I had to re-install Windows XP. All went well after what I was told to have was a MBR virus. I reinstalled all the drivers (provided by Dell) except for the Intel Graphics 845 driver. My computer detected the hardware, and when I installled it, completely slowed down my system. It wouldnt even let me in Device Managaer to uninstall it. I went into Safe Mode to uninstall it, did that and when I booted back enter normal mode the driver was still there. I barely could use my mouse for anything. What do you suppose could be the problem? and do I really need it? Should I re-install the OS again and just not reinstall the graphics driver (Display Adapter)?
