Hi forum,
Shortly after resolving the previous post I'd made about Nvidia driver issues, I began to experience the very odd issue of windows randomly going to sleep. Such behavior includes:
System goes to sleep anywhere from as soon as the windows boot screen is cleared to a couple minutes after bootup (even on a fresh, unmodified install)
When system wakes up, sometimes it's fine, sometimes it no longer outputs a display, and sometimes the system freezes
Issue does not happen in safe mode
Having tried to diagnose the issue for about 2-3 weeks now, I have tried the following (all of which has failed to resolve the issue):
Reinstalling with ACPI disabled
Reinstalling with ACPI enabled
Replacing GPU thermal pads & thermal paste
Replacing CPU thermal paste
Removing all PCI cards, as well as removing only one at a time
Unplugging all non-essential power draws (fans, external drives)
Disabling power management (APM) in BIOS
Enabling only S1 or S3 sleep one at a time
Switching memory configuration and # of sticks (i.e. testing system with only one stick of memory in, switching memory slots occupied)
Disabling all devices in BIOS other than hard drive and AGP slot
Uninstalling and reinstalling "System" drivers
Disabling sleep in Power Management
Disabling ACPI devices in device manager one at a time (ACPI Sleep Button, etc.)
Performing step-by-step configuration bootup, disabling all drivers and features not essential to startup
Installing official chipset drivers known to work with 9x
Other than safe mode, this is the one step-by-step configuration that always resolves the sleep issue:
Process the system registry? [Y]
Create a startup log file (BOOTLOG.TXT)? [Y]
Process your startup device drivers (CONFIG.SYS)? [Y]
DEVICE=C:\WINDOWS\HIMEN.SYS ? [Y]
DEVICE=C:\WINDOWS\DBLBUFF.SYS ? [Y]
DEVICEHIGH=C:\WINDOWS\IFSHLP.SYS ? [Y]
Load the Windows graphical user inferface? [Y]
Load all Windows drivers? [N]
Interestingly enough, I had a similar issue of the system randomly sleeping on my Windows 2000 install (an install on a separate SATA drive). After wiping the drive and a clean install (with no bios settings changed), it no longer experiences the sleep issue. On this working install, I have ran PCMark04 and 3DMark03 to see if the sleep issue is thermal related, but GPU-Z and HWMonitor returned normal values, as in there were no high temperature readings that would suggest Windows 98 is sleeping due to heat issues. I have even run the same version of HWMonitor on 98, and it also did not return high thermal readings.
I would like to note that this issue began after installing the drivers to my ethernet card and removing a wireless network card who's drivers never loaded correctly. But correlation does not equal causation.......
If anyone could offer any advice, I would greatly appreciate it. Fixing this issue has taking up more or less my entire free time these last couple of weeks. I also have limited disposable income, so I don't have the flexibility to just buy new components and see if the issue goes away.
