PC won't start

[sl0011]

I was moving my entire desk with my computer and monitor over it and suddenly the screen and peripherals turned off. Fans kept spinning. 

 

I have seen this kind of behavior before, it indicates that the CPU is not working properly or the connection between the mobo and the CPU is having issues. I say this because the CPU light on the mobo is on. 

 

My theory is that some cable got disconnected while I was moving the desk. 

 

I have taken the entire mobo of the case and connected everything again with no success. Put the CPU out and in. Only one stick of memory. 

 

Right now I am waiting a few minutes with the cmos battery out. This is kind of frustrating since it was working perfectly. 

 

The CPU is a 5600 on a B450 motherboard. PSU is NZXT C750 gold.

 

Any tips? 

 

Update: CMOS battery out for 15 minutes and still nothing. Here is a quick video.

You need to reseat the cpu. So remove your cooler and cpu and check if there's any bend pins. If there's none, then put back, with a new paste(if possible). You can also reseat the rams as well.

The EZ Debug CPU light is on, indicating it is an issue with the CPU.

 

As stated, Reseat CPU and check for bent pins or burnt marks.

CPU pins look fine to me. No signs of burn or anything. I have already reseated it. I guess I'll just go part by part cleaning and connecting again very carefully. 

 

There were some minor residues of thermal paste, maybe that's it.

It works! I don't know exactly what it was, but I unplugged everything, cleaned all the thermal paste, blew all the dust off the motherboard, and it started working again.

Glad you got it sorted
