I recently completed a new PC build and installed Windows 11 using a USB I purchased. After setting things up, I can log in and get to the desktop, but my PC unexpectedly turns off after a few minutes. Here's what's been happening:
- I was able to connect to the internet via Ethernet and started downloading updates. I walked away for a bit, and when I returned, the PC was off.
- Restarting leads me to the login screen, but it crashes right after logging in.
- I tried using Task Manager, but nothing slipped through as unusual in terms of resource usage. All drivers appear to be up to date, yet it powers down.
- Safe mode crashes right at the desktop login as well.
- I attempted to redownload the OS from the cloud, but it crashed again.
- I also tried resetting the system but it crashed again during the process.
I've reseated everything, confirmed my RAM is installed correctly, and even tried using just one stick while swapping them around. The cooling fans are working fine, so I'm puzzled. It feels like it might be a power or overheating issue, but my PSU is rated at 850W, which should suffice. I'm suspicious that the OS or drivers might be corrupt because I can't seem to initiate a proper redownload of them. Any suggestions on what I should do next?
Here's the hardware setup:
- **Motherboard:** ASRock B650M PRO RS AM5
- **Graphics Card:** ASRock Challenger Radeon RX 7700 XT 12GB
- **Power Supply:** Thermaltake Toughpower GF A3 850W
- **CPU:** AMD Ryzen 5 7600X
- **SSD:** Patriot P400 Lite 1TB
- **RAM:** Silicon Power Value Gaming DDR5 32GB (2x16GB)

You should definitely check the event viewer for any critical errors that could be causing the shutdowns. It can provide clues about what’s going wrong with your system. Try looking in the System section for specific error codes or warnings—it’s a good way to narrow down the issue.
Try booting your PC with the graphics card removed and connect directly to the motherboard instead. This can help identify if the graphics card is causing the problem. Also, double-check all your power connections, especially the CPU power cable—make sure there are no bent pins as they could be causing an issue.
