screen and graphics crashed after pressing test button

[browe]

My system has the latest 7.10 updates applied. Intel quad with intel on board video.
00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 02)
00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 02)
motherboard says its the GMA3100.
I opened screens and graphics. Then set my monitor to a generic 1680x1050 LCD. Pressed ok. It didn't save.
I opened screens and graphics again. Went to the graphics card tab. select Choose driver from list. Select Intel from Manufacturer. Select 965 from model. select ok. It puts the i810 - Intel driver on the list.
Click test - screen goes black - that returns to the desktop and the program has crashed. no messages its just gone.
When I open screen and graphics and check drivers its back to the vesa driver.
