Yup, everything fired right up. Old HD is just fine, it was the video card that was the problem. 2 things are left to do now.
When it starts up, the BIOS is detecting a Floppy drive. I went into the setup and deselected the floppy on startup but it still says it cannot boot it, so I have to press the F1 key to continue.
Last thing is, I now need to wipe the new HD clean of everything I put on it, which was not much. Mostly just taking Windows off of it. How do I go about doing this? I know how to take the programs off, and I did not put any personal info on it, so nothing to much to worry about there, even though I'm pretty sure Best Buy might do a wipe of the HD if I say that I had Windows installed. Or would it just be beneficial to keep it in the long run?
