I recently upgraded my graphics card from an NVIDIA GeForce RTX 3060 Ti to a 5070 Ti and also switched my power supply unit from 650W to 850W. Since making these changes, I've been experiencing frequent crashes and blue screens while playing games, typically around 30 to 60 minutes after starting. I've tried uninstalling and reinstalling all my drivers, but the crashes continue. Could this be due to a temperature issue, or do you have any other suggestions? Here are my system specs for reference:
- Processor: 12th Gen Intel® Core™ i9-12900K 3.20 GHz
- RAM: 32 GB
- Storage: 1.82 TB SSD (Multiple models)
- Graphics Card: NVIDIA GeForce RTX 5070 Ti (16 GB)
- System Type: 64-bit operating system
- Motherboard: Z790 AORUS ELITE AX DDR4
After using BlueScreenView, it seems the crashes were related to ntoskrnl.exe.

It sounds like your new GPU might be the issue. Have you considered reinstalling your old GPU to see if the crashes stop? Sometimes, the new card can have its own issues.
You might want to completely uninstall all NVIDIA software and then reinstall it cleanly. Also, check your event log for any unexpected shutdown errors, as it could point to a faulty PSU.
To get a better look at what's going wrong, you should collect dump files from your crashes. If you can boot into Windows normally or through Safe Mode, check C:WindowsMinidump for any files. You can zip them up and share them through a file host site.

Here's the link to my minidump files: [https://www.mediafire.com/file/2ol8es5zjy7osod/Minidump.rar/file](https://www.mediafire.com/file/2ol8es5zjy7osod/Minidump.rar/file). Let me know if you need anything else!
