I've taken my computer apart (mainly the video card for dust since that killed my last one, and on occasion the memory sticks...if that's what they're called.) Today when I was done checking everything and putting it back (like I have done several times before), I turned it on and while the fan on the heat sink would turn on, along with the smaller one on the video card), my monitor would say something about VDA/DVI (or something of the sort) hookups/cords. I tried taking it out and putting it back in, unplugging everything (mouse, keyboard, wifi, speakers), letting it try to boot up for a few minutes, but --nothing-- showed up on my monitor beyond the little notice. As far as I know I didnt 'break' any bits off the motherboard. Is this something that may be able to get fixed (and cheap), or do I say screw it and buy a new computer?
