Hi,
My HyperV Server 2012 began suddenly to boot loop after about 1 month. I have stressed tested RAM and CPU, they seems to be OK. But the computer is very sensitive to boot loop cycle after login, when using HyperV Server 2012, Windows Server 2012, Windows 2012R2 Data Center Eval. When I swap the PSU for a CX-600 then all boot loop issues disappeared.
I have a direct warranty exchange, but the store refuses to take it back because they were unable to reproduce the faulty behaviour of the PSU in spite running stress test on 2 different systems. They use Windows 7 64 bits. They said that it could happen that some PSU has troubles with certain brands of motherboard. So they asked me to bring my Server in for a test.
Question: Is it possible that a PSU behavior could depend on a motherboard or OS, of a combination of both? Because the PSU has no boot loop issues when I ran stress tests under Windows XP.
Motherboard: GA-970A-D3 (rev 3.0) + latest BIOS version FD (Jan 2013)
RAM: 32GB, 2x (8GB x2) Patriot Viper3, Black Mamba, DDR3 16GB , 1866. Each pair is mount in the matching color slot on the motherboard.
CPU: AMD FX-8320 + Cooler Master Hyper 212 EVO
Video: Asus EN210 Silent
Thanks in advance for any help.
Answer: After reproducing the boot loop on my own server, with a fresh install of Windows Server 2012. And make it disappear when changing the PSU Corsair VX550 for another one. We could see in the Windows Event Log: the system EventID 41 Microsoft-Windows-Kernel-Power The tech guy at the store told me this was caused by the automatic correction of the voltage fluctuation in the VX550. Which was then captured by Windows Server 2012, which somehow is sensitive to this kind of event and somehow decide to reboot. We exchanged for another PSU brand and that fixed the issue.
