Hah, I am using the dvi adapter, is that bad?

They can cause problems.

3.) If you are using a silly DVI to VGA adapter... God help me...

what is one supposed to do when they don't own a monitor that supports DVI yet they have a higher end card? Yes, they can cause problems but you can't expect everyone own the best hardware available. Some people have to make due with what they have. I myself ran two DVI to VGA adaptors on my 7600gt with a dual monitor setup simply because i couldn't afford LCD with DVI.

When I hook it up to my tv, the screen on the tv is fine but the screen display on my computer monitor still becomes fuzzy with black/gray lines.

Is that good or bad?

Probably just your monitor then or the connection from your video card to your monitor.
