I’m having an odd problem with a system that I collected from a customer a several days ago.
After about 20 seconds from pressing the power button, the system powers itself off. Any subsequent attempts to power the system on result in a problem free boot up and the system runs fine for the rest of the session. The shutdown only happens if the system has been idle for several hours. (Normally over night.)
The system is a self-build with the following spec:
ECS Geforce 6100SM-M mainboard.
Athlon 64 X2 Dual Core CPU 4200+
NVIDIA GeForce 7300 GS (512 MB) display card
2 x 1GB PC3200 RAM
2x DVD-RW (On single IDE cable.)
1x WD 500GB HDD (IDE attached to SATA channel 0 using adaptor.)
I have tried the following (without success) in trying to pinpoint the cause of the shutdown:
Swapped out the PSU, RAM, display card, Hard Drive.
Tried hard drive on SATA channel 1
Attached HDD to system using IDE cable.
Detached optical drives.
Cleared the CMOS
Checked for possible shorts.
Tested all system components with Goldmem, Western digital Datalifeguard and PC Doctor diagnostics utilities. (WD Datalifeguard reports non-repairable faulty sectors but I suspect this is a consequence of rather than the cause of the problem.) Ran Lavasys Everest CPU, RAM, HDD stress tests for 9 hours without issues.
I don’t have a spare AM2 mainboard or CPU to swap these components out.
The case is high spec with front panel display and has a PSU with some proprietary cables leading to the front panel. (I can’t determine the make of case so I’m afraid I can’t give much more info on it.)
Thanks in advance for any help offered.
