In this instant the system is behaving as if there is no available memory: I am unable to open any applications (Adobe Acrobat Reader, for example), or in another example, unable to create a new email in Outlook or a new tab in Firefox.
At times I am unable to open a folder window in My Computer until I close some other open application (any open application, apparently to free up system memory).
When I reboot the system will function normally for some period of time, possibly one day, possibly six then the problem will return until the next reboot.
The system is as free from viruses, worms, trojans and other exploits as it can be, as detected by Norton Antivirus, the most recent version of MS Antispyware (or whatever they are calling it these days), Hijack this, and various online scanners.
It appears that the system is short on -some- system resource, but I have no idea -which- resource it might be.
