my sister lent me her computer to fix the viruses that i found on it. after she bought a new HDD i tried reinstalling windows xp pro. right when the computer is turned on there is a blinking cursor that is at the top of the scree then jumps down about 3 inches and just blinks. i couldnt get into the bios or anything it just sits there. so i put the windows cd in and it loaded the setup. after it loads all the windows files and says it is restarting windows i get the Blue screen of death. its a dell dimension prolly 3-4 years old. any tips or suggestions would help greatly as i am stumped.
