    I keep seeing these weird multi-color single pixel lines across my windows and my system is crashing alot (rather it becomes completely frozen and non-responsive). I don't know if this is a video card problem, or memory issue, or just something in the system OS.

    It does seem that it happens quite often while running Handbrake. I'm still getting these lines with a fresh OS install, so I'm thinking my original video card is on the way out...

    Will replacing it with actually improve performance?

    Run hardware test off the install disk. As it's a Mac Pro, you can just get a new GPU

    Yes, it's your card. Don't bother with hardware test - symptoms are clear.
    It's going bad or it's overheating. Handbrake is very CPU demanding app, heavy CPU usage = more heat generated.

    What you can do:

    1. clean dust off the card and its heatsink/fan
    2. change card's cooler to this: http://forums.macrumors.com/showthread.php?t=319267&highlight= - if card is not damaged it will help,
    3. don't bother with 1&2 and get new graphics card ;)

    Correct. After a fresh OS install, it has to be the graphics card.

    no hardware errors found

    Also noticed that my Hard Drive tests all indicate Temperature Changes towards the fail side. Should I be worried that my system is running too hot?

    I had the same problem. It was the graphic card. I turned up the fans using SMC Fan Control and that helped keep it alive, but it eventually completely died down the road.

    Agreed 100%.

    I have a Mac Pro 1,1 and had the same exact issues. First I adjusted the fan settings, which helped, and eventually I replaced my X1900.

    I seem to remember the x1900 having this problem due to dust and such building up reducing cooling. (NOTE: I am not sure if this was just the Apple released ones, or if the 3rd party ones also had issues. I would assume they would if they were following the same OEM heat spreader / fan layout and such)
