Compaq Presario SR1500NX Windows 7 Video Driver
I was recently installing Windows 7 on a Compaq Presario SR1500NX PC. Finding the proper video driver was quite a chore. There are no official drivers available, so I used the Windows XP driver installation which successfully installed the VIA/S3G UniChrome IGP video driver. You may follow these steps to accomplish the task.
- Visit the website of the video chip maker at www.via.com.tw/en/support/drivers.jsp and select "Windows" for the Operating System Type, "Windows XP" for the Operating System, "Integrated Graphics" for the Type of Driver, and "KN400 & KM400 UniChrome" for the Via Product.
- You will then be taken to the download page. Select Download version 16942416. To make things more simple, you may click on the link listed here directly and skip step 1, but if they have changed the link and it is broken you must follow the steps listed. This downloads a Zip file with the driver setup program.
- After extracting the drivers from the ZIP file, go to the folder where the drivers are located. Find the file called "Setup", right click on the program and selected properties. Select the "Compatibility tab, and check the box labeled "Run this program in compatibility mode for" and leave "Windows XP (Service Pack 3)" as the selection. Select OK.
- Double click the Setup program and run it. When you are done, it will request that you reboot. Do this and your video drivers will be installed.
- Upon rebooting, you will receive a Windows security alert asking if you wish to run a program called VTTimer. You can cancel this every time you reboot or proceed to step 6 to remove it from the startup process, since it is unnecessary.
- Select Start and type "msconfig" in the "search for program files" box and press enter. In the MSConfig program, select the Startup tab and look for the startup item that has the command "VTTimer.exe". If you have just loaded Windows, there should be only 2 items and this is one of them. Uncheck the box on that item and select OK. You will be asked if you want to restart. After restarting, Windows may bring up a message reminding you that you turned off a startup item. You can check the box that tells it to not remind you again and select OK.
Because the Via KM400 chipset is older, Windows 7 will run in Aero Basic mode instead of running Aero Glass. With these drivers, you can extend the screen resolution to 1280x1024. When viewing videos such as those on YouTube, I found them to be a bit choppy in both regular and full screen modes. I also found DVDs would not play with the standard Windows 7 Media Player - it kept giving an error about needing to lower the screen resolution. I presume it just didn't like the video chipset or drivers.
