XP sp3 randomly goes into terminal hibernation, even though hibernation is disabled. CPU fan continues to run but monitor reports no vid signal. To restart it is necessary to turn off power to PC and monitor until voltage drops and the light go out on the monitor, then the PC will restart. It may restart and shut down before reaching windows load, or after loading windows. several times (repeat restart procedure each time) Also noticed is intermittent hang problems whileoffloading audio from the Olympus DS-40 recorder.

Best practices for resolving DM1Service issues

A clean and tidy computer is the key requirement for avoiding problems with DM1Service. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
