Hey everyone--first post in here. About a month ago, I updated my iTunes software and had some significant issues with my laptop. The screen went crazy, eventually resulting in a BSOD, and was reluctant to turn back on. After waiting some time, it finally turned on, but does not respond in any way to touchpad, touchstick, or built-in mouse button input. From the symptoms, I am led to believe that it is not a hardware issue, but a driver issue. I have tried in vain for some time to locate the correct driver to get the touchpad etc. to work on my Windows 7 Ultimate 32-bit. I believe I have the D820 'EP' edition, with the NVidia Quadro NVS 120M 512MB video card, 2GB RAM, and the 2.33GHz T7600 dual-core processor, if that matters. When the touchpad and such did work, it appeared as "Alps Touchpad Device" or something similar. iTunes, however, works wonderfully. Can anyone help me?
