Did you replace them or what exactly did you do?
Months ago i had 16gb (4x 4gb) on my system, and started to experience random BSOD that were related to my ram, did some test and 1 of the sticks apparently had a problem, so i took 8gb out.
Months go by and i start to experience this high disk peak, but as i said there were no problems detected on RAM, still i took the chance and replaced with the other 8gb i had taken out before.
I had the spotlight issue and thought that changing the ram didn't fix it and that could have been the PSU or GPU, but after fixing the spotlight with powershell everything has been fine.
That's why i didn't reply back, since my last post i haven't had high peaks, maybe 1 or 2 after a system restart but PC doesn't freeze for moments and disk comes back to normal.
I can't test the PSU because i don't have the tools to do so.
Lcore is updated, installed it directly from logitech, unistalled PubMonitor but shouldn't be the issue, since the problem was present 2 times right after installing windows in a formated partition.
Right now im not sure if the problem has been fixed for some reason, but i haven't experienced it for days.
Thanks for your help dmccoyks
