Ever since the 14th August I have been having my hard drive reset whilst playing video games - when something intensive has to load then sometimes the entire computer freezes for about 30 seconds and I get a warning in Event Viewer that "Reset to device, \Device\RaidPort0, was issued." (Event ID 129). After googling dozens of forums about other users experiencing this issue I have found no working solution.
I have tried various solutions such as disabling PCI Express Link Power Management and setting AHCI Link Power Management to active. The drive is a Samsung SSD 840, which I have had for a few months now. These issues have only ever occurred after the Windows 10 upgrade. The SSD is configured correctly (e.g. using AHCI Mode, plugged into a SATA 6Gb/s slot).
This issue (according to Event Viewer) has happened 37 times since the 14th August. Things that were installed on that date were the latest Nvidia drivers for my graphics card so I had a feeling that might be the issue. So I reinstalled the drivers but the issue happened again today. The only other event shown to be happening at the same time is that apparently one second after the hard drive reset the "Software Protection Service" was started but I'm not sure if this is relevant.
