First thing is test your RAM.

well i went into my BIOS and my active temp is 158 degress F, could this be the problem, i havent put a non-stock heat sink on my CPU and i didnt buy any fans when i got the computer just got the one that came with the case

Cool your case first before you replace your stock heatsink/fan unless the stock fan is not running properly. May want to try dusting it and the heatsink out as well.
