You can find out the CPU and installed RAM if you open windows explorer, right click My Computer and click Properties. It'll tell you the processor, speed and installed RAM. It's relatively simple to replace a keyboard on a laptop. You'll want to shut off the power and disconnect from the power supply (and pull the battery even though you think it's dead). Then you'll probably need to lay the display flat. At that point, you should be able to pop out a flat piece that sits between the display and keyboard. The keyboard should then come out easily (there may be a couple of screws). There's a ribbon cable connecting it to the motherboard. Pull that out, put in the old one, put the flat thing back and you're ready to go. But the USB keyboard will probably be cheaper and easier to install if you want to go that route.

The computer boots normally with the original ram module. When I put in either of the new modules-I get the error message through the blue screen. The specs above are from the 'crucial' scanner, but I bought the RAM elsewhere online. The Dell 4300S is an older system--bought in 2005. I have a new laptop, but wanted to upgrade the memory in the desktop-because I want to keep it as a backup. It still works great-just slow. I like to keep 2 systems because you never know when you might have a problem with one and need to research or download with the other to fix it. ravencajun Thanks for the link to Belarc. I ran the Belarc software- but it seems like the RAM I purchased should be compatible. Of course, I could have missed something. (are you sure the ram you got is non Ecc?) No I'm not sure-could you explain this? This may be the problem. And THANKS AGAIN to all of you for your help.

a good guide to follow for any pc Help! My computer is slow! one problem with Dell is they put a LOT of crud on their computers that is not needed have you removed all the excess baggage? What AV program are you using? if one like Norton or McAfee they are very large and can slow down a pc. following that above guide and using a start up monitor to see what is starting up and limiting those items can help a lot. The pcdecrapifier tool was specifically originally created for Dell products to help users get rid of the fluff. PC Decrapifier That AMD Turion processor should be plenty fast, I love AMD products they are excellent.
