Please check the MB here and confirm that it is the same as yours.
You have your Ram in slots 1 - 2 and 3, if the MB at the link that I included above is the same as yours then the Ram should be in slots 1 - 3 and 5, this because the Ram is the triple channel type, not having it in the correct slots would cause stability issues.
Two other things that I noted from the Speecy report, 1: You have no AV protection, if our work here does not resolve the issue I will refer you to the GTG malware forums, if our work here does resolve the issue I will refer you to the GTG malware forums self help guide. 2: The amount of free storage space on your HDD is well below the safety limit and has most likely led to data corruption on the drive - would I be correct in that the fresh installation of the OS was to the Intel SSD.
