Sorry a bit of a long one but details matter, right?
So just before Christmas my PC began to randomly turn off.
Initially it was days between power offs to once a day to more regularly.
My pc was fairly power hungry and overclocked as far as I could go within reason.
3930k @ 4.4ghz
gtx780 @ 1200mhz
Corsair AX760i PSU
Custom loop watercooled for the last 6 months or so
Once the shutting down begun more often I lowered my clocks back to almost stock to see if that helped.
Came home from work one day, turned pc on and it turned off just after getting into windows.
Turned on again and the same thing but a little faster this time.
Then the pc seemed to get caught in some reboot loop where it would turn off seconds after being turned on, turn itself back on again and loop like that without ever reaching windows.
Eventually I just got no power to the pc.
Thinking PSU had died I contacted Corsair as it's still under warranty and they gave me a few things to try.
PSU self test, worked! Jumping the pins on the motherboard power cable allowed me to turn the PSU on!
After seeing the PSU was working from what I could tell I plugged the pc back together again and it booted, except the CPU LED stayed on.
Managed to borrow another PSU a few days later and same result, CPU LED stayed on and PC wouldn't post.
Being Christmas and that my PC was 6 years old and I couldn't source replacement parts to test I decided to rebuild.
Went for a Ryzen 2700x, ROG Crosshair 7 and 16bg of vengeance RAM and thought that'll do.
Setup new machine and it won't boot. Motherboard LED's reporting an issue with my GPU (back in original air cooler).
Found a GTX1060 locally and it works.
So today I received a cheapo Xeon that I grabbed off trademe, it works in my old motherboard. So looks like my 3930k is dead.
Weirdly I managed to get the GTX780 to post on my old motherboard but new motherboard still reports a GPU issue with the GPU LED.
I'm sending my PSU back anyway as the fan is clicking and that's enough for them to take it back under RMA but should I be asking Corsair more questions?
Can I test the PSU in anyway to see if it's faulty to a degree that it killed my old system.
Loads of text but appreciate anyone's input on this.
