Question about HP Compaq dc7100 PC Desktop

HP DC 7100 tower PC

Robert, thanks so much for answering.
This is the tower chassis as opposed to the other two slimline chassis.
I have gotten as far as downloading the manual from the internet, which has diagrams and instructions on how to install disk drives, CD's and all kinds of other stuff but not a word about modems.
Only in the 'troubleshooting' section is there a mention of the Internet, and their advice is simply, 're-install the modem' , with no diagram.
My thought is, this computer arrived with no modem and I have to buy and install one.
There is a section on "expansion ports" which I take to be the 7 blank metal socket covers on the back of the computer.
Inside the computer, behind the bottom three, is empty space.
Behind the top port is a black thin socket, apx 4" long, says PC1EX16,
below it, a very short 1" black socket PC1EX
The 3rd and 4th sockets are both cream colored, same length as the top
and numbered PC11 and PC12. Would one of these take a modem?
There are many other smaller, color coded square sockets, below and to the left of the memory cards, but I have no diagram of this part of the computer to figure out their purpose.
I use a free dial-up internet service (MetConnect), and have only one ordinary, not DSL, phone line and plug my regular phone into the computer next to the plug for the line from the wall.
There is nothing like a double phone plug on the outside of this new computer, only a phone jack with the double-tv symbol, which I take to be for big offices with their own networks.
While my old computer came with a modem, I found the service improved when I replaced it with one from US Robotics 3095 56K internal fax modem.
Are dial-up modems universal, or do I have to get one specifically for this model computer?
I have yet to power up this computer, because I know it will ask me questions and I want to get my story straight first. Thanks in advance for any guidance.

    I did just what you said, and it worked perfectly! Thanks so much!! I took the old modem out of the old computer, and plugged it into the new one, instead of hunting around to buy new equipment. I'm on the internet with it now!

    I think I better sign up for your premium service anyway. I sense

    problems in the areas of using a second monitor/video cards, as well as transferring files.

    Also, I'm wondering what I can use all these extra USB ports for.

You should be able to uninstall the modem from your old computer and put it in a pci slot of your new one
... same location as your old computer. you may need to install a driver for it but then you may still have the installation disk.
we will tackle that when you have swapped the modem over. incidentally that other connector was probably a network card... the connector is wider then a phone plug tho it looks the same.

    Thanks for rating the solution.

    USB ports have so many functions. basically it super simplifies plug and play.

    Go to a computer shop or browse the net to find all the items you can use with usb.

    I would suggest picking up a usb flash drive as they come in quite handy and you can use them as a quick back up for pictures and other files. Just plug one into a usb port and drag and drop the files you wish to save (space permitting of course)

I can not start HP compaq dc 7100 CMT. starting four beep

Hello there, this means the machine has an internal hardware failure. 4 beeps almost always indicates the memory (RAM) has gone bad in the machine. If you are unsure of how to put new ram in the machine yourself you are going to need to contact a local service person to do this, it should not be too expensive. If you need help locating someone in your area please respond to this answer with your zip code and I will find someone for you.

Please make sure you rate my answer 4 thumbs up, it is extremely important to me. I would be forever grateful if you could do so. If you need more help on this question please just respond to my answer here and I will get right back to you.

HP Slimline desktop shuts down on it own without warning

you need to take off the fan to the cpu and blow out all the dust and dirt. removing the cover for better cooling is actually a bad thing to do.... with the cover on the fans will move air thru the computer to cool it... with no cover the air does not circulate for best cooling.

Toshiba Portege 7100 SlimLine Notebook

they should be the same the close number just means that they revised something... most laptops have builtin wi fi but if it doesnt just buy a cheapie usb or pc slot card! I would NOT reccomend that you install windows vista on your pc.....there are still yet too many problems with them and you will have A VERY hard time getting drivers that are compatible

as far as the rest of the specs... ask the seller! they should know or see if it says on the ebay auction page
