Has anyone seen this after start up?

Almost immediately after startup, my Mac goes to these large black checkered diagonal lines. I’ve run diagnostics and nothing was found. I’ve already had the video card replaced in the past, so I don’t know what this is. Does anyone know? Thank you

Sadly, your GPU’s V-RAM has a problem!

Lets give this a try restart your system and the T key to see if you can get into Target Disk Mode if you can you might see the FireWire icon on the screen. It might take a few times to get it to show up also try resetting the PRAM as well.

I used Target Disk Mode and was able to access the files I needed! I think the computer may be toast though. It’s been around the block for some time, but at least I can still access the old files if I need to. Thanks, Dan!

@brandon3113 - Did you see the icon on the screen? If you did you might still have a way to use this system using the intergraded graphics engine in the CPU.

Dan, I did see the icon on the screen, so it worked out. Thanks again for your help!
