Rebuilt Computer stopped and won't reboot

[scottpar28]

I rebuilt my computer with new ryzen 5 CPU, new mobile gigabyte gaming 3 and msi rx380 GPU . It booted up great and stayed working for a few weeks, then added the new you last week and still booted up fine. Tonight the computer screen just went black and would not restart when hitting the reset button. Turned it off and back on and I see the CPU LED light is on solid but flashing intermittent between CPU and DRAM LED light. I removed the heatsink and carefully looked at CPU, all pins intact

Any suggestions? Did I fry something?

What are you saying you added last week?

Last week I added the new video card and it started up great with no issues

Have you cleared the CMOS? What is your power supply?

I pulled out the CMOS battery for 2 minutes. I have 750 w power supply.

You said "I see the CPU LED light is on solid but flashing intermittent between CPU and DRAM LED light".

It's not clear to me what you are saying. Could you describe again what the Diagnostic LED's are doing?

On the motherboard the CPU LED light stays solid but then flashes the DRAM light for a millisecond, then goes back to the CPU lilght. It seems it's checking and can't move forward.

The Diagnostic LED's seem to say the problem is your ram. If it "flashes the DRAM light for a millisecond, then goes back to the CPU lilght" then the motherboard boot sequence stops at the ram. Check the ram sticks are pushed all the way down in their sockets. You can also try booting with 1 stick.

Thanks I will try, unfortunately I only have 1 8 gig stick.

Have you tried moving your 1 stick of ram to each of the 4 ram slots? Just as an experiment you could try installing you graphics card to the 2nd PCIe x16 slot and see if that will boot.

I reset the CMOS . I moved the GPU and the DRAM stick to different slots. Still same. Wish I could send you a video

What GPU were you using before the new video card? Can you use it again for testing, just to get the computer working?

It was the radion 4850. I did try that change as well. I did buy a whole new case and was going to put everything it the new case. So, I will be rebulding it for the next few days, and will let you know what happens. When I was taking it apart last night I also looked for burn marks on the MOBO, but could not see anything. In the meantime, I will order a new DRAM.

I rebuilt the computer and still same issue. I purchased more ram so I will check if it's the original memory.
In the end I even took out all the hardrives, and had the same issue. Something is stopping it somewhere to not let keep booting and staying in this mini cycle.
