BSOD - How to fix?

[Syntrax]

Hey Guys,

Lately I've been getting a BSOD with the error Driver_Overran_Stack_Buffer. Im kind of worried about this and wonder how I could fix this since I don't know much about these things. I have read the topic you have to read first before posting a topic like this, but in my C:\windows\minidump there are no .dmp files. My pc hasn't been made by a certain manufacturer but is self-built, the specs are as following:
Motherboard: ASUS A85XM-A
CPU: AMD A8-6600K APU
Sound Card: Asus Xonar DG Audio device
RAM: 12 GB
Power Supply: Not sure about this one, but think it was 500W Cooler master
Graphics Card: AMD Radeon HD 7800 Series
I hope you can find me a solution, and thanks already.
