Hello this is my first post and I am a complete idiot when it comes to computers. I have inherited a emachine t 1840 and was not able to use some software programs because the monitors resolution was so low. And in my blissful ignorance I purchased a new shiny lcd monitor the problem is I can't increase the resolution. My second problem is I can't get any sound out of my speakers period. I am using windows xp. I tried to find updates for drivers with no success. My question is would a new sound and video card fix my problem? How do I determine which cards are compatible with my computer? I have already started windows in safe mode and deleted drivers for video and sound. When I restart a found new hardware icon appears but is unable to find drivers with wizard. I do not have backup disk for video or sound. Thanks in advance for any replies.
