No, I just HDD Windows 7 Ultimate 64bit. I had damaged sectors on the HDD, but I with the software "Hard Disk Sentinel" fixed the bad sectors. After the repair everything was fine until now, the last time removed me restore points. The disc's no I could not find malware, harmful software or else. The system runs fine, also runs fine. Sometimes when I turn the computer requires if I start the computer in normal mode. When you run it in normal mode, I see no problem, I just disappear all the restore points. I do not know if this behavior can be set in the settings somehow. In the "C" I have enough space. To the "D" I redirected all the file folders that remain in the "C". More than half of my HDD capacity, occupies an area of "E", we use the regular system backup image. Usually my work is the repair of damaged bootmgr or similar defects, but I have yet to meet a similar anomaly that myself or something in the system, removed the restore points...
