Hello,
My name is Craig Felkowski.  Recently I have been having trouble with my Sony Vaio PCG-K45 laptop.  My screen sometimes flickers off, I think its the backlight, don't know if it has anything to do with my video card.  Mainly though, my problem is that I want to replace my video card.  I have an ATI Mobility IGP340M/345M, and I am not pleased with its performance.  I want to get a video card with at least 256 MB, but have found that I would need to replace my motherboard.  This is where the problem comes in.  I have looked on so many websites, and just don't know enough about motherboards to replace it myself.  My question is, what motherboard would you suggest for my laptop? Can I just buy anyone and install it in my laptop?
