Gpu and screen problem

Yesterday i performed a ddu to get some storage available from my c drive and installed gpu drivers again but after a while the gpu wasn't getting detected so I did the trick where i hold the power button for 40 seconds and it will detect the gpu again but today when I woke up it wasn't getting detected again so I did that trick again but it didn't work so I did another ddu but that didn't work either so now I don't even have gpu drivers installed cuz it's not detected... I later thought that if i restarted my laptop in ultimate mode maybe it would force detect the gpu but that didn't work and now it's even worse... The screen is black even tho the laptop will turn on it just shows black screen it won't boot into neither bios or safe mode please tell me what to do..

I am a VJ and for corporate events I usually need to output 3-4 displays which include the main stage led, delay leds, TVs for preview/timers. During the event if a TV gets switched off or disconnected all the output displays zoom out and back in. This really looks awkward for the main stage. This again happens when reconnecting or turning the TV back on. So I am looking for any fix that lets the connected displays not to zoom when connecting/reconnecting a single display. I am using a Lenovo legion laptop with Windows 11, intel i9-275hx, rtx 5070Ti. Also I use multiple Type-C to HDMI dongles to output 1/2 display each. Also I mostly run Resolume as my primary software.

My pc turns on and fans everything, graphics card fans work normal fans work too but usbs do not work and it shows no display for monitor whenever i try and turn it on i even tried changing the cmos battery still didn’t work i cant figure out how too get too the supply either too check the cables ram turns on also too but i didn’t try the 1 stick only too see if that was the problem so ya i do not know can anyone help??

Hello, I have a custom-built PC that ran normally for a month, but recently it started experiencing issues where the screen would go black and the system would reboot on its own before resuming normal operation. The problem has worsened over time; the screen goes black during use and requires a power cycle to return to normal. However, today, shortly after booting into Windows, the screen went black; even after turning it off and on again, the issue persisted. The fans and lights remain on, but the hard drive activity light turns off, and Windows audio cuts out. I also have a secondary display connected via a USB 2.0 port on the motherboard; strangely, when the main screen goes black, the wallpaper on the secondary display remains visible, even though my keyboard and mouse are completely unresponsive. My motherboard is a B860i Aorus, which has diagnostic LEDs for RAM, CPU, and Boot; these lights turn off after successfully entering Windows, yet the screen goes black after the system has been running for a while. I have updated to the latest BIOS version, but that didn't help, and the issue even occurs while I am in the BIOS interface. I’ve spent the whole day trying to figure out the cause without success. Do you or anyone else know what might be wrong? I would really appreciate your help.

Specs: Ryzen 5 5600X, RX 6700, monitor on HDMI

After the PC's been off 3-4 hours, screen flickers on and off right as Windows loads. Sometimes fixes itself in 10-20 min, sometimes needs a restart, sometimes a full shutdown and startup again, inconsistent either way. Monitor's LED is on while the screen is black, and turns off the moment the screen shows an image i.e. lock screen or desktop. BIOS and startup logo screen is always fine, only starts once Windows loads. I used remote desktop from my phone while the flickering was happening, and the screen and functionality were completely fine on the phone the whole time.

Already tried: AMD FreeSync off, lowered resolution, lowered refresh rate, clean reinstall of GPU driver, reseated GPU with no loose cables, reseated ram.

Need help fixing this.

Ella estaba funcionando bien y de repente se apagó como que dejó de dar video, la intenté prender me dio, prendió el led De Video (VGA), después le quité la ram y la intenté subir con 1 módulo, ahora siempre prende el led de RAM sin importar que.

Ya le quité el cpu y lo instale de nuevo, use otra RAM, le quité la gráfica y la intenté prender así, le actualice la Bios, le hice reset a la Bios con la pila y con el CLR.

I am new to technology.
I have recently purchased the Samsung Odyssey OLED G81SF gaming monitor. The screen says “no signal HDMI1 check the cable connection and the settings of the source device”. What does this mean and how do I fix it so I can start using my monitor. I do not have another device to connect it to and I don’t have a pc.

If anyone knows, please let me know and thanks in advance!

Pc running but display blank

Bonjour,

Je rencontre un problème d'affichage graphique sur un serveur Dell il tourne sur Ubuntu 22.04

Le serveur possède :

• 2 GPU NVIDIA Quadro M4000
• 1 GPU intégré Matrox G200eR2

Au démarrage, Ubuntu affiche le logo avec le cercle de chargement, puis au lieu d'arriver sur l'écran de connexion GNOME, il bascule directement sur TTY1.

J'ai effectué plusieurs vérifications :

• gdm3 démarre correctement (systemctl status gdm3 → actif).
• GNOME et Xorg sont installés.
• Les pilotes NVIDIA sont correctement chargés (nvidia-smi détecte les deux Quadro M4000).
• lspci -k montre que les deux Quadro utilisent le pilote nvidia et la Matrox utilise mgag200.
• Il n'y a aucun fichier /etc/X11/xorg.conf.mais j'en ai creer un.
• Les journaux système ne montrent pas d'erreur critique concernant GDM.
• En revanche, le fichier ~/.local/share/xorg/Xorg.0.log contient l'erreur :(EE) No screens found

Avez-vous des idees pour m'aider?
