Dell Inspiron 3520

I got this laptop earlier today that the client states that the screen gets fuzzy and jumps around some. However I cannot get it to "mess up". I was wondering if a cable connection to the screen was loose but after opening up the case to look at the connections they all appear to have a strong connection.

Any suggestions on what else it could be. Company doesn't want to throw away the laptop if it could be a simple fix.

Reconnecting the LDVS cable has "fixed" it for me in the past, sometimes only temporarily though

Does it "mess up" when under load or pure random? Discrete or integrated graphics? Stress the thing with Prime95 and/or
Aida64 and see what happens.

Seems like it is just random. I know that she isn't using the laptop for much more than running internet and Microsoft office. I am stressing with prime95.

When going to the website the screen did just flicker at me.

I went looking for the post that mentioned the LVDS connector on the MB having bent pins but couldn't find it quickly. Anyway, check that connector with a magnifying glass to see if they have been bent so the cable connector doesn't make full contact. I also came across the following that may suggest other things to check:

Graphic problems like that are usually due to (in approximate order of frequency, in my experience) a faulty screen, faulty or poorly connected video cable, GPU problems, bad memory/memory sockets, or bad memory attached to the MB). I can't remember the time it was caused by software, though it can happen. Video problems can also be due to a LVDS connector whose pins have become bent/weak and on longer make good contact.

I would suggest booting a Linux live CD/flash drive to eliminate software as the cause.
