Hello everyone. First time poster, long time reader. This week-end, my girlfriend's comp wouldn't shut down normally. Windows closes fine but the comp would keep running with a black screen, sometimes all night long. Fans were spinning and it looked like the hard drive was working. I had to force the shutdown. It was booting up fine though, until sunday. Sunday morning, she tries to boot her computer but all we have is a blackscreen. No post, no message, nothing. Fans are spinning normally but it looks like the hdd isn't doing jack. Yesterday, i opened her computer and cleaned the dust (lots of it). Then i unplugged the graphic card, cleaned it up a little, plugged it back and the comp started fine the first time. No problems were found. I thought i found the solution but when she tried to reboot it, the same problem appeared: it wouldn't shut down + black screen. And after i forced the shutdown, the same booting problem reappeared with the usual black screen and nothing going on. I am at loss here. Could it be her hard drive passing away slowly ? I will check later today with another screen to see if i get anything but i don't think the screen is the problem. Any help appreciated and sorry for my english as it is not my primary language. Thanks in advance !
