Random BSOD's - No Files Listed Win32k.sys - Ha10kx2k.sys And Ntfs.sys

I've been having a problem with getting BSOD's for a long time now (assuming you don't know, bsod = blue screen of death). For the first couple months I was ok with my computer randomly crashing like this but I started to get tired of so I wrote down the errors I was getting, which were basically all STOP and irql_driver errors, so I figured I would update my drivers and things would start working better. I did that 5 days ago, and now the messages have just changed.

Before, when I used to get them there was either no files listed or three. They were win32k.sys, ha10kx2k.sys and ntfs.sys. The last two traced to either my graphics drivers or my sound drivers so I updated both of those. Now I'm starting to get totally new files, being Klif.sys and bcmwl5.sys. I haven't looked these up yet but will soon. Now, these errors occur at ANYTIME, and I'm not kidding you. Sometimes I come back to my computer after it's been idle for hours and there's a blue screen sitting there (I turned the timed restart off so I could write down the errors). Now, after reading around the internet the only thing I can come to is that my RAM is messed up, but I haven't done a memory check yet (probably should).

Also, if there is any sort of sound playing when I get the BSOD, the sound skips like a record skip and then after 5 seconds starts making the most annoying, high pitched, scratching, static, fuzz noise you could ever hear. Now I've had my computer for 3 years now and these errors started occuring regularly about 8-9 months ago. When I used to get BSOD's infrequently before this period, the sound problem described above still happened, which has led me to believe that my sound card is bad.
