Random BSODs and no memtest erorrs

Hello. I've been getting random BSODs (0x3B,0x4E,0x1A,0x44,0xD1,0x1E,0xA,0x1000007E,0x50) for several months. Checking RAM with 8 passes memtest86+ (one stick at a time \ 1+1, 1+1+1 and 1+1+1+1) shows no errors. I have only one Kaspersky antivirus. Maybe you can help, because i really don't understand what's happening. :confused: Attaching the necessary info.
