My computer runs correctly with respect to hardware and Windows and all other programs found in the PROGRAMS & FEATURES within the CONROL PANEL. There are no graphic card nor monitor issues at this level.

However, I am trying to run the game SILENT HUNTER IV (WOLVES OF THE PACIFIC). Silent Hunter is a legacy to XP and it ran without problems under XP. It used to run successfully on this Windows 7 system but now will not. It seems to me that the program developed the following problems after an automatic update driver to Nvidia within the last 6 months but I am not really sure if my memory is accurate for this.

Actually, the game loads and presents the menu for game play. The game starts but only lasts a few minutes before the symptom shows up. It is about this time (it varies) the display goes black accompanied by a loud hum out of the CPU followed by a message on the display stating: "Monitor going to sleep". This unwanted shut down of the display can take place during the game but usually happens within a minute or two of actual game-play. After that there is no way to control the computer. Neither keyboard nor mouse will work and the only way to gain control is to shut down the CPU with the On/Off button to force a manual start.


Upon the assumption that the game is installed correctly, I have looked elsewhere for the problem. The game is placed in the main directory under Silent Hunter IV (C:\Silent Hunter IV). I chose this placement upon recommendation of notes found in the SUBSIM page.

Upon the belief that the display system is not operating correctly, I checked the display driver and it is up to date. The Monitor is an HP 2009m Model #: p6115y. The Driver File Details shows two entries:

C:\Windows\system32\DRIVERS\monitor.sys (highlighted) File version: 1.7600.16385 (win7_rtm.090713-1255)


The graphics card is a NVIDIA GeForce GT 440 updated with 296.10-desktop-win7-winvista-64bit-english-whql driver.

I have the computer set for performance over appearance. I have set the compatibility for SH4 executive file for compatibility to XP. I have done likewise for the SH4 GUI executive file.

The page file is set "System Managed Size".

Device Manager shows no problems.

Power Options for the computer is set at NEVER with respect to sleep mode for CPU & DISPLAY

I sure could use some advice on this one.
