Why Windows hangs at boot logo if you have enabled the PCI video card?
There are two identical system unit hp dx2000m, both are OK, each for 5 PCI slots (not Express, 32-bit, 33 megahertz) and two graphics cards of ZOTAC Gfors 430 (both serviceable).
After installing the drivers, Windows starts to hang during boot. But not every time, but only if the system unit was turned off and then turned on.
Under normal reboots all is loaded normally. To fix the hang you need to go into the BIOS and just resave the settings, it helps to first palgaga off. The batteries are not dead.
Both sistemnik tried WinXP and 7 and flashing the BIOS the Mat Board to the latest. The result is the same — hangs.
