Guess what? I went to Wal Mart tonight to pickup some food and other essentials, the weather is going to be nasty the next 3+ days. I had to pick up some computer screen cleaner, as in another post I was advised not to use alcohol to clean with. When I was looking for the cleaner, I passed by the desktops. The exact same make & model of mine was there. You know what else? It had 4GB RAM & a 500GB hard drive. Mine is 2GB RAM & a 320GB hard drive. You know what else? It was $20 less at Wal Mart than I paid straight from the factory. I wished I never saw that computer. But now I know for sure that it will hold 4GB. So that question is behind me, and as soon as I can, I'll do the RAM upgrade. But you would think that a 64 bit computer requires 4GB, because I've read it here and on several other forums and in tech articles. I read lots of that stuff. It runs fine for now, but when the shift to more and more 64 bit programs becomes the norm, the PC won't perform to it's potential. But one thing for sure, I'll never buy direct from the factory again. They emailed me the promo for the PC, and I bit. The price was good, I researched and couldn't find one with all of the built in features for the money, so I bought it. However, I overlooked or didn't see that it was 64 bit. But the computer is still a good one, the best that I've had, and by far the best OS that I've ever ran. And I've installed RAM before, so I've just decided to do just that. But in 5 or 10 years or however long this PC lasts, I'll be sure to pay attention to the specs a lot more. This thread is solved.
