Various BSOD while doing pretty much anything, mainly memory related

[ArizonaTea]

Hey guys so after one year of perfect running my custom build pc have started bsod on me pretty frequently. I get mainly memory_management and irql_not_less_or_equal. I have tried repairing Windows with the installation CD but I get a bsod every time. If someone could give me a hint about what is causing all this I'd be really glad.

Thank you
