I have a gateway 550 gr with windows xp. recently it would boot up to the point where there is a single wight dot on the screen and i pressed f8 and started it in safe mode and then got it to start normally. Now, i turn it on and it gets stuck on the gateway screen every time not allowing me to even press f8. There is less than 5 free gb on the computer's hard drive which could be the problem. Also I have an external hard drive attached and in the past it has caused problems but i don't want to remove it without using the safely remove hardware button. Any ideas?
