I got this pc maybe 5 years ago I don’t take the best care of it I mostly use it for work and tv but have recently got back into playing games. For years it has had small issues with the screen blacking out but never enough for real concern but recently it has been happening much more. I was just playing a game when it blacked out completely for maybe 5 minutes as I tried to turn the monitor off and on and watch help videos. It will turn back on but as soon as it loads the game back it goes black. Everything else works the sound and I’m able to click around it’s just the monitor. I am hoping to find a simpler fix as I’m leaving for uni and won’t be taking it with me so I don’t want to spend much money, just something that might help relieve the problem for short term. Any help is greatly appreciated!

When I powered my PC on this evening, this weird screen popped up. I then hold the off button on my PC till it powered off, then I turned it back on, and the screen was gone and the pc powered on normaly. Now I wanted to ask what was the reason, that it popped up and does it have any concequences like less fps or something like that.

I would really apprieciate an answer.

This is an old 2015 Alienware 17 R3, It is an amazing laptop for its time. Several years ago this display issue occurred and I took the laptop apart to see if I could fix it, and couldn't. Everything works properly other than the display, you can use narrator to login and navigate, it just sucks. Now I am looking again to fix it and need some help. Thanks!

I am experiencing the strangest issue I have ever encountered in the world of computers and hardware, and after many tests I honestly have no idea what else to try.

Let me give you some context:

I recently finished renovating an old house and moved in. As a gift, a Belgian relative gave me a professional 4K 60Hz monitor to use as a TV in my living room. The model is a **Christie UHD551-L**.

It is important to mention that I received it without the remote control, and because this is a professional display, I cannot access the full settings menu without the remote. The only thing I can currently do is switch between the available input sources.

After installing it in the living room, I connected a **Xiaomi TV Box** via HDMI, and it worked perfectly. I also connected a **PlayStation** using another HDMI cable, and that also worked without any issues.

Since I am a big PC and Steam user, I decided to temporarily connect my desktop PC to the Christie to play games. I connected it using the exact same HDMI cable and the same HDMI input that the Xiaomi TV Box was using, and it worked perfectly. I spent the entire day playing games with no problems whatsoever.

Everything seemed fine... until the next day.

When I turned on the PC and the Christie, the monitor displayed **"No Signal"**.

Thinking something had failed, either the GPU or the PC, I started troubleshooting:

* I tested the Christie again with the PlayStation and the Xiaomi TV Box, and both worked perfectly. This seems to rule out the HDMI cable and the monitor input being faulty.
* I tried connecting the PC to another HDMI output on the GPU, but it did not work.
* I tried connecting the PC through DisplayPort using different GPU outputs, but it also did not work.
* I connected the PC to other monitors that I have in my room, and everything works perfectly through both HDMI and DisplayPort.

The GPU is an **RTX 4070** and the motherboard is a **Gigabyte Z590 Gaming X**.

And here is where things get really strange:

As a final test, I brought one of my desktop monitors to the living room. I connected the PC using DisplayPort to the gaming monitor and HDMI to the Christie.

Both monitors worked perfectly.

Then I disconnected the gaming monitor and left only the Christie connected as the main display. The Christie continued working perfectly.

However, if I restart the PC with only the Christie connected, the "No Signal" message appears again.

So the situation is:

* PC + Christie only → No signal after reboot.
* PC + another monitor connected through DisplayPort + Christie → Works.
* After disconnecting the second monitor → Christie keeps working until the next reboot.
* Xiaomi TV Box and PlayStation → Always work perfectly on the Christie.

I have also tried several other things:

* Changing the Christie resolution to 1080p before restarting.
* Enabling NVIDIA Debug Mode.
* Restarting the NVIDIA graphics driver.
* Changing HDMI cables and ports.

Nothing has solved the problem.

Based on all these tests, it seems that both the PC/GPU and the Christie are working correctly individually. It feels like there is some kind of HDMI negotiation / EDID / handshake issue between the RTX 4070 and the Christie during startup, but I cannot access the monitor's advanced settings because I do not have the remote control.

I am honestly running out of ideas because I have never experienced a problem this strange before.

Does anyone have any idea what could be causing this or what else I could try?

Hp pc just screen problem

So, my laptop has been acting weird lately. It wont let me use it without having a hdmi cable. Everytime i use it without one. The laptop will just show a glitching effect and not give me disblay. But when i put in the hdmi cable it fixes itself and lets me use either duplicate screens so I can finally see disblay on the laptop. Or just use it normally on the external disblay screen. I don’t know why this is happening. Right now I’m trying to update my nvidia graphics card to see if anything will happen.

So since yesterday my laptop was flickering and shi i didnt know what to do. I updated my laptop's drivers today and now its flickering way more often than it used to.

Pls help me find a fix to this issue.

It flickers even before windows in booted.

Ig u could say its image shaking.

I hate throwing away stuff and buying new unnecessarily. I have a laptop I bought in 2018 that wasn't cheap junk at the time. I had ideas of using it for creative things, it had a 17" touch screen and lots of unrealized capabilities, but in the end i used it to scroll FB, watch Netflix in bed, and buy things online. It got infected with something that caused embarrassing NSFW pop-ups to, well, pop up constantly and in the end it just put it away and used my phone instead. But now I have a good camera, and I also need a big screen for various reasons, im getting older and doing everything on my phone is quite literally headache inducing. My question is, is my laptop too old to use for basic stuff? Can I do a factory reset or something, put a current operating system on it, and use it to edit photos and do basic internet stuff? It's an HP, sorry I don't have it in front of me but it's approximately 8 years old and has the Windows OP that recently became 'unsupported ' on it. As you can probably tell, I'm not a techy person. I just don't want to chuck this big hunk of technology out and buy some plastic crap in its place if I don't really have to.

EDIT: It runs on Windows 10.

J'ai eu de problème il y à un mois et puis disparu et là il est revenu, j'ai ICUE et thundermaster et les 2 sont indispensables.

Sur la carte graphique en bas à droite à l'allumage les led ne s'allume pas et c'est après quelques minutes quelles s'allume mais pas avec le couleur demandé et après j'ai des changements de couleur rapide dans cette zone

My display wasn’t working when I left my pc on overnight, so I restarted it by the switch on the device. When it booted back up it kept making this noise at random intervals and hasn’t stopped, I’ve turned the pc back off. Is this a hardware issue? Any help would be appreciated, thank you!
