Hi Sebastian,

This is cody, one of the original creators of this guide. From what you describe it could be generalized to a bunch of different things but in many cases if the lines are horizontal it will be GPU related and if they are vertical it will be LCD screen related. Although you didn't specify which way the lines are going I can give a general solution for both. For vertical lines, the best solution is to replace the screen, which we have a guide here on how to do, but those can be expensive to do so I would suggest using an external monitor such as a TV or maybe one you find used from somewhere locally near you and just us it as a normal desktop PC. Just make sure your external monitor and computer both have HDMI ports to connect them to.

If the lines are horizontal then the cause might be due to the GPU drivers being corrupted or outdated. This will require you to uninstall the current drivers and find the new updated ones from the GPU manufacturer's website. Just be careful of fake websites.

Hi ma7ame7oo,

I'm cody and helped in the original making of this guide. To answer your question what you're looking for is compatibility. What I mean by that is Dell only made (from my knowledge) two different motherboards for this computer that would be compatible for it. That would be the inspiron GPU and the AMD GPU. There is always a possibility of being creative enough to find a motherboard to fit the computer, but that task is a little out of the ball park for the average person. So to answer your question I don't believe it would be possible to find a new motherboard with an I7 that would fit this specific computer and just plug and play. I'm sorry I couldn't help more but I hoped I answer you're question.

Hey Daniel,

My names Cody and I was apart of the team that created this guide. To answer your question, sadly we did not take any pictures of the back of the motherboard when we had it disassembled. As for the compatibility for an M.2 drive I did not see a port that would be compatible with it but our computer could have a different motherboard than yours does, which means there is always a possibility that yours does have a slot for one. The only way to know is to take off the bottom cover of your computer and you would be able to see an existing M.2 in your motherboard or an empty slot for one.

Thank you for leaving a comment, I hope this helped you out.

Sincerely,

Cody Charnisky
