[SOLVED] After Faulty Powersupply Mobo EZ DEbug LED on CPU

[NickGreez]

Alright, so yesterday I decided to go get myself a new GPU after having a 1060 for 3 years. I went to go put the graphics card in then all of a sudden I smelt burning and immediately unplugged it. I figured out that the PSU was dead so I grabbed a old PSU 600 Watt from a old pc that I had and it seemed perfectly fine everything turned on and no smelling. But there was no post. I looked at my motherboard and there was a light which was from the "EZ debug led" which was over CPU.
Specs:
5500XT (new gpu) 1060 (old)
B360m Bazooka Motherboard
i5 8400
16 gigs ram
I have tried
Resetting the CMOS
Putting Back in the 1060
Putting no GPU in
Re seating the Ram
Unplugging and Repluging all Cpu and Motherboard PSU Cables
Also During the GPU installation nothing was touched near the CPU or its cooler
Is it possible that the current PSU that I have can't power my CPU or do I need a new MOBO or CPU?
Any help would be great thanks!

Also Just curiously I unplugged both of my ram sticks and still the Ez Debug led is still on the same light
Also Re seated the CPU

.....I went to go put the graphics card in then all of a sudden I smelt burning and immediately unplugged it.....

Please say that you didn't try to change out a video board while the PC was powered up.

 

[NickGreez]

No of course not pc was completely unplugged while installing the graphics card

Also I would like to add my CPU fan turns on all my case fans turn on my RGB turns on it has no post and the CPU debug indicator on

Your nose becomes one of your best troubleshooting tools here. Where is the smell of burnt electronics strongest? It's likely that the old power supply did, in fact, fail. However, it's also very possible that when it failed it took out components on the motherboard.

 

[NickGreez]

So currently after putting the new PSU in and everything nothing at all smells and nothing looks burnt. The PC was a pre-built that I have been updating. When I took out the PSU I looked at it and it was from a Chinese company that all text was in Chinese so I wasn't surprised if I'll be honest

Electronic components rarely fail in a manner that leave visible traces, with the exception of electrolytic capacitors. Assuming absolutely nothing else, besides the power supply has changed, then you're looking at a likely motherboard replacement.

Do you think it would be worth it to have someone (a actual professional) look at it at least? Also do you think my CPU is dead because still it seems like a normal start up just minus the actual boot.

If you don't have the expertise yourself then yes, by all means take it to a professional.

 

[NickGreez]

Do you think that my CPU is perfectly fine it is just my mother board?

 

[ex_bubblehead]

Without in depth troubleshooting there is no way to answer. However, in 40+ years I've encountered very, very few failed CPU's.

I guess time for a opinion what do you think of this motherboard. https://pcpartpicker.com/product/Rj...cro-atx-lga1151-motherboard-prime-h310m-e-r20 looks fine to me just need something to get it up and running. Also to make sure the CPU isn't dead should I try to boot up the MOBO with no CPU power to see if it does the same thing? Also could I try to replace the Mobo battery to see if that does anything?

 

[NickGreez]

Also I just want to make sure I'm clear that even though the cpu fan works the pc boots but doesn't post, all fans are on, and by all means looks to be competley normal while booting, but I do need a new motherboard correct?

 

[ex_bubblehead]

If it doesn't POST it doesn't boot. Also, the fans simply work off of either 5V or 12V being present and have no relation to POST or boot. Best guess is motherboard, but none of us can see or touch your system so it's only best guess based upon experience.

 

[NickGreez]

Alright well thank you guys I'm going to go have someone look at it and see what goes on from there. Have a good one.

UPDATE After grabbing a new MOBO everything works completely fine
