I have a custom built pc and its fairly high quality. I built it in december of 2013. Since then it has been working fine. Today March 29 I have been getting numerous BSODs and for different reasons. Most say Memory Management. I tried to run "SFC /Scannow" in cmd admin. It went well until it stopped at 34% it sat there for about 20 mins and then i exited cmd. I have a 120gb kingston ssd, a 1tb wd hard drive and 16 gb G.Skill ripjaws x series ram. I have most things installed on the ssd such as windows 8.1, LoL and Bf4. Things I have installed on the hard drive are manly documents for school and steam. The first BSOD happened while i was watching youtube it said system thread exception not handled. That was in the afternoon, this evening it has been popping up saying Memory Management. I cant open up any programs without the computer crashing . Please help any advice is appreciated. If more info needed just let me know ill do anything to help.
