Hey guys, I'm facing various problems with my new PC and very often get BSODs in Windows 8.1. That's why I decided to reinstall Windows completely after formating the SSD. After each important step I safed a Windows backup and started Windows verifier. I recognized installing the newest Nvidia driver always crashes the system (I reloaded an older backup and installed an older driver). But yesterday evening and also today I again got BSODs (see minidumps below). WhoCrashed always says "This was probably caused by the following module: ntoskrnl.exe (nt+0x14DCA0) " ... But before reinstalling Win 8.1 I also got different BSODs like MEMORY_MANAGEMENT error, SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION, KERNEL_SECURITY_CHECK error and some others. The funny thing is sometimes I can reboot my system with verifier without problems, but then suddenly again the BSODs I described and included below. I thought about a faulty RAM, but memtest found no errors after 7 passes. ***edit: Again very confusing behavior after installing ESET Smart Security. When I rebooted with verifier for the first time after installing ESET the system was frozen (see added minidump). Then it rebootet with verifier on and it was successful. I don't understand that shit :X Any ideas?
