Dell XPS All-In-One Monitor flashing


I have a Dell XPS All-In-One that recently began giving me the error: Command at 0x0000000000000000 at referenced location 0x0000000000000000 cannot be read. To solve this issue, I had to totally format the drive and install windows again from a separate installation media. Since then, I've updated all drivers, ran the Dell driver update utility, and Dell diagnostics. However, the screen continues to go black every couple of seconds and or dissolves into a bunch of random horizontal lines.

Any assistance would be greatly appreciated.

Thank you,

Found this thread on Dell's site -

If it passes the tests but still flickers, it's a video card issue. Unfortunately on the all in one models, this means replacing the whole motherboard. I'm guessing it is out of warranty, right?

Go to the Dell Support site for your specific model and download BIOS, Chipset and Video drivers. Install all of these.  This should work as these are the drivers that affect the screen.

If not, contact Dell Support and get the Recovery Media for your machine.

Also, there should be a F12 boot option to run diagnostics.  To me this sounds like a hardware issue.

Download Memtest and boot from it, then let it run a while and thoroughly test your RAM. Could be bad memory.

How old is the PC?
The Dell built in tools will test the memory as well.

I downloaded all the newest drivers for the chipset, bios, and video cards straight from Dell. They seemed to work for a little while, but unfortunately the glitch started right back up after leaving the system on for more than 30 minutes.


I've launched the diagnostic, but the screen is still flashing off and back on. When it's on the color bars look good, but the on/off thing continues.

You know it. Always is. All the hardware tests came back fine, but I was afraid that it was on the dying side, but wanted a second opinion on the matter. Thank you so much.
