BSOD seemingly randomly. No new apps or hardware installed

Your motherboard manual: MSI P67A-GD53 Intel P67
MSI Global ? Mainboard - P67A-GD53 (B3)

All the CPU temps look good.

Your BIOS version is V1.12, which isn't listed on your board site.
There are 5 updates since yours, going by the date of your BIOS.
Improvements mentioned:
- Improved memory compatibility
- Improved VGA card compatibility
There are quite a few updates, which would indicate they were trying to fix problems.
With your issues I would update the BIOS to V1.19.
If you haven't updated BIOS before, let us know. There is the chance that it might fail and leave your board useless.

While at the MSI site check for any newer drivers.

To update the BIOS, do not do it from the OS or from internet apps. Use the CD or USB install method.
If anything intrudes on the system while flashing the BIOS, it can cause a corrupt BIOS and can leave your motherboard useless. If the Anti-virus decides to run while you are flashing the BIOS it can cause big problems.
