Can you give us a little more information such as what version XP you are using? what happened just prior to your problem?have you installed any new hardware/software? Do you have anti virus installed?
YES. I CAN NOT ACCESS MY CONTROL PANEL, MY COMPUTER, MY DOCUMENTS,USE THE COMPUTER SEARCH TO SEARCH FOR MUSIC OR FILES, ETC, BECAUSE WHEN I CLICK ON ONE OF THESE FROM THE START UP MENU IT WILL CLEAR MY DESKTOP OF ICONS AND STAY BLANK FOR ABOUT 10 SECONDS AS IF IT WERE LOCATING WHAT I HAD SELECTED.
