[SOLVED] PC won't power up - - - - potential short circuit of motherboard ?

[Shalou]

Hi, everyone. Yesterday I tried putting my usb 3 header into the motherboard and realized that it's a faulty cable with 2 pin holes clogged. Because of this the IntA_P1_SSRX- and Vbus touched each other for a while. I turned on my PC without realizing that and it turned on for 3 seconds then it shut down. Now I can't power up the PC by any means. The power led on the motherboard is blinking once every 3 seconds.

PC Specs
Motherboard: ASUS H87 Plus
CPU: Xeon E3-1245 v3
GPU: RX 470
RAM: 28GB
Storage: 6 x SATA drives.

Is it possible that I accidently killed the entire motherboard and even the other components?

Things that I've tried so far:
1. Use another PSU.
2. Plug everything out from the motherboard.
3. Same as 2 but keeping the CPU.
4. Breaking off the pin that potentially caused the short on the usb 3 header.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

1. Use another PSU.
You sure you didn't source a poorly built PSU as well?

That would've caused a (5V)short to ground...and if so, you're looking at buying a new motherboard.

CPU: Xeon E3 1245 v3
CPU Cooler: Cooler Master Hyper 212 EVO
Motherboard: ASUS H87 Plus BIOS was the latest version.
RAM: It's a mixture of DDR3 RAMs. 2 of them are Kingston low profile 1600 MHz 8 GB, one of them is Corsair 1600 MHz 8 GB, the other one is a random 4 GB 1333 MHz RAM.
SSD/HDD: Kingspec P3 256 GB, Netac N530S 250 GB, Samsung 870 EVO 500 GB, Seagate 2.5 500 GB HDD.
GPU: Powercolor Red Devil RX 470
PSU: Gigabyte P650SS Ice, I bought it a few weeks ago.
Chassis: A no-name ATX chassis I got from facebook marketplace for 5 bucks.
OS: Windows 10 Pro version.
Monitor: MSI MP252L

I used my old chinese PSU that ran this system for about 5 years without a problem. I'm assuming it is not the PSU but a fried motherboard because of the shorting. Would it be possible to fix the motherboard?

Edit: Is it possible that this short circuit could also damage other components? Or is it very highly unlikely?

Disconnect everything from the motherboard except one memory and CPU and see if you can get into BIOS without issue.


EDIT: I read the previous posts fully... sounds like you fried the MB and need a new one

Still power led blinking once every 3 seconds :c

Do you have warranty on the MB? Have you reached out to ASUS to see if they can service it?

I doubt it, this thing is like 10 or more years old.

Yeah... I think it's a good excuse for me to get on AM4 right now. Thank you everyone for the explanation and the informations!!
