I have got an older Dell ~5 yrs old, and just recently it refuses to load my video driver each time I reboot. Sometimes when i restart after booting up, it will load the driver and boot up normally. Most of the time, it just loads a generic 16 color vga driver. I have a NVIDIA G-Force video card. Can anyone help me out with this problem. I do not really have the money to get a new cpu, but need it for school.
