My dell is pathetic and old

The 4400 can support a maximum of 1GB of RAM. It only has two memory slots so in order to achieve 1GB you would need two 512MB cards. This would mean you would have to discard whatever is in the machine now.

The manual on the Dell website says this motherboard has an AGP slot so you could buy a newer AGP video card if you wish.

Here are my thoughts...it looks like this computer came with 256MB of memory and a 1.7GHz Pentium 4 processor. If you're using it for email, office applications, and Internet then buying additional RAM will not be a bad investment. I'm skeptical that a new video card is worth the money unless you're into gaming or CAD in which case you would be better off buying a new system.

I would like you to know that I'm not paid to provide any of these suggestions. It's a strange hobby I know, but I like helping when I can. Many times this type of question will not get a response on this website because there is no "solution" and very often any attempt at helping get's a poor rating. I hope if you've found this information helpful you'll rate this positively. If you have any more questions don't hesitate to ask. Thanks and good luck.
