BSOD after 1 or 2 hours of using my PC (not necessary gaming)

Hi VerziDo,

Welcome to the 7forums.

The errors are 0x124 WHEA_UNCORRECTABLE_ERROR (Windows Hardware Error Architecture)
This means that there are problems with your hardware, but this error could also being caused by overclocking or faulty drivers.

If you are overclocking anything, revert back to stock while troubleshooting and test the system.

What are the CPU temperatures when Idle and under load?

Please run Prime95 to test the CPU

Diagnostic Test

 CPU TEST

Run Prime95 to stress test your CPU. Prime95 - Stress Test Your CPU - Windows 7 Forums

   Warning

Your CPU temperatures will rise quickly while under this stress test. Keep a keen eye on them and abort the test if overheating occurs.

Using the !errrec command on the 2nd parameter reveals that there is an internal error reported by the CPU, although the processor is not the same in every dump the bank is.
