I currently have an early 2008 iMac (intel 2.66 ghz, 4 gig ram). I was planning on upgrading my HD with an SSD to speed up the performance of the computer. While I was backing up my old hard drive, the screen started to show floating dots, and artifacts all over the screen. I thought the HD was failing, and went forward with the new drive. Once the new drive was installed, I had the same issue, and in addition, I could not install the OS. I put the old HD back, and currently am restoring the OS, as per the discussion i had with the Apple tech. During the re-install, I am still having lines and dots (picture below). I am thinking it is the display or the video card. Would anyone have any thoughts? Given the age of the computer, I wouldn't fix it, unless it is something I can do myself cheaply. Thank you for any help you provide.
Got a tip for us?

Yes, it can be, although that dosen't rule out a bad hard drive or data cable. What phase of the boot does it get stuck at?
Bad GPU.
If you have one of the iMacs with removable one, a 10 min trip through the oven may fix.
There are also reflow services.
Or get a replacement. Has to be a Mac one that came in your machine as original or option.
If the GPU is soldered to logic board, it will need a whole new one.
Sort of like a $2,000 car that needs an $1,800 transmission.

It's only a matter of time before the issues appear again. Your iMac is almost 7 years old anyway, it may be time to start looking for a replacement.
