a Few weeks ago my cousin used a CD with windows 7 on my laptop (windows vista)
now I can't see anything on my screen, when I turn it on it shows me a blackscreen.
It worked for like 5min, after I started Internet Explorer it turned into black.
I restarted my laptop many times but I still see a black screen.
Anyone can help me solve this problem?
Shut the computer down unplug it take out the battery pack. while the pack is out hold the power button for thirty seconds. I put the battery back in plug it to the ac adapter and unbelievably it will come back to life
So you can hear the login sound! That new data for me. It could be hardware problem.
If after you boot and hear the sound, if you flash a light, let's say on the far right side of your screen, try to look from the opposite side at a sharp angle. Can you see a glimps of your desktop? (Move around a little, the light also)
