Hi, I'm trying to fix my mom's laptop and every time I think I am done, something new comes up. This time I have noticed that when I use it, the hdd lamp lights up and it freezes for a few seconds. Which is frustrating given that it is HP ProBook6560b and that it should work smoothly. There is no demanding software on it, just mozilla, skype... I have tried looking in the resource monitor and noticed that in the drive section it often says 100% highest active time. I added a snapshot of that. And it seemed to correspond with when it lagged. I also found a bunch of MsMpEng.exe was the most consuming file there, so I did what was listed on a forum as a likely solution and added that file to exceptions list in Microsoft Security Essentials. It is no longer listed a bunch of times in resource monitor, just once, but the problem persists. I also disabled prefetch in the registry, which seems to have made it a bit better, but the problem persists. I am including a NFO file from sysinfo an hope tat you guys can help me out. Best of luck!
