I am using Firefox and for quite a while (actually since I have had this computer), something was hogging all the memory.I looked in the Resource Monitor and there is a program called svchost.exe that was the problem.
At times it is using over a gigabyte of memory.
I have been ending this process with no problems for a while - the system sort of does a reset, but after a few minutes, everything is working normally.
Can this cause any long term problems?
