When I turn on my Computer, the screen turns black?

Every time I turn my computer on the screen just turns different colors?

  • Right when my computer turns on, the screen begins to change different colors. Green to red to yellow to white then it repeats. I have trid Ctrl-Alt-Delete and taking the battery out but nothing happens. I have a HP laptop, I'm wondering if it could be a virus. Any ideas?

  • Answer:

    You could try shutting it down and when you start it up press F8 repeatedly until you get a screen with the option to boot to the Last Known Good Configuration. Try this first and see if it makes a difference. To get a good accurate answer give the brand, model number, installed operating system of the laptop when asking a question as all PC's are not the same. Hey, I enjoyed your question, I am a retired computer technician. I hope I have helped you... Source(s): CompTIA A+ Certified Computer Professional
