Need help!!

Here's the story, built a PC and it worked just fine for about 2 years then I moved and didn't use or plug in my PC for a few months went to use it again and had an issue where it would power on but no HDMI signal or peripheral power, rebuilt the PC a few times and finally got the PC to work again, now I  left my PC powered off for about 3 weeks and went to use it again and same issue as before no HDMI signal or peripheral power, I have a i7 9700 running on a MSI z390 gaming edge mb with a 1060 6gb. This time there is a CPU light on the ez debug 

 

My issue is I've tried rebuilding and reseating everything including the CPU, have tried starting the PC with one stick of ram nothing happened, tried jumping the jbat pins for 10-15 seconds multiple times while power is unplugged and again nothing, tried removing the CMOS battery for an hour and again nothing. 

 

 

I'm at a loss here i have a spare PC but it's AMD so I can't use those parts to test components, short of paying geek squad or something to do a diagnostic which I'm reluctant to do because they overcharge I have no clue what else to do. 

 

I bought some jumper caps which will hopefully arrive next week but as shorting the jbat with a screwdriver didn't work I doubt the jumper caps will do anything

 

Is there anything I can do to diagnose further or anything I'm missing to resolve the issue or am I just out of luck without taking it somewhere to figure out if the PSU or CPU are in need of replacement.

 

If there's any additional information you need just ask, would really appreciate some insight on this as I have no clue what else to try

You don't need to remove the CMOS battery for an hour, simply unplug the computer from wall power and flip the PSU switch to off. Remove the CMOS battery and push your power button a few times or hold it for 30 seconds. That should remove any residual power in the system and clear the CMOS. Put the battery back in and plug the computer back in. Power it on and voila the CMOS was reset in less than a minute. 

 

If you want to test if it's the power supply the PSU you have in the AMD system should be compatible with the intel as well so you can test that PSU with your intel system to double check that.

 

As for other troubleshooting steps. I doubt it's a power supply issue as the computer is still powering on and showing a CPU debug LED, usually that's related to CPU or Ram, I would try booting up the system with only one stick of ram and alternate it through each slot on the board, see if it will work like that. If there is no change with that, if possible trying a new or separate stick of ram wouldn't be a bad idea, if your other system is AM4 or newer it should have DDR4 ram which should work in the intel system as well. If none of the ram tests fix it being able to post/display next step would be to test the CPU/motherboard.

 

When this system isn't used is it stored somewhere or is it just hooked up and not on?

Hi thanks for the reply I originally tried the PSU off and just take out the battery and press the power button ect. That had no effect even shorting the jbat to reset the CMOS doesn't seem to have worked either..

I also tried the ram check and nothing. As for the PSU I have yet to check with the other PSU as I wasn't aware that would do anything to help but I will try shortly. 

 

When the PC is stored it is just plugged in and off as I mentioned before I never had this issue until moving house then the PC was stored without the power cable in a storage room but again I was able to resolve the same issue by rebuilding the PC and swapping the pcie for the GPU which for some reason seemed to work I had not noticed the ez debug CPU light though when I fixed it the first time..

 

The PC worked a few weeks ago and I just assumed it was stuck in standby as it had been off for a few weeks but nothing I have tried has worked I wouldn't think the CPU or motherboard would just all of a sudden break after working just simply by not being on for a few weeks but that seems to be the case 

As for the other system it's a ryzen 3 and I believe it's ddr3 ram as well so I don't believe it's supported by my MSI board 

 

I'm really at a loss here as no reset seems to work and to have to replace the CPU or MB after only having had the PC for barely 3 years would be a real disappointment, I'm hoping it's just a bios issue but again tired everything suggested and still no fix

Update: I tried the suggested fixes 

I did have a ddr4 in the other system and unfortunately that did not resolve the issue, I also tried swapping the PSU again that did not resolve the issue. 

So I think somehow my motherboard or my CPU has had an issue while the system was off for those 3 weeks and one of them is broken as that seems to be all I'm left with at this point, when my jumper cap comes I will try one more time to completely rebuild the system and if that does not work I guess I'm left with no choice but to take it into a shop to find out if I need to replace the CPU or MB or both at that point I may just wait until I have the money to build a new system entirely.

 

I guess it just one of those unlucky moments in life where the PC breaks after not even 3 years of being built 

 

Thanks for all the help anyways
