Flash said: You mentioned DDR on the graphics FX5200 PCI and SDRAM for the 256 module. Without concern to pride, I need to ask, what's the difference between the two and how do they work?
Absolutely! I'd be happy to explain.
All computers have some amount of memory devoted to running graphics. In a computer with an integrated graphics adapter (such as how your computer is working now), a small amount of system RAM (the regular SDRAM in your case) is sectioned off and devoted to graphics; probably somewhere between 8 and 32MB in your case. This memory is unavailable to the computer to use for anything but graphics. The rest of the system RAM is for all other computer functions, like running windows and applications.
When you add a dedicated graphics board, you significantly increase graphics performance because modern day graphics adapters have dedicated graphics memory directly on the card separate from the system memory. It doesn't matter what kind of memory is on the card because the card has its own memory controller to manage it. In that card's case, it's DDR RAM. Other cards may have GDDR, GDDR2, or GDDR3 (on the most expensive models, the difference being speed and price). The more memory built on to the card, the more complex 3D models it can render, and the more detail it can show on the screen at one time. Best of all, when you have a dedicated graphics board, all the regular computer memory becomes useable for other things.
Keep in mind, adding a new graphics card isn't always a plug and play kind of operation. To do this right, you'll need to get into the computer's BIOS (more on what that means when you get ready to install the card), to disable the onboard graphics adapter. It's not too difficult, but you need to be careful when changing BIOS settings. You'll also need to install new display drivers to run the card, but fortunately, that's the easy part. :-)
As far as your new hard drive goes, make sure it's compatible with your PC. You'll see SATA and PATA IDE hard drives. Your computer doesn't have SATA support, so you'll need a PATA IDE drive. Larry is correct that ghosting a new hard drive is one way to completely transfer all the data (windows, installed applications, and all) to the new drive. It takes special software to do it, and can be a bit tricky for the novice user, but not impossible. Your other option is to install the new drive as a secondary, and just use it for storage. Or, take this opportuninity to give Windows a fresh install, which will take more time since you have to reinstall all your applications again, but will make sure you're starting from a fresh point free of viruses and spyware. The right choice depends on how old the existing drive is, what the size of it is, and how much time you have to invest in getting everything running again.
I'm loving this discussion! Feel free to follow up with additional questions.
