After i installed xp pro sp2 in my pc, i updated the display driver and i got a blank screen afterwards. I rebooted the pc and it wnt straight to the safe mode screen, but it won’t let me select an option. After the countdown it starts loading windows than it turns all back, crashed and restart all over again.I tried to use a boot disk but it won’t read from it. It repeats the cycle over and over again. I can’t access the BIOS either.It frezzes completly in the Safe Mode screen.
