You're clearly near the minimum of the system requirements, but from what I can see still meet them.
Your system has 1GB RAM from which 384MB are used a VRAM for the Intel GM965 chipset graphics (GMA X3100). I've seen Gray Matter running at system with the GMA X3100 with low resolution an low quality settings. That system had 2GB RAM though. But it might work. What the GMA X3100 does not support as far as I know is full screen antialiasing. So the game may crash because of high quality settings that includes antialiasing.
What you should try is to run the Gray Matter configuration tool (doubleclick at the config.exe in the game folder) and then choose the following settings:
- Full Screen: not checked (the game should run in a window then)
- 1024x768 (depending on you display may even work only in window mode)
- Shadows: NONE
- Mirros: NONE
- Rendering: LOW
- Quality: LOW
To confirm the changes click on "Save and Run Gray Matter".
If it works you can try to choose 1280x800 and check Full Screen.
If you can't choose any settings because already the configuration tool crashes, just post it. That problem can be fixed.
Thanks for the advice.
I followed the instructions and obtained a peculiar result. First, a black screen, then the Application error message:
The instruction at "0x006b64e3" referenced memory at "0x00000000". The memory could not be "read".
Thanks for your help - I shall conceded defeat and find another game to play.
