After using the laptop for some hours, I get a popup message that says "Out of virtual memory : Your system is low on virtual memory. To ensure that Windows runs properly, increase the size of your virtual memory paging file. For more information, see Help."
This is a Windows 7 laptop, 8GB memory, 64 bit.
After the popup shows up, the computer display is all messed up and the computer does not respond to most commands. If right click on the taskbar, a popup comes up, but there are no texts on the popup. Also there are no texts shown on the start menu and the start menu is not completely/properly displayed. This goes on till I restart.
I looked in the event viewer and saw event IDs 26 and 2004.
