Hi!, 3 days ago I built my very first PC, using this build (http://pcpartpicker.com/p/15tmJ) it was all running great but then yesterday I started encountering multiple BSODs that says Memory_Mangement(this is the most common one), IRQL_Not_less_or_EQUAL(only appeared once) and Page fault in non paged area(only appeared once.) What I did was I reformatted my HDD and while installing the OS, during the "windows is expanding" part to be exact I keep on encountering a problem stating that the files are corrupt or missing. Then I did some research and I found out that Removing one of the RAM sticks would do the trick and it actually did. Right after the installation of OS, I put the second stick back on and it started having BSODs to the point that I can only use my pc for like 5 mins at the most before the BSOD occur. So I removed one of the sticks again and to my surprise it aint having BSOD and as of now its been running for about an hour or so without any problem. I am sorry if this is a stupid question but which one do you guys think is the problem, my mobo's RAM slot or the actual RAM card? pls help me. any help is greatly appreciated and thank you in advance!
