Hi everyone, this is my first visit to this forum so please be patient if I don't get it right, my Laptop has XP pro and an ATI Mobility Fire GL 7800 video card. After updating the system to XP SP2 and other updates from the IBM site I now find that I have an intermittent problem with the display. The display will freeze, on some occasions after only a few seconds after bootup or could last for days. I have tried various fixes, uninstalled and reinstalled drivers using the latest from both the ATI site or the IBM site. At present I am using the latest Catalyst driver (last resort)which is compatible with all ATI drivers. Problem is still there though not as bad. The error log shows that the file ati2mtag is causing the problem, I had thought that with changing the driver that this file would be replaced/updated. Any help would be very much appreciated.
