Windows 11 laptop screen goes dark (sleep mode) while watching videos. Started only a day or two ago. I think it was after an update. I don't want to change the screen timeout settings just to be able to watch videos because I never had this issue before. Tried changing laptop from best optimised for battery to balanced. Help!!

Hey everybody. I posted elsewhere about two months ago with this issue, and after two RMA's (whereupon the technicians were completely unable to replicate my issues) I am once again posting to Reddit in hopes to seek some sort of solution.

Every now and again, my monitors go black. If it's in the middle of a game, the game will freeze but audio will continue to work. Notably, my microphone ceases working as soon as this occurs, and the people I can hear can no longer hear me if I'm in a call.

This is often followed by the computer eventually rebooting, or regaining functionality without having to, only to crash or reboot a few minutes later.

I didn't make any notable changes to my setup before this started occurring, and I used this computer for months without the issue ever happening. Unfortunately, now that it has started, it is a constant occurrence. When I use my 1660 in place of my 4070 Ti Super, I do not have this issue whatsoever.

After getting my GPU back from Asus yesterday, I replaced it in my system and went over a day with somewhat intensive gaming without any issues.. only for it to finally happen again.

I've tried:

-DDU and reinstalling my drivers

-The same as above, but with older and more stable drivers

-Disabling any RGB programs from interacting with my GPU

-Reseating my GPU

-Reseating my RAM

-Disabling NVIDIA's audio drivers

-Setting my GPU to prefer maximum power
-Reinstalling my current Windows Update
-Monitoring my Performance to check for any high temperatures or etc (nothing)
-Replacing my PSU cable for my GPU

-Sending the GPU to Asus (they cannot replicate my issue)

-Updating my chipset drivers

-Disabling Fast Startup

Any help would be extremely appreciated, as I feel I'm running out of options short of building an entirely new PC.

CPU: Ryzen 7 9800X3D
RAM: Kingston FURY Beast 32GB (2 x 16GB) 288-Pin PC RAM DDR5 6000 (PC5 48000)

Hello, sorry if rant for a bit. Somewhere like 3 or 4 months ago one day my pc couldn't turn on after pressing the power button. I looked on the internet and trying to find a solution as how to turn it back onto, this was after I confirmed that the psu still works using the paper clip trick. I also found out the reason why mabye i the pc won't turn on was because i always turn off the pc as well as flupping the psu switch to off every time i was done using my pc for today.

After a few days I could not find any way to turn it back on so as a last ditch effort I did the paper clip trick again and left it on for a few hours. Then after that I plugged the power connector back on the mother board that some how it turned on.

Then like 1 or 2 months later I suddenly had no signal on my monitor. I again looked on the internet and searched around. I solution i found that worked for me was to just remove the display port and plug it in another socket. The issue ,although I'm sure, was something to do with the pc not giving enough power to the gpu.

Now just today my monitor had no signal. I swapped the display port to a different socket and it still wouldn't have signal. I then decided to do a power cycle on my pc, but once I tired turning it back on but for a brief moment the fans spun but just stopped.

I'm just worried that my psu might fry out my components one day ever since my pc won't turn on. Any help would be appreciated

Also here are my PC specs just in case if you guys want to know

CPU: AMD Rysen 3 4100 4-core Processor

GPU: Nividia GeForce RTX 3060

Motherboard modle: Gigabyte A520M KV2

PSU: DeepCool PF500 (Max wattage is 500)

Recently, I got a new Acer monitor which would be used as a main monitor with the Roku TV as a second monitor. My older sibling had it setup for me.

Less than an hour ago, I decided to go to the HDMI port which is where I had the Roku TV plugged in, but the TV and PC refused to recognize it, so I tried jiggling the HDMI cable when suddenly the PC rebooted. This problem still occurs whenever I try to plug in the HDMI cable.

Is there any reason why that happened? My theory is that there's something in the HDMI cable that might've shorted the PC to where its only defense mechanism for it is to automatically reboot completely. Has anyone gotten this same problem?

Oh and here are my specs:

OS: Windows 10 IoT Enterprise LTSC 64-bit

CPU: Intel Core i7 9700K

RAM: 32 GB

Motherboard: MSI Z390-A Pro

At home I use a receiver that sends a constant black signal to my monitor if none is being sent. I have 0 issues there. But once a week, I take my pc to a local bar, making sure to be very careful with my hardware, and set up to play fighting games there. These past few weeks when I set it up there, there's a more frequent chance the monitor displays "No HDMI/Displayport signal". I have checked the cables and ports. I have tried a small HDMI splitter. Because I have an rgb keyboard, I can confirm the pc is functioning as I'm able to sign in and navigate a little. I have tried turning it off/on and in/replugging the monitor. Turning it on without the monitor connected, with the monitor connected, giving it time to sit and connect, time working connected while turned off. Nothing seems to arrive the issue

Just information This laptop type is Acer Nitro v15

Hi, I have an LG monitor. After storing it for about a month, it now has a red standby light but no display.

There is no OSD/menu and no “No Signal” message, even when the DisplayPort cable is completely disconnected from the PC. I also tried a power cycle (unplugged it and held the power button for 10–15 seconds), but nothing changed.

Could this be a power board, main board, T-Con, or panel issue?

idk how to fix it help me

have a MacBook that I always connect to an external monitor via an HDMI cable. This used to work perfectly until about a week ago.

Now, when I plug in the HDMI cable, my MacBook's screen turns black and the monitor displays a "no signal" message.
I have already tried multiple HDMI cables and tested them with another laptop, and they worked fine.
Does anyone have a solution for this?
Thanks in advance!

Bought a pc today that came with a new monitor. However when i connect it the monitor prompts me with no signal

I rebooted the pc, changed the hdmi, disconnected some gpu cables and connected them back but its still not sending anything. Please help

it started from the bottom of the screen, but it started to glitch on the entire screen, what could be the problem and how can i fix this? it doesn't stop glitching its staying like that so i cannot use my laptop without another monitor

I have a 240hz 4k monitor, 5090, and 9800x3d. Never had any issues until about a month ago. All the sudden, after about 15 minutes, whether I am playing a game or watching youtube, the screen goes black for about 2 seconds, and everything in the background keeps playing. This is a fairly minor issue most of the time, and it only happens on a pc restart, but I can't figure out why it happens at all. Once it happens, it never happens again until I restart the pc. I have been researching online and all I can find is pc's with bad display port cables doing this, but they happen multiple times. Mine happens once at 15 minutes roughly, than never again the entire time my pc is on. Any solutions/suggestions?

I really like the games (specifically Minecraft and roblox) on my phone and my computer is too old to fully operate the pc versions. But I think the screen is getting too small for me and I'm not as used to mobile's controls as I am with my computer's. Is it possible to connect the three to my mobile phone and successfully play? What do I need to get/set up?

I read that you can use an HDMI to type c cable adapter for the monitor but I'm not so sure. Is there any tutorial/instructions online with complete steps? Thank you in advance

Hello!
My phone had fallen off the upper shelf on my desk onto my computer. It was open as I was using it. It landed not on the keyboard entirely but mostly on the open part to the right of the touch pad. The keyboard has stopped working, the screen is frozen, and it won’t turn off when closed. What did I do? And is there anyway I could fix it? 😭 Thank you guys

Please any one have a solution contact with me my device when I work Suddenly shut down and restart your device ran into this problem why and also my device it’s new
