The computer was running very slow, we received the error "Display driver nvlddmkm stopped responding " and it would stop responding. Rebooting several times did not work. I booted in safe mode, deleted the display driver and rebooted. It started up, said it was looking for the driver for the display card it found and hung up. The monitor went to sleep and it has not booted cleanly since. I have a USB optical mouse that does not light up when plugged in now.
XP operating system?
Have you ever defragmented the computer?
Have you updated the video drivers?
A good source for updating your drivers is called Driver detective.If your video card is an nVidia card, then go to their web page and update the drivers and then go to Microsoft and update the DirectX drivers.
This is a know issue and there is know known solution to this. My take on this is heating problem and vista power management.
its a big mess and different things work for different people. My take would be to update the nvidia drivers and hange the power settings in vista. Control Panel> power management> balanced.
For more possible fixes see http://i.nconspicuo.us/2007/03/28/nvidia-nvlddmkm-vista-driver-fix-here-is-the-solution/
same as earlier..
did you overclock anything on the pc?? the cpu or the gpu clocks or the fsb??
try posting with only the keyboard and mouse connected and see what happens..
press F or delete button to access the bios and restore defaults there.
Call up HP and have them walk you through NVram jumper clear on the motherboard.
let me know how this goes.......

Unfortunately, I can no longer boot the PC. I disconnected everything, and it won't even go to a post screen. As I mentioned, the USB mouse isn't even getting power. A quick flash when the PC powers on, then nothing. I disconnected the hard drive to force a non-system disk error, but still nothing. Will not boot at all.
