i have a dell 4550. the hard drive crashed. i took the hard drive out and put it in another cpu and reformated it and reinstalled windows xp, updated it to SP3 and all other updates. put hard drive back in origional cpu and booted into windows get keyboard failure during post, but it still works. installed all drivers for motherboard, chipset, video and such. only drivers not on disk that came with cpu were for lan and audio. rebooted cpu to finish installing drivers and now cpu goes to post, i get a keyboard error still and it asks to select OS. keyboard wont work and when it gets past that cpu shuts down. does it every time i boot into windows. if i unplug ps/2 mouse durring os selection screen and plug it back in, and reboot keyboard gets failure error but will work, select os and it asks to boot normal, safe or last known good config, if i select normal or safe it shuts down. if i go to last known good config it will boot into windows b4 drivers were installed and works fine untill the drivers are installed again and reboot. i know its a hardware problem on the motherboard and when the drivers are installed it crashes windows. how can i tell what driver is causing the problem so i can uninstall it and disable the part of the hardware that is causing the problem? i know it is only a short term fix but i need the cpu untill i can get a new one or replace the motherboard.
any help is greatly appreciated.
thanks in advance
