PC won't boot, EZ Debug LED CPU indicator on

[asernag]

Hey everyone,

 

So I ran into some trouble with a build I finished last month. The specs are as follows:

 

Motherboard: MSI MPG X570 Gaming Edge Wifi

CPU: Ryzen 7 2700X

RAM: Corsair Vengeance RGB Pro 2x16GB DDR4 @ 3200 MHz

GPU: Gigabyte RTX 2070 SUPER Gaming OC

SSD: Crucial M.2-2280 NVMe 1TB

HDD: Seagate Barracuda 3TB SATA @ 7200 RPM

PSU: Corsair RX750W

Case: NZXT H510

 

The problem happened today while playing Rust. I have had no problem with the build for the entire month when randomly the screen froze, along with the RGB fluctuations on the rest of the setup, and I noticed the EZ Debug LED ineicator was on, with the CPU being "at fault". The only change I made in the BIOS was enabling the XMP profile to enable the correct frequency for the RAM.

 

I have tried basically everything so far: I cleared CMOS using the MSI manual, to no avail. I also changed the power outlet I was using without any change, and checked that every pin was connected properly. I also removed and reseated the RAM, and checked the CPU pins, with no error found anywhere. All of these changes led to the CPU LED indicator turning on on the debug indicator, and the PC does not boot and sort of cycles through the boot phase.

 

Where it gets interesting is when I remove the RAM sticks, which leads to the debug indicator passing the CPU check successfully and getting stuck on DRAM (obviously). This leads me to believe the CPU is not the problem. When I slot in any of the sticks of RAM, however, the EZ Debug indicator once again signals a CPU fault.

 

At this point I am just baffled as to what it might be, as it doesn't seem to be the XMP change (cleared CMOS had no effect), the CPU is installed correctly with no bent as well as the RAM, but the RAM situation with the indicator is wonky.

 

Could anyone provide any tips as to what I should try or do next? I will be trying each component on a friend's build but that will be until Sunday evening.

 

Thanks,

Adrian

The ram could be the issue here.

Hey all, a quick update on the situation.

 

I flashed the BIOS to get it to be compatible with a Ryzen 3 2200G, and the PC successfully booted up without issue. I then tried the Ryzen 7 2700X in another X570 board (Steel Legend) and the same Debug LED lit up, which leads me to the conclusion that the CPU is indeed the issue.

 

However, it is unclear to me why this happened, and I would like to try and avoid it in the future. Does anyone have any idea as to what my have caused it?

Hey @asernag

I know that this is old thread so ill bump it with my issue. I have read the post above and same thing happened to me with my Ryzen 2700.

PC was powered up idling for an hour or two when I came back I noticed that all of my fans were at max speed and PC was completely unresponsive. After I power cycled the PC only thing I could do was go into BIOS. Every time I tried to boot (USB KEY, SSD1(Windows), SSD2(Linux)) it would instantly turn of keyboard and mouse and EZ Debug CPU LED on MBO lit up.

So I have tried the regular approach unplug all etc. Tried new PSU, borrowed RAM from other PC I even bought new MSI MPG X570 Gaming and the issue still persisted. So in a nutshell I think this things happen. My CPU was always on stock settings and temps newer went above 65°C under load.

The RAM that you are using must be listed on your motherboard's Qualified Vendor List (for your specific CPU) in order to guarantee stability.

Just a quick update, I have RMA the CPU directly from AMD hence the shop where I bought it went bust.

They tested it and it was the CPU. CPU replacement is on its way and should arrive within 5 working days.

@Breeksta I agree to be sure its best to use memory that was certified by manufacturer in my case I have Patriot Viper Elite 8 GB DDR4 2666 MHz and they still work without any issue (they are not on the vendor list though), tested them on the new system.
