Hi all,
I have a workstation with erratic power loss problems. At least I think it's power source or supply related. After rebooting (the system apparently loses power briefly, then starts back up), I usually (always?) have two related events (IDs 6008 and 41) in my system log:
"The previous system shutdown at...on...was unexpected"
and
"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
I see no evidence of a STOP error. There is nothing in C:\Windows\Minidump, no C:\Windows\memory.dmp, and nothing in the event log indicating a STOP error. The system's "System failure" options are configured to "write an event to the system log" and write Kernel memory dumps to "%SystemRoot%\MEMORY.DMP".
It's a fairly basic system, running Windows 7 64-bit. Below are some hardware specs.
PSU: Ultra Lifetime Series Pro (LSP) 450W
MB: Intel DP45SG (with latest firmware)
CPU: Intel Core2 Quad 2.67 GHz
RAM: 8GB (4x2GB) Kingston 9905403-011.A00LF
Video: NVIDIA NVS 310
HDD1: Samsung SP1614C (SMART: healthy)
HDD2: Seagate ST1500DL003-9VT16L (SMART: healthy)
CD/DVD: Pioneer DVR-213NP
I regularly use external devices (UFDs, external drives and drive docks [eSATA and USB], external CD/DVD reader/writer, etc.).
So far, I haven't noticed any consistency with the power failure. It seems to happen any time, and doesn't coincide with any particular software, connecting / disconnecting external hardware, etc.
I suspect the power supply and I'm ordering a replacement. I think the installed power supply should be sufficient in terms of output capacity (450W), but I'm upgrading to a higher-output supply, in-case.
I would appreciate your wisdom on troubleshooting the problem, and / or testing the installed power supply. I'm interested in testing it with a multimeter, and would prefer to not purchase power-supply-specific test equipment. If the problem is power-supply related, I'm guessing it could be difficult to determine this with a multimeter, given the intermittent nature of the problem.
Thank you in advance!
