I have a Dell Precision m6300 laptop running XP. Since Endppoint Encryption was installed my Nvidia drivers for a Quadro 3600FX adapter fail randomly. Sometimes the driver loads and I get the nvidia icon in the system tray and sometimes the driver fails to load and then in control panel the adapter type is displayed as unrecognised. I have installed the newest driver I can from NVIDIA's website.. and have updated the BIOS on the laptop but still get this intermittent fault. Sometimes a simple reboot will fix it - other times I have to reboot several times before the driver kicks in. Dell have replaced the adapter also!
No BSOD - the laptop works fine. The display driver loads intermittently after MEE was installed. I can remove the driver and reinstall a new one - no problem. Then after a day or so the the laptop will fail to load the driver again. The fault happens randomly. One day its fine - and the next day it's not.
