I got his BSOD since yesterday or the day before. I used whocrashed and bluescreen viewer analyzed the error. On Thu 3/26/2015 11:41:59 PM GMT your computer crashed crash dump file: C:\Windows\Minidump\032615-68531-01.dmp This was probably caused by the following module: wanarp.sys (0xFFFFF800C3019000) Bugcheck code: 0x109 (0xA3A01F592BCD289C, 0xB3B72BDF7E4D16EB, 0xFFFFF800C3019000, 0x19) Error: CRITICAL_STRUCTURE_CORRUPTION file path: C:\Windows\system32\drivers\wanarp.sys product: Microsoft? Windows? Operating System company: Microsoft Corporation description: MS Remote Access and Routing ARP Driver Bug check description: This indicates that the kernel has detected critical kernel code or data corruption. This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules. The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system that cannot be identified at this time. sfc scan, found no error. I also checked spyware. The system still automatically restart with BSOD 'CRITICAL_STRUCTURE_CORRUPTION.' no error code. how to solve this problem ?
