I've had my custom-built PC for over two years, and I've recently run into some serious problems. After playing Fortnite, my system crashed into a boot loop. I managed to fix it temporarily using some system checks, but after updating my drivers, I encountered a Blue Screen of Death (BSOD). I ended up doing a fresh install of Windows, but now I'm stuck in a boot loop again.
I've run MemTest four times, and the RAM seems fine, but I suspect it could either be a bad power supply (PSU) or another issue altogether. My PSU might be underpowered, and I'd really like to avoid costly repairs if I can help it.
Here are my system specs for reference:
- Motherboard: MSI PRO B550M-VC WIFI Micro ATX AM4
- CPU: AMD Ryzen 9 5900X 12-core processor
- Memory: Silicon Power GAMING 16 GB (2 x 8 GB) DDR4-3200 CL16
- Storage: TEAMGROUP MP44L 1 TB M.2-2280 PCIe 4.0 X4 NVME SSD
- Video Card: PowerColor Fighter OC Radeon RX 7700 XT 12 GB
- Power Supply: MSI MAG A550BN 550 W 80+ Bronze Certified ATX

You should definitely consider adding details about your CPU in your post, as it can help others offer more targeted advice. It's an important piece of the puzzle.
I checked your setup against MSI’s PSU calculator. Even with 4 fans added, it suggests you need at least a 563W PSU. Given your power-hungry GPU, you might want to consider underclocking or undervolting it as a quick fix. That could lower the power draw significantly. If you do BSOD again, snap a pic of the error code and share it for better troubleshooting. And since MemTest came back clear, I’d lean away from RAM issues for now—try testing your RAM sticks one at a time as well.
I did run into a BSOD with the error code 0xc0000001 before my fresh install. Here’s a photo of the error!
To really diagnose the BSOD, you should grab your dump files if you can. If you can boot into Safe Mode, check the Minidump folder on your C: drive. Having those files will make it easier to analyze what caused the crash. If you find the files, zip them up and share them on a file-sharing site that works well. Multiple dump files would be ideal for a thorough analysis.
Thanks for the reminder! I added it now.
