Possible solutions
- Run memory test
To launch the Windows Memory Diagnostic tool, open the Start menu, type "Windows Memory Diagnostic", and press Enter. You can also press Windows Key+R, type "mdsched.exe" into the Run dialog that appears, and press Enter.
- Corrupted Drivers
If the problem doesn't happen while in the BIOS settings screen (usually pressing the F2 key after pressing the power button) I would suspect a corrupted driver. First of all see if any drivers are corrupted by checking in the Device Manger. I would start with the Bluetooth. Just uninstall but don't delete the drivers and let Windows reinstall by clicking on Action > Scan for Hardware changes up in the menu.
- Defective Easily Removeable Hardware Components
If that doesn't work hopefully it is just an easily removeable hardware component with an intermittant failure. Try removing one at a time and testing each time. I would start with the RAM. For the RAM remove modules (usually there are two) one at a time and also try in each individual ones in each slot. Then Bluetooth, Wi-Fi, etc. Even an intermittantly defective hard drive could cause the problem.
