Troubleshoot Screen flickering black and white dots. What is happening?

[Andrew999]

Briefly explain your current issue(s)

dots still popping up on my screen

Steps taken to resolve, but have been unsuccessful

I checked to see if none of the cords have come lose because it is a desktop.

Do you think I have to buy a new screen? I don't have a lot of money so I hope not. what do you think? Thanks

You can try: other monitor, more connection type with monitor and/or cable, reinstall the video driver, try another PCI express port on motherboard, locate hardware or drivers conflicts, also try to restore the O.S.
Unfortunately you have to go for exclusion by isolating the problem.
