Please help me, I can't get my computer to start! Yesterday I was watching a video online and all of a sudden it stopped and my computer frose. My mouse still moved but I couldn't click on anything so I held down the power button to turn it off. I have a dell xps with windows vista on it. Now when I try to start it, it acts like its going to start then comes up with the screen that asks to launch startup repair or start windows normally. I've tried both but neither work. Start normally gives me the screen with the bar going across but it just does that forever cause I had it running all night and it still wouldn't start and the repair choice just gives me a black screen forever or gives me a black screen with the cursor. Can someone please help me. Thanks!
