There's black lines occasionally popping up on my HP Laptop, and it's all glitchy looking.
This happened after it overheated, so I'm assuming I fried the Graphics Card or something.
My HP Laptop is 6 years old and has had frequent bluescreen issues.

I've tried both now, but they seem to do nothing. I changed the 32-bit color to 16-bit color, though, through advanced settings on the screen resolution "page", but that only fixed my desktop. Games of any kind are still an issue (any Steam game, for example) as they're majorly bugged with skittish lines and triangles alike; the whole screen is also distorted while in a game.

 
well, you might try and plug in an external monitor to see if the problem is in the graphics card of the laptop or in the screen of the laptop.
You might also revert or update your graphics driver also. I kind of expect that over heated graphics cards tend to have memory chips that pop their solder connections from the graphics card. The attempts to update the memory but the graphics buffers updates are not passed to the screen because of the bad physical connection from the broken solder joint.

I have also seen the same type of bad connections on the screen cause by the connection from the frame of the screen to the connection on the screen panel. (that is why I suggest connecting to a external monitor or tv to see if you still get graphics corruption)

Also note: older electronics from the 2008 era were starting to go "green" and used new lead free solder, problem is this new solder was very brittle and would crack when exposed to thermal stress. It is one of the reasons many of the manufactures reduced the warranty periods.

 


You most likely fried the graphics card.
 
Could be a lot of things really, with HP it never is easy to pinpoint anything. Probably GPU/Mobo related though. You got an old one, piece of advice from someone who had an HP, avoid any HP product in the future, don't even buy cables from them if you ask me.
