Hey, im just built a new pc and installed and updated all drivers properly. But it keeps crushing and most common bsod is "Ntfs_File_System" and "Service_Exception_Not_Handled". I searched almost all of similar forum post and I still get bsod's. İ have tried to run Memtest86and it couldnt find any error in rams. Sometimes data corruption occured in my several files and I have ran HD TUNE to find any bad sector but it was ok too. I have done all I can and it still crushes 2-3 times a day. About system: Windows 8.1 Asus p9x79 motherboard Asus Gtx770o.c. graphic card Intel i74820k processor I have got cooler master gx bronze 750W p.s. I couldnt attach my minidump files because its so big so I have uploaded them: http://www.filedropper.com/minidump Thanks for help..
