How long since you cleaned out the dust bunnies inside the case ?
My Dell Dimension 2300 is only 4 years old. Everything was running fine and then one day after restarting the computer, it just shuts down automatically between 5-7 minutes after it starts up. Within that time, I've tried clicking on Internet Explorer but the computer just freezes up and then will shut down. Won't stay on long enough for a virus scan. It has the Windows XP operating system.
Does anyone know what might be wrong?? Can I get it fixed and not have to buy a new hard drive? PLEASE HELP!!!
