Hi all,

In our office, we have recently experienced Windows freezing on random computers.
Out of about 50 PCs, approx. 10 PCs repeatedly experienced this freeze and not the others.
Here is what happens...
Users works on Windows, and during lunch, locks their PC and leave the office.
When they return, their PC locks up showing only the desktop.
Sometimes, when you hit ctrl + alt + delete to get the unlock window where you enter your password, it just shows you a grey box sometimes with or without the fields to enter your password and nothing happens.
You have to hard reboot the system to get back to work normally.
For some of these PCs, there is an error prompt stating that windows is low on resources... can't remember exact error.
Has anyone experienced this?

Note: we have checked the power settings etc and they are not set to hibernate or go into standby

Any ideas is greatly appreciated.

Anyone check these systems for possible overheating?

No error messages of any type?

Anyone check Event Viewer for clues?

Systems with insufficient RAM installed...and pagefiles...tend to render the message you mentioned, AFAIK.

Hi hamluis,

Thanks for your reply.
This error has never occurred before we recently upgraded some kaspersky antivirus components (not sure what they are)
Error ID is usually 2000 when we do get something recorded in event viewer.
Also played around with pagefile setting but it did not help.
auto reboot on crash has also never been enabled.
Because we suspected the AV program, we disabled scans and also tried completely uninstalling without much help...
