Hi, I'm new to this site, so forgive any faults in this post. Machine had powered itself off at some stage. When it is now powered on, normal activity appears to take place, fans start up, keyboard lights flash, and the hard drive appears to work (can feel vibration) but nothing comes to the screen. Can it be simply that the video card is blown ? or are ther other options I can try before acquiring another video card. (type: Ge Force PCX).
