Specs Gigabyte z68p-ds3 motherboard intel core i5 2500k I did have a graphics card but I removed that and using on board at the minute and it still restarts. I have disabled windows from shutting down in order for it to display a bsod but it doesn't it just shuts right off. In event viewer I get kernel-power errors after this shut down. I have tried a lot of stuff already found online but nothing helps. All drivers are the latest from the gigabyte website and I have uudated to the bios to version F9. Is there any way i can get the system to show a bsod to try and narrow this down? Thanks
Are we sure the power supply is adequate and not starting to fail? Any other PSU you can plug in to check?
