It's time to get upgraded - XP goes end of life (no more security updates) in just about five months (April 9l, 2014).

I'd love to update to newer, but again, no money. I [ADMIN NOTE: Substitute characters deleted as per TOU] for broke poor. No job. I'd love get an IT job but I have no college behind it. I've only got the "jimmy rigging" know-how as people call it.

Still get that beeping sound and still have these as problems: PCI bus 3, device 1, function 3 PCI\VEN_1180&DEV_0592&SUBSYS_01BD1028&REV_0A\4&2FE911E8&0&0BF0 PCI

If it's beeping, check for a stuck key.

You need to install your card reader and audio drivers.

Okay your model no is an Inspiron 6400.

As mentioned it seems that you might have a stuck key. Please refer to the Service Manual:

http://ftp.dell.com/Manuals/Common/inspiron-6400x_service%20manual_en-us.pdf

Follow the instructions to remove the keyboard. Once you have removed the keyboard clean any dust off the ribbon cable and reseat the keyboard. This often alleviates the problem of stuck keys caused by a loose connection to the mainboard.

However it is worthwhile for you to run full system diagnostics as I suspect there might be some hardware issues. See Windows Reinstallation Guide/F12 Preboot Diagnostics (page 374):

If the hardware diagnostics pass then the suggestion would be to perform a clean install of Windows. In general I would not recommend reinstallation of Windows XP as it is reaching end of life however as you are tight in funds you may need to do so. Just be careful for more information see:

As you are interested in working with IT you may want to build up some experience with Windows 8.1, in this case you can install the 90 day of the enterprize trial, this system will only likely take the 32 bit version:

Windows 7 32 bit drivers are available here:

You may install these (with the exception to OS Updates and System Utilities in Windows 8.1.

For installation of Windows XP, 7 or 8.1 on this system see Windows Reinstallation Guide/A Clean Install of Windows XP/7/8.1:

http://philipyip.wordpress.com/dell-community-forums/

This will instruct you through the installation process. Keep in mind that this system is a media direct system and media direct partitions should be set up (Step 7b) before installing the OS.
