It's been a month since I assembled my new pc with the following specs:- FX8320 R9 270X M5A97 R2.0 SEASONIC ECO 600W Windows 8.1 pro XMS3 4GB*2 The problem is from the first week of my complete build I am getting a Blue screen like this :- http://bit.ly/1mO6mQh which forces my system to restart, and after the restart my PC doesn't recognize my Harddisk, I have to then change the SATA port in which sata cable is plugged in to another, then when i run system boots normally. This problem is really frustrating and now happening frequently. I guess it because the CATALYST DRIVERS of amd gfx card or maybe something else. PLEASE HELP ASAP!!!
