Datis,

Are you using the latest drivers for your current graphics card? If not, it would be highly recommended to navigate to ATI's website and download the latest update.

Also, Microsoft does have an official Windows 7 Support Forum located here http://tinyurl.com/9fhdl5 . It is supported by product specialists as well as engineers and support teams. You may want to also check the threads available there for additional assistance and feedback.

Unfortunately this is a common problem now, it might be solved over time with Windows 7 service pack 1 or 2 ! .

...............................................................................................................
1. Run windows update (check for driver updates under ’Optional updates are available’)

2. Check your games manufactures website for update patches.

3. Try Windows 7 Compatibility, is a mode in Windows that lets you run programs written for earlier versions of Windows.

To start this program

Click on Start icon

In the search section type: compatibility

Then double click on it

Once program opens up, click Advanced

then untick ‘Apply repairs automatically’

click Next

Select your game/program in the list
(if your game/program not on the list, select ‘Not listed’ and browse for it)

click next

next again

then you can click on

Try recommended setting

Or

Troubleshoot program

Maybe there is a problem with the temperatures of the CPU or GPU.
Check that.

XP Mode does not support 3D graphics APIs such as DirectX so it's useless for games.

VMWare supports hardware acceleration, VirtualPC does not, therefore your statement of VM's do not support hardware acceleration is incorrect.

XP mode uses VirtualPC thus can't support hardware acceleration.

yes its the problem ! the temperature of gpu in idle mode is about 80 degrees !
tried to manually set the fan speed to higher values and then no crash !
im thinking if there is other solution for this high temperature !

Good to hear the cause of the system crashing was the fan.

Sorry for the misunerstanding the later part of my previous reply was for Immolatus

If your card is over heating contact the GPU manufacture for repairs or replacment. I hope is still under warranty. (Remember some manfacture offer 3 years warranty on their GPU card).

Keep a distance between the back of your computer case and the wall, you need easy flow of air in/out of the system else it will over heat. Also you should have one fan in front of the case and one at the back.
