Alright I've noticed couple of anomalies in your system logs:
1. FTDisk Error:
It is Windows fault tolerance driver, which provides the mechanisms for redundant data storage, volume management, and dynamic data recovery. FtDisk works between the physical disk drivers and the file system drivers, and works with all the supported files systems (FAT, HPFS, and NTFS). NTFS is the only file system with built-in data recovery mechanisms.
If FtDisk finds a bad sector on a fault tolerant volume, and the physical disk supports spare sectors, and has spare sectors available, FtDisk replaces the sector. This is true for all tree supported file systems (FAT, HPFS, and NTFS); the file system remains unaware of this mechanism.
Error related to NTFS on your HDD started around 17/7 according to that log, and are regularly appearing ever since.
Please go to your hard drive manufacturer's site, and download diagnostic tool for your HDD model, and check your HDD with it thoroughly.
2. TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts. This isn't causing any stability issue, it is just telling that you are trying open more concurrent sessions than allowed by default.
