Hi friends im using win 7 64 bit (oem) for the past few months, i never had this problem, but this problem annoys me. Im havin 4gb of ram. Whenever the system reboots the ram usage is normal but after that it is gradually incresaing and within an hour or so it reaches 3 to 3.5 gb of ram utilization leaving me with only 500 mb of ram to use!!. I used windows resource monitor to find the culprit process but unfortunately the resource monitor shows all the process but nothing mentioned with ram usage of more than a gb. I still cant get where the memory is leaking? Anyone having the same problem or can come up with a solution??
