My Windows 7 laptop of 1.5 years old seems to be leaking memory. After it boots and I log in and it reaches steady state, the memory consumed is usually about 1.5 GB. My laptop has 4 GB RAM. After steady state, I start outlook, chrome, Xemacs, acrobat reader, a few putty sessions. I notice that within 1 or 2 days, the memory consumption goes to 3+ GB. After it crosses 3 GB, chrome tabs start crashing and Chrome itself starts crashing. I even get a message from the OS saying to free up memory by closing applications. Overall, the system becomes slow and unstable and forcing me to reboot. Sometimes, I have observed that even after I have quit all the above applications, the Task Manager shows that the Memory consumed is at ~3 GB.
From the Task Manager (I also have pstools from microsoft) and was unable to figure out where all the memory is being consumed -- Kernel ?
This being 2012, I prefer not to reboot my laptop for 1-2 weeks at the minimum since shutting down and reboot takes a lot of time.
What can I do to figure out if this is a Virus issue or a genuine OS issue ?
Pagination file : I earlier had a 4 GB pagination file but have reduced it recently to 500 MB. The memory leak problem hasn't shown a difference irrespective of the pagination file size.
