I'm here to assist with your PC issue. It seems the system won't boot, so let's figure this out together.
Hello! I recently purchased a new GPU and PSU, and everything functioned smoothly during my initial gaming sessions in Cyberpunk. However, when I attempted to enable the overclock preset in AMD Adrenalin, the system abruptly shut down with a black screen. It took several attempts to get the PC to start, as only the internal components lit up, but not the monitor, keyboard, or mouse. Once the PC booted up, I resumed playing Cyberpunk and adjusted settings in both the game and Adrenalin. A subsequent crash occurred again, requiring multiple tries to restore the system.
After restarting the game and playing without making any changes, I experienced no issues. However, upon closing the game and navigating to Windows, the screen went black after a short delay, leading to another crash. I experimented with different games and less demanding titles, but the recurring pattern remained consistent.
I attempted to troubleshoot by restarting the PC, but the issue persisted. All fans and lights were active inside the case, yet no display or input devices responded. I removed the GPU and used the built-in graphics, tested with a single RAM stick, multiple slots, and even disconnected the motherboard battery before reinserting it—without success.
I have limited components to work with, but any guidance on resolving this would be greatly appreciated.
System specifications:
GPU: ASRock Radeon RX 7900 XTX Phantom Gaming OC
PSU: Corsair RMe Series RM850e
CPU: AMD Ryzen 7 5700G
Motherboard: ASUS ROG Strix B450-F GAMING II
RAM: Corsair Vengeance LPX DDR4 3200MHz 16GB (2x8GB)
SSD: WD Black SN850 500GB M.2 NVMe SSD
This was the final setup before my PC went offline.
Was das Video mit einem 7900 XTX im System oder mit einer iGPU aufgenommen? Es scheint hochgradig gestört oder artefaktbelastet zu sein, möglicherweise sogar BIOS-Probleme. Die Qualität ist insgesamt schlecht, und es könnte sich um eine BIOS-Korruption handeln.
Mit der hochwertigen GPU im Modell wäre die Mindestausstattung vermutlich etwas wie Seasonic PRIME, Corsair AXi oder Super Flower Leadex Titanium.

Meine erste Priorität wäre ein neues PSU mit mindestens 1000W, aber das löst die Artefakte nicht.
Dabei hängt es davon ab, ob die GPU im Bau war oder ob eine neue CPU installiert wurde, da letztere in diesem Fall betroffen wäre.
The video was recorded using 7900 xtx in. I had to spend a significant amount on those parts, which means they are no longer within my budget right now, even though I can stretch the remaining funds a bit more financially. Are these high wattage requirements really essential? The card's peak draw was about 480w, which should provide ample power for other components, or am I misunderstanding?
The GPU consumes 355W and delivers 480W at full capacity, but have you considered transient power surges?
🤔
If you include those spikes, the GPU can handle around twice its rated TDP, which brings the potential to about 700W during short bursts.
On PCs, increasing wattage is generally safe. However, this situation falls short—will.
Hmmm... diagnosing it is tricky because there was significant artifacting or corruption when the GPU was active, and now the whole system doesn’t boot.
I’d start by disassembling the build. You’ll need to take it apart eventually.
So, extract the motherboard from the PC case and place it inside any cardboard box (a standard retail box works).
Remove: the GPU and all storage drives, including the operating system drive.
Also remove every RAM module except one DIMM.
Attach the monitor to the motherboard and check if you can see a power-up image.
If not, then one of these is likely faulty: CPU, motherboard, or RAM.
With two RAM sticks, you can also try using the second stick. But always test with just one at a time.
If it still doesn’t work, it’s probably between the CPU and motherboard—about a 50/50 chance.
Typically, if the power supply fails, the motherboard is the first to fail.
You might also think about sending your PC to a repair shop for a full diagnostic. They can confirm whether the CPU or motherboard is damaged (or both).
At the very least, you should aim for:
* A fresh, high-quality 1kW power supply (any of the three options mentioned earlier, or I can suggest more affordable but reliable ones)
* A new GPU (you can return your old one if AsRock accepts RMA; they may not if they suspect PSU failure)
* A new motherboard or CPU (it’s better to have a professional check both)
Rarely will both RAM sticks fail, but it’s worth testing.
But for sure, get a new power supply regardless. Since a failing PSU can destroy other parts too, and warranty doesn’t cover everything, it’s wise not to compromise on quality.**
I connected the old GPU and the PC started up smoothly, which makes me think the GPU might be the issue, maybe even the built-in one in the CPU. I'm unsure what to do next, but after speaking with the shop, I could just return the old power supply and buy a new one if needed. This seems like a reasonable first option. However, if my PSU is so poor it's still listed as A-tier on that site, am I misunderstanding? Could it be because of its low wattage?
review the first two links regarding your video for the motherboard bios
None of that appeared necessary during the installation of the old GPU. Even though I had the file on a USB drive, I updated the BIOS the previous week.
It's likely your previous GPU consumes less power, reducing pressure on the power supply unit.
Yea, at this stage I'm not really sure what to do. Cash out and upgrade the PSU and test it with the 7900 xtx? RMA the card and get an ASUS TUF card instead as that is similarly priced (the other xtx cards are 200-500$ extra, no chance i'm doing that). RMA both or just the card and test it with the RM850e PSU? If i just RMA the GPU, i might end up with the same problem again if the PSU is faulty. I also don't really want to give ASUS any more money, but that is the only XTX option if i don't want to sit for weeks waiting for the repair technician diagnose the Asrock GPU.
The content leans heavily toward a particular perspective, emphasizing Corsair PSUs while downplaying others. This bias is evident in the way certain models are highlighted and compared. For instance, an edit note on RMe states that despite being placed in a normal priority tier, it still falls under speculation, unlike Seasonic Vertex which remains in a more neutral category. Similar patterns appear in their PSU buying guide linked, where Corsair consistently appears at the top across various metrics, even for specific power ratings like 650W and 550W. The text also points out that reputable sources such as Hardwarebusters present a diverse range of options, each with distinct strengths in different categories like overall performance, efficiency, noise, and stability. This contrasts sharply with the cultists.network stance, which insists Corsair leads unconditionally. The main worry highlighted is a failed build, which could signal problems with the CPU, motherboard, or RAM, or issues with the power supply itself. It suggests testing the system with different PSUs to identify the root cause before concluding that the current setup is unsuitable.
