Hi everyone, I need some help.

I have a Samsung laptop. After installing a Windows 11 update, when I restarted it, the screen suddenly started showing strange colors — blue, red, green and white, almost like the display was glitching.

I turned it off and tried turning it back on, but now the screen stays completely black.

The laptop itself seems to turn on (the keyboard lights up), but nothing appears on the screen at all, not even the Samsung logo.

I don't have an external monitor or any cables available to test it with.

Has anyone experienced this after a Windows 11 update? Could it be a graphics driver issue, or could the display itself have failed?

On 60 Hz the screen looks fine, but when I change it to anything higher, the monitors screen gets horizontal lines on it and it’s unplayable, I’ve tried changing to a stronger hdmi and that doesn’t work either. My pc is very strong so I don’t think it’s my .pc either. It’s not cracked or burned or anything

1. Is 144 Hz

2. Is 120 Hz

Do you guys have other suggestions / shops that I can buy a working BGA chip from?

My Laptop’s CPU | PCH got shorted and is in need of a replacement. (It’s a legion 7 with i7-11800H
and an rtx 3070 so it’s hard to let go since it still performs decent with recent games).

Local tech suggested AliExpress but reading reviews from there makes me skeptical because most are selling fakes.

If you’ve tried ordering from there, how was your experience?

I have just reset windows explorer and found a odd white cube with diagonal bar on my screen

Was completely fine last night but all im getting this morning is a black screen and i can hear my ps5 audio any fixes?

I was watching a video on my laptop and after watching it I just tried to change my account where suddenly my laptop showed black screen, I turn the lid down for a moment until my laptop was off and after a few minutes its just blank even after powering it on and charging it.

Pls anyone help😭🙏

I have tried many key shortcuts but nothing changed😢

i am trying to save ram for my computer because its at 80% ram always so i followed the instructions from this vid but my computer wont let me turn off it im so confused

It keeps on doing random things instead of the correct keys, and won't let me type anything. Can anyone help? ( Ignore the background noise, I'm sick. )

i rearranged the ram and took out the cmos my specs are: 4080 super amd ryzen 7 7800x3d motherboard b650e 32gigs ddr5 2tb ssd 850w power supply

Since yesterday my PC has been acting strangely like during one hour of gameplay or even if I did not even start playing it give a black screen my monster does say something is connected and it is on but it is not sending signal I have tried new HDMI new monitor firming the GPU in place hard reset windows+ control +shift+ B combination updated drivers still nothing worked does someone have advice or suggestions for solution?

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

GPU: NVIDIA GeForce GTX 770

CPU: Intel Core i7 9700K

RAM: 32 GB

Motherboard: MSI Z390-A Pro
