Hello and thanks for your time. I've got a relatively out of date computer that runs most current games with little trouble. Recently ive been experiencing freezing while running some high memory use applications. ( well higher than it would be normally) It has occurred 3 times now over the past few weeks. Twice while messing around on world of warcraft, once while playing modern warfare 2. This computer is using the following: vista service pack 2 32 bit,intel core 2 duo 2.33 ghz, 2 gigs of ram, nvidia 8800 gts, I am not tremendously computer literate so have patience for my ignorance regarding certain issues.
