the 5740 has 2 different variations of video cards used within the system, can you tell us weather your system uses the ATI model or the intel model of the computer? you can find this by going into control pannel, clicking on performance information and tools then at the bottom clicking on "view and print detailed performance and system information" (this will not actually print it unless you tell it to). inside of that window that comes up after clicking on it will be a performance chart and more detailed information about the computer. what you will need to find is "Display adapter type" and tell us what it says.
The display adaptor type is 6.1.7600.16385
