I have a computer running XP Pro, which works fine but freezes about once a day requiring a hard reboot. Given in the past, I have found this to be the video card, I changed the old one to an nVidia GE Force 210.
The motherboard is an Asustek Computer, Inc. Model M2V-TVM (I know -- not the greatest). After installing the card, whether I just ran the DVD or browsed to the driver, it was very difficult to add the driver, which did not allow the monitor driver to install.
After a few tries, I was finally able to install the driver. This immediately allowed the monitor to install. It still did not allow enough pixels, and I noticed that the driver was disabled. The onboard video's driver was disabled. I am not quite sure how I was able to view the monitor, but I could. I then went to the device manager and enabled the driver, and everything was fine.
It continued to freeze requiring a reboot, and it would get to the screen where the lights would move across the screen under the XP Pro logo. They would NEVER make it. They would freeze. A reboot would take me automatically where I would have the choice to select boot to last known good configuration. This worked EVERYTIME. After booting into Windows, the driver would be disabled with a red x on it. I would enable it and everything would be fine.
I am not saying that the video card is causing the freezing. Just now I seem to have two problems. It is connected with analog, but I can connect it with DVI if that would help. I have looked in the BIOS for a place to disable the onboard video, but I can't find it -- if it is there.
