i havent turned on my pc in weeks. today i turn it on, sounded normal but i look at the screen and it is still black. So check the connections... all the lights are on... i unplug the video connector and look for picture on the screen which says..."video unplugged ?"... so I plug it back in and still no picture. The computer seems to boot up for about 15 secs and then nothing... no more red light...still running nothing happens. no msgs on screen...nothing. The usuallt boot up time is about 30-45 secs. So is it Hard drive or Video Card or neither.
