Hey everyone,
I just upgraded my CPU, motherboard, and RAM, but now my PC keeps shutting down unexpectedly. It boots up fine and can complete the POST, but it shuts off abruptly whether I'm just idle, downloading games, or playing. I have to reset the PSU by turning the power switch off and on to get it back on after these shutdowns. I think there might be an issue with either the motherboard or the PSU because I sent both back for RMA. I got a replacement motherboard, but the PSU passed the check, so I have my old one back, yet the problem continues. I also noticed that the case gives me a shock whenever the PC is turned off.
I've tried quite a few software fixes, like reinstalling Windows and disabling fast startup, and hardware solutions, such as using a new power strip, plugging directly into the wall, and even starting without any I/O cables from the case.
For reference, here are the specs of my old and new builds. My old setup worked perfectly:
- **Old Build:**
- Case: Lian Li Dynamic Evo XL
- Motherboard: Asus Prime Z370-P
- CPU: i7-8700K
- GPU: 1080 Ti IchillX3
- RAM: 32 GB 3200
- Storage: Samsung 990 Pro 1TB
- PSU: 1000W FSP Hydro Ti Pro (1 year old)
- **New Build:**
- Case: Lian Li Dynamic Evo XL
- Motherboard: Asrock X870E Nova (BIOS v3.20)
- CPU: Ryzen 7 9800X3D
- RAM: 2x16 GB 6000 Vengeance CL-30
- GPU: 1080 Ti IchillX3
- Storage: Samsung 990 Pro 1TB
- PSU: 1000W FSP Hydro Ti Pro (1 year old)
I'm really stumped on what could be causing these shutdowns. Any ideas? Thanks!

It's also a good idea to make sure the PSU is truly functioning well since it can be tricky to diagnose. If all else fails, you might need to consider testing with a different power supply entirely, just to rule that out.
Try booting your PC outside of the case with minimal components first. Just keep the CPU, one stick of RAM in the A2 slot, and use the onboard video instead of the GPU. Doing this can help you rule out case-related issues or grounding problems that might be causing the shutdowns.
Have you checked the minidump files for any BSOD logs? If you can start Windows normally or in Safe Mode, look in C:WindowsMinidump for any crash logs. If you find any, zip them up and upload to a file sharing site. We can analyze them for clues to what's causing the shutdowns. Also, if you need a guide on how to adjust your dump settings, check out some tutorials online for creating minidumps. That could really help in diagnosing the problem.
