Can anyone please help me. My daughter has an emachine T3414 with 256mb and 80gb hard drive and XP. She has only added yahoo messenger onto the computer and I added system mechanic 6 to it and use Norton antivirus to try and keep things running smoothly. Lately we cannot get it to boot up, shut down, or use IE or any other program without it hanging up. Sometimes it will lock up for an hour or more. Often control/alt/delete won't even work and the only thing I can do is shut off the power. It will lock up even if I go to start and move the mouse to click on one item there- an item from the start menu will highlight when the mouse runs over it and that item will open (eventually) even though I didn't stop the mouse on it or click on it. The computer is only a year old and has had the board replaced (under warranty) once. I am not a computer whiz but there must be something I can do to fix this. She and I are both frustrated with it but cannot afford to take it in to have it checked let alone buy a new one. Does anyone have any suggestions? We would so greatly appreciate your help. Thank you so much in advance.
