I'm running Windows 8.1 on a Lenovo Ideapad Yoga 13 with a Core i5 CPU and 4 GB of RAM that I bought July of 2014. Though I have had a good experience, there's one problem, as you can see from the title.
svchost.exe, the service that bundles DLLs, has been acting up recently. Services tied to it have been eating up more and more RAM, leading to 78% RAM Usage on startup. I suspect it might be a memory leak, and resetting the computer by holding the power button for more than 4 seconds helps, but I want to fix this problem permanently.
I've tried disabling Superfetch and tracking memory usage---it is definitely svchost that is the problem. Does anyone have any idea what I could do to help with this problem? Again, I suspect it might be a memory leak.
EDIT: @FrankThomas 's comment made me notice that, yes, there's a Nuance Communications audio program running on startup, only I have not determined its name. Also, any troubleshooting features I use or Security Center do not raise any alarms.
EDIT: Could it have something to do with increased McAfee Shield usage? That executable has been using lots of RAM as well.
CLARIFICATION: The RAM usage each time I turn on my computer increases, until the computer cannot function properly and I must reset it using the above mentioned method.
