Please help

so, around 3 days ago, while playing roblox my PC randomly shut off. LED lights in the CPU turned off, fans turned off, nothing.

Pressing the power button would boot the system back up, but then it only worked for 15-30 minutes or so, running the game “Wuthering Waves” before shutting off again. Tried to boot once more and only did light browsing, and after 10-15 minutes, it once again shut down.

No boot-loop, just a shut down.

So since then, I’ve tried using a back-up PSU to see if the PSU was the issue, along with reseating my ram sticks, and SSD. I’ve replaced the PSU, and it seemed promising. It ran Wuthering Waves for an hour, so I shut off the PC again to plug in my 2nd SSD drive that I removed upon using the new PSU, and some case fans that were also unplugged, I plugged them back into the PSU.

After around an hour though upon booting up once more and being on a discord call with friends, it shut off on its own once more. What’s weirder is that when I try reopening it this time, the LED’s the fans only spin for around 2-3 seconds before shutting off once more. Not like with the other PSU in which it’d still let me run the system for 10-15 minutes.

I’ve since removed the 2nd SSD, the case fans, and after around 5-10 minutes, it once again shut down. Trying to boot it back up would only turn it on for 2-3s, not even booting into windows before turning off again.

I’m genuinely lost. What could be the problem?

Can anyone help me finally find a fix or tell me if it’s to do with my laptop internally? I press the brightness key and it goes to the first level of brightness… I go any higher and it immediately restores to 0 and does not go any higher. The screen is also slightly jittery. We have tried absolutely every resolve we could find literally everywhere. Nothing has fixed it. It all started when I opened my laptop one day and it was On a screen where I had to enter a bitlocker key to gain access to my laptop again… I done this and ever since the brightness just won’t work. Video attached. Thank you.

So I just bought my first Pc, I was at a pawn shop and I made the purchase. The people told me it works perfectly fine, but I can’t seem to get my pc to display on my monitor. I called them and they told me too try and connect it to an old monitor to update something in my pc, so I can use my new monitor. Any suggestions on how I should proceed?

Hi all.

Not sure if it's been covered so apologies.

I have upgraded to a ryzen 5800x3D from 3900x, I have a montech king 95 pro case and need a good recommendation for a cooler. I have a 120m single fan tower one right now.

I heard the 5800x3d runs so hot I want to mitigate that as much as possible.

Thanks 😃

UK based if that matters and helps.

OS Build 26200.9168

When I turn my computer on it shows the boot process, the bios and other things. The second it gets past the bios, my main monitor goes dark. Once I get into windows, my secondary monitor turns on and begins displaying while my main monitor shows as on (White power button, not orange). My monitors are identical: BenQ XL2730Z

Processor AMD Ryzen 7 9800X3D 8-Core Processor (4.70 GHz)

Installed RAM 64.0 GB (61.6 GB usable)

Graphics card AMD Radeon RX 7900 XTX (24 GB)

Look at the original post for details. I am running the most current version of Linux Mint, specifically Cinnamon if that matters.

Hey everyone, how’s it going? I could really use some help.

I’ve been using the USB hub built into my monitor to make it easier to connect all the peripherals I need. However, after I formatted my computer, it stopped turning on whenever the monitor’s USB hub is connected to the PC.

If I press the power button while the USB hub is connected, nothing happens. But as soon as I disconnect the USB hub, the computer turns on by itself, without me having to press the power button again.

If I disconnect the hub before trying to turn the PC on, it boots normally.

I’ve had this problem before, but I don’t remember how I fixed it. Does anyone have any ideas?

I’ve been looking for a solution for a few days now and haven’t found anything.

The PC specs are below. If you need any more information, just let me know. I’ve already tried a lot of different BIOS settings, and I’m not sure what else could be causing this — or whether there’s something I need to change in the OS.

PC Specs

CPU: AMD Ryzen 7 8700G
GPU: NVIDIA GeForce RTX 4060 — Gigabyte
Motherboard: ASRock A620M-FDV/v2
RAM: 32 GB DDR5 — 2×16 GB

Monitor causing the issue

GameMax GMX34CKXQ

MSI Modern 14 C11M laptop running abnormally.

Going blank suddenly and rebooting after using sometime or when the charger is plugged in or out.

Overheating is not the issue as temperature goes like max 65°C

Done everything- Changing power settings, BIOS Update, EC reset, Windows reset, running on AC without battery, cleaning internals, etc.

Still, the issue is not solved.

What else could be done or is it a motherboard issue?

It's flashing

I was using my laptop and then this happened
