CPU or Motherboard Dead ?

bonewood · 18 Oct 2020 at 20:15

Hi all looking for some help and advise if I can. I moved house yesterday and before the move thr PC was running fine, got to the new address and set the PC up booted up fine then 5 minutes later just black screened with no signal.

The problem I am having is I power on motherboard lights up all fans start but no signal to the monitor, I am getting no error codes from the motherboard

My system is
MSI X99A Krait Edition
5820K
16GB Ram
EVGA 1070

At the moment I am thinking motherboard or CPU as it is the only 2 components I haven't tested and cannot test

So far I have tried
Swapping in brand new gfx card
Swapping out the ram
Changing display port cables
Taken out Cmos battery
Selected other on board bios
Cleared Cmos
Made sure Cpu is in properly

Really don't know what else to try so thought I would come here for some help any thoughts would be greatly appreciated

Why couldn't it have happened in 3 weeks as I plan on upgrading when the new ryzen hit the shelves

Thanks in advance

Something come loose and got lodged behind the mobo and case causing a short? Sometimes a rouge screw you lost 4 years ago turns up when moving house. I would strip back including take out mobo and inspect the back of the board for any signs of shorts or cracks then rebuild it back up and see if it works.

All the board and caps etc look ok nothing look burned look at solder joints too. Did you try GPU in a different pci-e slot and not just the same one as before you moved it

I'd test the most basic setup I could get away with, entirely outside of the system sat on a box or similar.

Board, CPU, one RAM module, no SSD's, no mice or keyboards, nothing other than the PSU to power it all. Then try the GPU in different slots as well, and also check your monitor is not the fault by plugging a DVD/player or games console into it.

Do you have a DVM to check the voltages coming from the PSU to the EPS/PCI-E and 24-pin?

Monitor is good PS4 running fine on it as for the other stuff you mentioned not gone that far with it but will give it a go
