Mac Pro First Generation Troubleshooting

My programs take an extremely long time to load or crash constantly.

Replace the RAM modules or add more sticks of RAM. Newer programs utilize more system memory and since this is an older machine the stock RAM might not be adequate.

The Mac Pro turns on, but I don't see the home screen.

Not much can be done for a damaged hard drive. If desperate take it to an expert, if not consider replacing the hard drive or getting an SSD which would drastically improve performance.

I'm seeing dots, lines, discoloration, or broken images on the screen. Or nothing at all

The graphics card is what produces the image on the screen. If you can't see anything on the screen the graphics card is likely the cause. Consider an upgrade for better performance in all programs, especially games.

When attempting to access my Mac Pro, I cannot pull out the HDD drive bays/they open a little bit but then jam up

There are screws meant to hold your hard drives and the PSU/components above them. Ensure all are installed in their proper place and that none are jammed up.

Near the I/O port of your Mac's logic board, there's a small lock for the door and HDD rails. Ensure it's in the unlocked position (slanted at around 45˚), otherwise you run the risk of either breaking the locking mechanism or a bad connection to the HDDs.

I try to open my disk drive, but it won't open.

Remove the optical drive and carefully open it, remove the disk, close it, and re-install in the Mac Pro.
