Hi guys. Im working on my buddys dell laptop (e1501). He said it was really slow and the fan wasnt working correctly because it was making a noise. So i ordered and installed a new fan and the sound went away. Now I want to speed up his pc but cant boot into windows. I know its Vista Sp1. I can get to the welcome screen but thats it. I cant even get into Safe mode it just hangs with a black screen and safe mode lettering on the sides. Any ideas? He doesnt even have the OS cd.
