My first thought is you have a memory problem. Go to control panel and find system to see the details of the computer.No not your brain the computer. If it is old and you have low memory to hold the open programs and to run EQ. Which uses a ton of memory when you are designing. Add malware to the mix and it will continue to shut down on you! First find out how much memory you have on the computer. Second find Super Anti Spyware free program and run it several times. Also keep your anti virus updated. I can get hubby to give me the free ones he uses. Then if all else fails invest in a new computer.
