Stubborn problem with Ati-videocard

My Ati Radeon 96000 XT-videocard gives problems. An even time per day, on arbitrary moments, becomes my screen just black and appeared after it the report 'VPU Recover has the graphic versneller again started because these no longer reacts', with the possibility a report to Ati to steer. Sometimes the screen falls totally out. The pc pleases then yet normally, but the monitor is then no longer from the standby-modus to get.

The some that I then can do, is the pc again reboot. The report hangs according to me not together with the programs that I turn. By 3D-spellen lifted the rarely or, and sometimes lifted the just source as it totally no application do never open state. Also the system suddenly spontaneous herstarten can. It appears on it that this self shows since I Service Pack 2 furrow Windows XP have installed, but that know I not certainly. What is there at the hand and how I of these problems come off”
