COM3 not installed

I formatted my hard drive and re-installed all the programs. I have an internal modem and it is automatically detected and installed on the boot up, however it is installed on COM3 and this COM is not installed when I check in the device manager.

How do I install this COM3 or do I have to change the modem to COM1, in which case, how do I do that?

Internal modems needed from unused port (in your case Com3) to work with old communication programs , if you want to use Com1 you must disable it from the BIOS (not recommended)and asign it to internal modem (from the aplet in Control Panel).

Is this internal modem a Winmodem?  If so, it should be assigning itself to COM5.
Remove the modem from Windows and shut down.  Remove it from your system and start it back up without a modem.  Now shut down and install it again.  Does it detect and set it up properly?

Com 3 is a "virtual" com port in that it doesn't exist naturally and won't appear in device manager on a normal windows installation with com 1 and com 2 enabled in the bios.

You can use add new hardware in the control panel to add a new com port. If you already have com 1 and 2 then remember that com 3 will use IRQ 4 (same IRQ that com 1 uses by default - which could be a problem if you have a serial mouse in com 1. You'll have to move that to com 2. But even then some modem installations won't see the port when you get the screen to choose a com port.

Some modem installations automatically create the virtual com port and configure the modem to use it. If that hasn't happened then first delete all items in your device manager that show up with a yellow exclamation mark (especially the ones under "other devices"), including your modem itself. Then add the com port 3 and restart the PC. Remember to choose "cancel" when Windows picks up the modem as a Plug n "Pray". Once inside windows then install your modem drivers or detect the modem.

As already suggested you may need to disable a com port in the BIOS first but I assume that when you re-installed windows you didn't change any bios settings.

COM3 doesn't need to be "virtual". If an I/O register is detected at the address assigned to third serial port, this will be the COM3. Some internal modems are indeed equipped with serial port hardware; if you're lucky they can be set to an unused I/O address... "Winmodems" are of course something else.

I disagree with delete.
This was probably removed physically and within Windows and redetected properly.
