Hi all,

So I previously made a post in the GPU sub-forum trying to get some help with my dead new-build PC. The thread is linked here: https://forums.tomshardware.com/threads/desperately-need-help-with-new-pc-thats-died.3612804/

The PC would crash and instantly reboot itself every few days. I originally thought this was a CPU overheating error but I bought a new fan and still experienced the crashes every few days. On Thursday of last week the PC crashed, turn on, crashed, turn on, and got stuck in a boot loop. From then onwards I wasn't able to get past the motherboard loading screen (B450 Tomahawk Max Arsenal Gaming logo).

After troubleshooting for the last 4 days, doing loads of different things (more comprehensive explanation in the linked thread), after some advice from a user on here I removed my HDD. Removing the HDD has allowed me to boot into my desktop and bypass the boot loop. For the first time in 5 days I could actually get to my desktop.

After trying to boot up so many times, my GPU was very hot to touch. It's fans spun on boot-up, then stopped when I was idle on my desktop despite the GPU feeling very hot to touch on the plastic (Gigabyte 5700 XT). After trying to run CPU-Z to see if everything was up and running, the PC yet again crashed. It booted straight back into windows and allowed me to get into the desktop again. After sitting on the desktop, I tried running CPU-Z again and it worked for a few seconds before I shut it down out of caution.

I then booted down the PC in fear of the GPU overheating.

Can anyone advise what the issue could be? I'm worried it could be a MOBO issue that's causing the MOBO to short circuit or something. I've tried moving RAM slots, 1 stick, 2 sticks, unplugging all PCI-e cables, etc etc (more comprehensive explanation of what I tried in linked thread)

Known errors during build:

(bare in mind the PC worked, playing high graphics games such as GTA on max settings, only crashing 1 time whilst playing. It crashed every 2-3 days during all kinds of strain from games to google)

  • Potential scratches to back of MOBO when trying to align with I/O shield.
  • Tiny bit of thermal paste (wiped off with a cloth) on the MOBO when fitting new fan
  • MSI drivers installed on a Gigabyte GPU (accident)
  • Potentially plugged keyboard into BIOS Flash USB slot (though I don't think this matters)
Any help would be massively appreciated. I can't tell if it's the CPU failing, the MOBO is failing, the Power supply could not be providing enough power, the GPU could be faulty, the GPU drivers could be faulty etc...
I don't have any extra parts to swap out and test, and I'm running a 3600 CPU so don't have integrated graphics.
I tried calling a local PC specialist who said he couldn't diagnose the issue over the phone, but taking it into his shop could cost hundreds in hourly rates to fix.

Again, I would be eternally grateful if anyone could help.

Hi all...

So I rebuilt the PC again, replacing the motherboard AND power supply...

and I just had a crash again playing FIFA 20... same Kernel Power 41 error.

What else can I try at this point? All I have left to RMA is my GPU, SSD, RAM and case...

I'm so sick of this now, it's ridiculous... :(

Edit: I've been getting errors that crash games (not the computer) when playing on Origin, the error is: "dxgi_error_device_hung the applications device failed due to badly formed command sent by the application. This is an design-time issue that should be investigated and fixed"

Could it be anything to do with the fact my graphics card is overclocked by default? (Gigabyte 5700 XT 8GB OC)
