Hello!
I need some assistance. My computer, a Windows Vista tends to stall and freeze when I use the internet or computer games. The thing is, my mouse can move but I am unable to click on anyhting and I am forced to reboot the computer.I have looked under the "Event Viewer" and came across the following problem:

<Event xmlns="http://schemas.micro.../events/event">

I always think of heat when I hear a system freezes. What are your temps? Is the system free of heat trapping dust? Are all vents clean and fans spinning?

Other causes can be a failing power supply, failing RAM, or failing motherboard often due to leaky (and therefore failed or failing) capacitors (more of a problem with older systems).
