I had notebook. It has been from 2012 year till november 2019. I graduated in univercity for that time, and I did not played games.
Just now, I use this PSU everyday. I typed text, watched movies, listened to music, searched in web browser. This PSU is reliable.
I put RAM-card in each slot. It doesn't worked ;(.
I tryed to repair BIOS with function of "ASUS CrashFree BIOS 3" several number of times, but it cannot help. ;(

In user guide of A320M-K, in motherboard overview, I found:
"(1) ATX Power Connectors (24 pin EATXPWR, 4 pin-ATX12V)
These connectors are for ATX-power supply plugs. The power supply plugs are designed to fit these connectors in only one orientation. Find the proper orientation and push down firmly until the connectors completely fit.".
Notice: Zalman has form-factor ATX (not EATX).
Update: I used units to have access to MB: processor, motherboard, one RAM card, cooler.

Egda23, no. I didn't. I tryed to see bios on screen.

The Assus motberboard is new ?
Can you prepare a win 10 installation USB stick, and try to boot?

egda23, Motherboard (MB) is in ideal state and looks like new one. But, I bought this one from advertisement in newspaper.
Past owner told me that he bought MB in a shop (it seemed that). Testing to boot, he had my problem. He bought an other MB of Asrock built on A320 chipset. I thought that BIOS is problem. After trying to repair BIOS, as I said in previos message, I understood that problem isn't BIOS. ;(

No, I may not to prepare a USB stick just now. I am sorry! Preparing will take so long time (slow internet)... But I can do it if it helps. I will try... Thank you!
