My friend is asking me to help him with his laptop that died during a windows xp installation. It's a Compaq nc6220. The problem is that the system doesn't start consistently. 9 out of 10 times when I power it on, nothing happens, nothing comes up on screen. When the screen does come on, i boot from the cd drive but the windows install never finishes, always hangs up. I used the Ultimate Boot Disk to try and wipe the CMOS and got further in the installation process but still hangs up. Anyone got any idea on how I should approach this system?
