Issue summary:
PC won't power on at all. No OS, no beeps, no fans, nothing. The physical power button on the motherboard itself is flashing/flickering at a high rate (like on/off 5-10 times a second) orange. Normally it is solid orange when the computer is off and I believe solid green when on. I've had this happen twice before and literally nothing fixed it other than waiting 24-48 hours. This time it happened during a storm so could be surge related.
Specs:
Motherboard: Gigabyte GA-Z77X-UD3H
CPU: Intel I7-2600k
GPUs: 2x Nvidia GTX 670s in SLI
RAM: 4x 4GB of whatever. It has been a while.
PSU: Seasonic X750 Gold
Debug steps:
I tried removing the GPUs and unplugging everything except the motherboard power supplies but the exact same thing happens (flashing power button). I didn't see anything on the motherboard manual about that error signature http://download.gigabyte.eu/FileList/Manual/mb_manual_ga-z77x-ud3h_e.pdf . I tried other outlets, I tried reseating all the power connections... Nothing changes the problem. I didn't remove the CPU because it is a pain in the ass and I don't see how it could help but I did remove its power and tried that.
Summary
So I'm guessing this is a damaged power supply but I haven't seen the flashing power button before so I'm open to other suggestions. This build is ~4 years old now so it wouldn't shock me if the PSU died but Seasonic PSUs really should last longer than 4 years. Anyone have any ideas? What is odd to me is that it recovers after ~24-48 hours without me actually doing anything.
