Random BSOD x124/Crashes

You have tested the hardware components, but also checked for driver updates?
The error 0x124 is often caused by hardware damage, overclocking or driver problems.

The cause is a read error with the level 1 cache from the CPU.
Please make sure you are not overclocking anything, if you do, revert back to stock and test the system

Just to be sure, please check AMD for CPU driver updates

No overclocking at all.
We ruled out driver problems.
I might try to underclock the CPU to lower values than the default and see if anything changes.
It's weird though as the crashed aren't related to stress, I've just stressed the computer with Prime95 for an hour and everything was stable. There are times where the computer just reboots when surfing the web or minesweeper.

Try it for a couple of hours, an hour might not be enough.

Have you checked for any dirt/dust in the case?

DarkCowMoo said:

there is some dust, do you think it might cause so much trouble?

Dust can cause so much trouble, you can't imagine.
It is adviced to clean the components once in a while, like once in a month.
