Hello, I have reason to believe that my motherboard Asus P8Z68-V LX is faulty. The processor is an Intel i5-2500k (Sockel LGA1155), while I have the Nvidia Gforce GTX560. I bought and built the system in early 2012 and now the mainboard doesn't work all the time. As I don't need top-notch performance, I don't plan on buying a new mainboard, CPU, GPU and RAM but would indeed prefer replacing only the defectuous mainboard. However, I cannot find the same (or other P8Z68) mainboards for not too expensive in any of the better known online hardware shops. What would you suggest as a resolution to my problem?
