When i check rsource monitor after starting the computer i see hard faults on any program(s) runing at the time. Sometimes the total number comes up to 400hardfaults/sec and the total RAM usage is about 15% with 6gb of RAM installed. wHAT COULD BE RESPONSIBLE FOR THIS?
That is perfectly normal, and nothing to worry about.
In previous versions of Windows, these were known as page faults and these occurred when the address in memory of part of a program is no longer in main memory, but has been instead swapped out to the paging file, making the system go looking for it on the hard disk. Note that regardless of the amount of memory installed, Windows is designed to use a paging file and, although you can adjust the size of, or even disable, this file it is recommended that you leave it alone and allow the system to manage it. Some programs are designed with a paging file in mind, and will not run if one isn't present.
