Dell G3 15 screen gets distorted and makes a single squeeck noise

Hi @zarakkhan026 welcome to this user to user discussion forum. This is not Dell Support. 

You want someone from Dell to look into this screen issue. If your system has a current Dell warranty, use your online Dell account to get Dell Support to create a Service Request for you, so that Dell knows that there is a problem to fix. 

You can also click on @DELL-Cares to send Private Message requesting their assistance. 

If this noise and screen distortion happens when moving the lid, its probably a loose screen connection/cable.

Hi there! Did you ever find a solution for this issue? I am experiencing the same issue currently and would appreciate a fix.

hey, so apparently this is related to a hardware thing? I have the same problem, like moving it, and also I have tried to press hard on the keyboard and it glitches, I'll try few things but for now can you try the same thing like put it on a desk and press hard on the keyboard?

I eventually took my device to a repair shop, paid money to them, and the problem still occurred. I wouldn't recommend taking that step, as it seems there are no resources online to fix this issue, so they won't help too much. However, my problem was resolved by taking apart the computer and removing a memory stick that I perceived to be dead. I had a notion this was an issue because my computer would occasionally flash 4 amber lights and two white lights from the charging light, an indication of memory failure (see link for reference).

To check this further, you should open BIOS setup on startup (spam F12 when DELL screen flashes), scroll down to the memory section and note the status of DIMM_SLOT 1 and DIMM_SLOT 2. Provided you have dual memory sticks like I did, both of those should be visible. If you have two sticks but one slot says that it is empty, that means that particular stick is probably dead. In that case, you will have to open up the computer and take out that particular stick, there are numerous resources online to demonstrate how to do this. Provided this was the issue, your computer should run smoothly, just with half the memory. You could get the stick replaced, but so far I have not and have not seen any significant performance drops. Good luck and I hope this helped, it took me two months to fix this and I hope it takes less for you!
