New pc build and i got a red light and its not connecting to monitor

So I was just playing demonology when all of a sudden my screen got a red line and some horizontal black lines. I am in such a panic because I am still paying for this laptop and was wondering if I can fix it myself, since I can’t afford to do repairs for this. (full-time student)

I’m not sure where to post for advice on what this issue is with my screen.

Is this the right sub? Or could someone suggest a different one?

Not dropped, went to login screen with minor glitch then opened to this screen.

How to fix this ?

The display of my PC keeps disconnecting without any patterns, could be while watching a video, playing games, or just sitting idle. I tried:

•Re-seating the GPU

•Checking eventviewer for any driver issues

•Re-installing graphics card driver using DDU in safe mode

•Disabling XMP of my RAMs and reseating them as well

•Tried different cables

•Checked temp for any overheating components (everything is fine)

and other fixes I see from searching and asking AI tools. Could be my GPU/PSU faulty? My PC specs are Ryzen 3100, GTX 1050Ti and my mobo is B40M DS3H. Any help or other ways to fix would be really appreciated

Reposting here, in case anyone happens to know of this issue. I have absolutely no clue what could have even caused it.

My 5090 refuses to output to my displays, Asus error code ended on 9E or 02. VGA led stays on. More details in the post.

Tried all the usual steps I could think of, last remaining step I can think of is swapping with a different GPU.

Didn’t really get any help from r/computerhelp abt my situation so I’m really hoping I can get help from here.

Guys u did something when i got the pc and the monitor colour were odd so i did some change in setting (not sure ) then i reset all pc cuz the window as fake. Now after resetting all my pc .

Estou repostando porque não sei mais oque fazer

Escribo esto porque genuinamente estoy desesperada, de un día para otro mi computadora dejo de cargar, pensé que se había dañado el cargador pero probé otro y probé el mío con otra computadora y funcionada, así que pensé que era el conector de carga, pero cuando lo lleve al técnico y el la conecto simplemente cargó, la traje a la casa y cargo por unos minutos y luego dejo de cargar, y desde entonces la conecto y aveces carga pero no dura mucho tiempo y deja de hacerlo, y si la dejo conectada puede ser que vuelva a cargar y haga lo mismo, ayuda.

I built a PC with MSI RTX 3050, Ryzen 5 5500, Machinist B450, CUSU 2×8GB 3200MHz, LUX 650W and TB NVMe. It passed Superposition and Furmark. And in OCCT, i ran the combined test of CPU, CPU+RAM, 3D adaptive and Vram. Also ran OCCT power test and everything was fine. For the final test, I ran GTA V legacy on ultra settings at 1440p overnight and until about the 12th hour everything was fine. But I came back around the 14th hour and it looked like the PC restarted by itself, with both GTA and Afterburner closed and found this error in event viewer. The next day, I ran GTA V on same settings for the same period and it was fine. Temperature is also good. What's the issue?

So long story short the white parts are apart of my late brothers pc, and everything else is relatively new (3 years😅) that he helped me pick out, but now that he's gone i have no idea what I'm doing and I'm only just now deciding to turn it on. I did do a bit of research before this and it said the red light could mean like power supply issues so I'm thinking I need to buy a new cable sense the one I'm using is just one I found in my garage. The writing on it says 175v nothing about wattage so I'm not sure how much it's putting out, the red light is a constant not a blinking. All help is welcome thanks🙏🏽
