well, I tried to update the bios, and while it was starting the screen went white and now I don't know what is happening with the pc. I know you are not supposed to interrupt the bios update, but I don't know where it is at in the process.... any suggestions?

I'd suggest updating the System Setup(BIOS). Please follow the steps in link below to safety installed the latest BIOS version.

How to Update BIOS (Official Dell Tech Support)

You mention running diagnostics for the display, you were referring to the Dell LCD BIST Test ? If no, follow the steps in the link below to run test.The Dell utility is a built-in diagnostic tool that helps determine if the screen abnormality you are experiencing is an inherent problem with the LCD (screen) of the computer or with the video card (GPU) and PC settings.

Note: If you do not detect any screen abnormalities in the built-in self test mode, the laptop LCD is functioning properly. Check the video card (GPU) and PC settings. If you do notice any abnormalities in the built-in self test mode, you may get the laptop LCD repaired/replaced if it is under warranty by contacting Dell Technical Support

Apparently I have the latest BIOS, and my screen still goes all white after a few minutes(which makes it hard to get anything done). Any other suggestions?

Yes, I have run the LCD BIST test. It shows no problem. I do not know how the video card(GPU) and PC settings could contribute to a random screen failure. Like I said when it does this, I hit the power button briefly to sleep, then a couple of minutes later I hit it again to wake up and the screen is back. I got on this board because I cant help but think I am the only person to ever have this happen. None of the other settings have been changed. I have a new PC I am using but this is the only thing wrong with the other one I am writing about. Seems a shame to just throw it away. Thanks.

If the system still is experiencing problems with the screen after installing Chipset and Video drivers, I suggest contacting Dell Technical Support for further assistance in the link below.

Drivers for video cards, also known as video adapters, graphics card, display adapters and video boards. Video drivers control how data is passed between a PC and its display (monitor or built-in LCD). In some cases, a driver allows the user to adjust display properties such as refresh rate, color depth and screen resolution.

Thanks for your suggestions. This computer had a windows issue, but was having the screen white problems before. I loaded a fresh version of Windows 10 home onto it after I got my new PC. I believe it has all of the correct drivers on it. I do not believe that this is a software problem. The reason I got on this site was to see if anyone else has had this problem. This PC is out of warranty therefore I am trying to fix it myself.

Been having same problem with my Inspiron 15 5565 Windows 10 (out of warranty one month!!).  Have a post that I started late last week.  Have tried BIOS update also and problem continues.  

Thanks for the response. I too ran all of the diagnostics and it shows NO hardware problem, and I have a fresh install of Windows 10 Home.  I finally called the out of warranty Dell line. I'm gonna send them the PC for extensive diagnosis by Dell(39.00) includes shipping, to see if it is worth fixing. I have a new PC, but the only thing wrong with this one is the white screen thing(seems a shame to just pitch it). They said new screen is about 150, but if it is just cable re-routing would be about 50. Thanks again for the response.

Hi! 

I'm having the exact same issue, and it's seriously annoying.

I know it's 2 years later, but, were you able to fix it?
