After a clean WinXP SP2 reinstall the Dell DImension 5150 is booting up/down VERY slow (4-5 minutes) BUT runs fine once booted !
** This slow boot up/down does no arise until AFTER a video driver is installed. This sympton prevails after I do a 'device uninstall' on the video device.
I did 2nd clean WinXP reinstall and installed a PCI-X add in video card. Again boot up/down speed is fine until I install the drivers for this card. After driver install I get the same slow boot up/down same results ! ... Again, once the bootup process is complete system runs fine.
