I have acquired 3 days ago a new desktop machine, with Intel CPU and motherboard (mb), viz., i7-4770 and DH87MC, respectively. My other hardware is: 1) a Samsung SSD with 256 GB, 2) a Seagate HD with 2 TB, 3) 2 x 8 GB Kingston RAM. My only operating system is a Debian Linux sid (unstable) distribution, which I installed right after the purchase, without enabling the UEFI boot, only the Legacy one.
I am facing the following problem: every time I try to shutdown the machine, either via the KDE main menu icon Shutdown, or via the root command "shutdown -h now", the machine turns off, but then, right after some 2 seconds, reboots, like a zombie! The only way I manage to turn it off definitively is by pulling off the Power button of the case during some seconds...
Is this a bug of the Visual Bios program of the board? Is this known? Some long time ago, I remember having similar problems with another board (don't remember the brand or the final solution). Is there a chance this might be solved by a BIOS upgrade? How should I do it, without Windows, just plain Linux?
Thanks for any directions!
Based on the fact that Linux* is not a supported Operating System for this motherboard, our recommendation is forwarding your inquiry to your Linux* distribution support community for further assistance on your original inquiry.

I honestly couldn't tell you. the first thing I do when a mother board come in is install the latest bios (since "that is the first step in the troubleshooting process." stated on the intel telephone tech support). out of the 70 of so boards I've put together these are the conditions I was able to use to duplicate the issue.
What I could recommend you is to try if installing BIOS version 0152 fixes this behavior?
I triple-boot Debian Sid, Windows 7 Pro and Windows 8 Pro using UEFI, and have the exact same issue not only in Debian but also in Windows 7 and in Windows 8.
I am running the latest BIOS (v. 0047).
I was playing around in the BIOS settings one day and changed Processor Power Efficiency Policy from Performance to Balanced. The issue went away but then, after some time, it returned.
Board: Intel DH87MC
CPU: Intel i4770
PCIe: Sapphire Radeon HD7750 Ultimate
PCI: Chaintech AV-710 sound card
Storage: 1 Intel 520 SSD and 2 Western Digital SATA hard disk drives
Memory: Kingston HyperX 2x8GB
PSU: Cooler Master Silent Pro 600W
I am waiting for a BIOS update that would hopefully fix this. In the mean time, I want to try the system without the two expansion cards (video card and sound car) and also try a newer, Haswell-compatible, PSU, to see if the issue is caused by a conflict with any of them.
