What went wrong? ...Help solve my computer mystery

[crazyalbertan]

My main rig died the other day and I am perplexed at what happened as well as what the issue could be. I booted my computer like normal and it got to the windows 10 default screen where you put in your password. I went to click on my account to type in my password and the animation it does to change from the wallpaper to the input box stuttered like a game going like 5 FPS. Then once it finally got to where you could input the password before I could the screen went blank and I lost video signal. The system did not shut off and looked like it was still running normally. I manually powered down the system and tried to reboot but could not get it to POST. I cleared the CMOS, reseated the RAM and GPU, I even removed my R5 1600 to check for any damage to the CPU put everything looked normal. I reseated the cooler and tried again to no avail. I noticed at this point that the debug lights are lit for DRAM and CPU. I don't have another B350 MOBO around to use to test the CPU but when I put my RAM into my working intel system it wouldn't boot and it's RAM debug light was on as well. I tested the GPU it works perfectly and appears to be unaffected as well as the boot SSD. I am at a loss at what to do at this point. Should I RMA everything? Some parts? All these components are less than a year old and I need this rig to do my video editing. Any insight, or suggestions would be appreciated

I think RAM is likely to be your issue. Unless your Intel rig is DDR3 and you somehow managed to get DDR4 into a DDR3 socket.

The intel system is Kaby Lake based so the DDR4 shouldn't be an issue. I haven't tried putting in a different stick into the Ryzen system yet, could the RAM cause a CPU debug light to illuminate?

Try just one stick at a time and try different slots too.

It's unlikely that all of your ram is dead so you can find out if the CPU is okay this way

Well, unless that's one 8gb stick.. then you can't really do much but RMA it and try another stick.. Then if it still won't post, try to RMA the CPU.
