Any resolution to this? I'm running into very similar issues, and trying to figure out if there's a way to fix them, or if there's just a bad batch of Intel motherboards out there.
Similarities to the original post:
- problems booting, occasional three-beep memory errors
- repeated "catastrophic power event" messages
- using a Corsair PSU (AX760i), however, it had been running flawlessly with a Gigabyte z77 motherboard, so I'm skeptical that the PSU is the problem, but perhaps the "power event" issues have something to do with the interplay between the intel board and the Corsair PSU (and the other issues are separate).
Other issues:
- pressing the "back to bios" button cause the power on for a second and the immediately power off
- installing a PCIe card appears to cause the machine to either give a three-beep memory error or a two-beep video error; using the integrated graphics was working (other than the power event messages and occasional memory complaint.)
Any update from Intel on these issue?
