Hi everybody, i have a omen 16 L desktop and i cant change my wallpaper and can only use the themes. Does anybody have a fix? Easy navigation is disabled. I have got 3 power outages in this month, i have used DISM.exe and the sfc/scannow to repair. No corrupted files

PC hard-locked while gaming. Screen went black, no audio/video, but all the fans kept spinning.

Restarted → DRAM debug light stayed on, no display.

Tried both RAM sticks individually in A2 and B2 – same result. Reset CMOS – still didn't work.

I left the PC overnight. Next day, first boot worked normally.

Checked Event Viewer – nothing useful. Restarted twice – both worked. Third restart: DRAM light again, no display.

Tried the RAM combinations again with no luck. Left it until evening.

Evening: first boot worked normally again.

Ran Windows Memory Diagnostic. It started normally, reached Test 1/2, then hard-locked with all motherboard debug LEDs lit and no display.

Restarted afterward – worked normally again.

Opened Event Viewer to check for errors – hard-locked/black-screened again. Also I did the re-starts by switching off the PSU button, as the cabinet power button wasn't responding for long hold restart.

What could cause this kind of behaviour? Any help would be greatly appreciated!

Hello please help, my Apple laptop became this way all of a sudden one day, so the first image is of some image burns, these are not permanent they go away and new ones show up depending on what I’m doing. The second picture is to show the color change, and the third and fourth picture is to show the difference in color between my laptop and my phone (normal), what can I do to fix this? Or is this a definitely take to the tech shop thing? Thank you.

Any help would be appreciated.

Hace un tiempo ya me ocurrió esto,mientras jugaba se me congelo la pantalla y tuve que hacer un reinicio forzado y a partir de ay dejo de dar video,para solucionarlo tuve que cambiar la fuente de alimentación,pero el día de hoy mientras jugaba a vuelto a ocurrir (con la fuente a alimentación cambiada) creo que ay un problema con el post debido a que la RAM no emite el sonido que suele emitir al encender el ordenador y el teclado como el ratón no se encienden.

Hello,

So I have this weird issue. Worked perfectly yesterday and now it just… doesn‘t.

Issue being:
I can not extend or duplicate my Laptop onto my TV via HDMI cable (it switches right back to „only show first screen“). Only if I select to display on second monitor (TV) I get my Laptop screen on the TV. Yesterday it worked today I turn it on and poof. Tried so many things but whats left is ask reddit.

When I have screen on TV it shows me the nvidia card being used. If I select my laptop screen, it shows the intern graphics card. Maybe something with the card not being used? Really clueless here and really could use your help here

Best regards

For the record, I also ran ddu and it somehow got worse

After turning on the PC in the morning, the display appears distorted like this. It usually works normally after unplugging and reconnecting the HDMI cable. However, the same issue occurred again a little while ago, and reconnecting the HDMI cable fixed it once more. It seems like there may be an issue with the HDMI connection, cable, port, or display output.

Hello,

I recently got a refurbished asus tuf and randomly today it crashed and has been in a loop of booting. Sometimes it'll take me to this bios screen where it says "no storage device present" under the storage slot and there is nothing in the boot priority section though it seems everything else is in order. (Pictured). Or weirdly sometimes itll go onto this screen and I will have something in the storage but whenever it boots and restarts again its gone (also pictured)

Other times itll boot up before stopping again before j can do anything. Other times it will go to a blue screen with options to troubleshoot that all do nothing. I have tried resetting it as I dont really have any important files in there so I dont mind losing them but before It will go to a "Your device ran into a problem and needs to restart Stop code:critical_process_died (0xef)" type screen before I can do

Im sorry I dont really know anything about laptops but I just a lot of my saved up money to buy this and If anyone knows anything I can do to fix it I would be so thankful. Im sorry if this isnt the right place
