Have you tried downloading and installing the latest driver for the video card?
A CNET review of that system shows it having an ATI video card, you can download the drivers from ATI's web site here,
But double check your system as it may differ and make sure the appropriate drivers for your system.
You can check what video card you have by going to the control panel, click on system, then click on Device Manager on the left menu. When the Device Manager window opens, click the plus sign next to "Display Adapter" to expand it. That will list your video card e.g. ATI Radeon HD 2400.
hope this helps!!
1- On start up screen flashes approximately 3 times while user icons are being displayed. When entering passwords the same thing? Happens to all users (4) on our computer. This did not happen when we first bought the comuter but started about a week later.
2- While working on the computer the screen goes black and the computer stops working, freezes? No response from any key. I hold in the on/off button until computer shuts down. Then I restart. What is wrong?
3- I am not computer literate so please be explicit in your replies.
