I have intel i3 2120 and my processor is DL-ipmsb-h61 http://support.hp.com/us-en/document/c03069802
i recently bought a 8 gb 1600mhz ram
now every time i play a game or install anything i get a blue screen error
is there a solution to this problem
Based on the motherboard model, it seems the memory can be causing the problem. The memory you have is 1600MHz and the motherboard can handle up to 1333MHz so this could be the problem.
Also, it is important to say that the processor can handle up to 1333MHz so this can definitely affect the system performance.
Please use a compatible memory with the processor and this should resolve the problem.
