What does it mean when my computer says 'low on virtual memory'?
I get a popup that says Windows is low on virtual memory and then everything slows down or programs crash. I have 256MB of RAM. What is virtual memory and how is it different from regular memory? Can I just make the virtual memory bigger? Or do I need to buy more RAM?

Don't forget about heat. If your computer is shutting down or crashing randomly, open the case and check if the fans are caked with dust. Blow it out with a can of compressed air. Overheating causes a shocking number of 'mystery' problems.

I always tell people: buy a UPS battery backup. A $40 one will protect your PC from power surges and brownouts that slowly kill your hardware. Lost a motherboard to a thunderstorm once. Never again.
Before you do anything drastic, try booting into Safe Mode (tap F8 when the computer starts up). If the problem goes away in Safe Mode it's a software or driver issue, not hardware. That one trick narrows down half of all PC problems.
