Hello i have a newer dell computer that was given to me by a friend it worked for a few days and then one day i tried starting it up. it will get to the windows screen where it says "prees f1 for bios" at the bottom but then it goes to a black screen with a blinking bar then restarts itself. its like it never kicks over to the desktop. just keeps reatsrting and restarting....i have had a couple of people look at it and a lot of different answers. if someone can help me with this i would greatly appreciate it. it would save me from having to buy a whole new computer.
