CPU power socket burnt

[Wing__]

Yesterday I started a virus scan and took my dog out for a walk. When I came back the computer monitor is not displaying (not sleep mode). I had the issue before but usually can be resolved by simply restarting the computer.

So I tried restarting the computer but the button does not work. I try holding the power button to turn off the computer yet it is not giving me any response either. (tower lights are on for the whole time) So I shut off the power by switching the power core switch in the back.

First I wanted to try out and see if there is something wrong with the monitor (or monitor cable). So I changed different cables and keep turning the computer on and off using the power switch. Yet still no display on monitor.

Later I tried reseating the cables and turn on the computer yet still not working.

Today I took the computer to a PC repair shop, they took off the liquid cooling and found the CPU power socket is burnt. There are burn marks on the mobo as well as the power core. I tried testing my ram on my wife's computer and it is giving me the same issue (no display and tower buttons not working)

I have already ordered new mobo and power supply on amazon (hoping the CPU is still working), but I really want to know what might be the issue that caused the burnt.

I have AMD FX-8350 as CPU and R9 380 4gb(new GPU I have for 3 weeks) for GPU. My power supply is 650W.

Is the CPU power socket already burnt that is the reason why I am having this issue? Or would it be the ram malfunction and the CPU power socket is burnt due to me switching it on and off?

Welcome to Tom's Hardware Forums,
The most common causes of the CPU power header burning would be that it is overloaded or the connection was loose. It may have also been caused by a faulty power supply. How does the connector from the PSU to the CPU look, is it burnt also? What PSU and motherboard were you running? Any overclocks?

I have Cooler Master GX - 650W 80 PLUS Bronze Power Supply (RS650-ACAAD3-US) for PSU
and GIGABYTE GA-970A-D3 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard for MOBO

Both the socket on MOBO and the power core are burnt.

BTW I have just got my new R9 380 GPU wondering if that is the reason the power voltage is not stable?

I am guessing maybe at the first place the socket was fine but RAM is broken. Then I switch the computer on and off too many times that cause the power surge?

What version of the GA-970A-D3 were you using? (there have been 6 revisions of that board)

Here's my suspicion; The PSU was delivering funky power and the motherboard's VRM was working hard trying to compensate. My guess would be that the northbridge suffered which, in turn, damaged the ram and possibly the CPU also - it may have been due to a loose connection (which has an effect on power delivery) or it may have been a fault of the PSU, likely no way to tell at this point.
