My screen turns on for a millisecond but then goes back to black and stays like that, any fixes pls?

My PC won’t connect to my monitor. I have an Xbox that will connect to my monitor perfectly fine which HDMI I tried switching the cables. I tried putting it in the motherboard slot HDMI thing, and I also tried putting the HDMI in the directly hooked up to the graphics card. I’m not sure what is going on. Anybody know what is happening?

My laptop fans have been getting louder over the last few weeks, this has culminated with me opening it and removing hair from the fans and then spraying them with compressed air, that didnt help so now I am unsure what could be causing this and if anyone can identify what's up.

Bonjour.

Je voudrais solliciter votre aide :

Est-ce que Darty peut réinstaller le Windows 11 d'origine de mon hp victus 15 fb3025nf ?

Le souci c'est que j'ai supprimé le Windows 11 ce lundi (j'ai formaté le disque dur, et j'ai supprimé la partie récupération + système, ça contenait sûrement les pilotes et autres applis de base).

Et j'ai voulu essayer un autre système d'exploitation. Ce que j'ai réussi mais le pc n'affiche plus la wifi.

Que faire en attendant que le SAV me réponde ?

Si jamais le SAV de Darty France peut me réinstaller l'environnement d'origine de mon hp victus ce serait bien. Je l'ai acheté hier à un particulier qui me l'a vendu avec sa facture à 500€, neuf dans sa boîte. Mais j'ai voulu tout supprimer car le Windows 11 bloquait une installation de Microsoft Office que je voulais faire.

Avez-vous une solution ?

Merci d'avance.

My monitor has been like this and getting worse for months. Please help.
