Return to FAQ List Windows does not detect a new modem I installed. Most modems will install to COM1-4, depending on the modem. If you have a modem that requires COM1 or COM2, you must disable that COM port then try to detect the modem. The memory I received doesn't seem to work. This is often caused by compatibility issues between your computer motherboard and the new memory module.
Some older computers allow only certain maximum memory capacity.
Adding memory might have exceeded the limit. Some proprietary computers may not take standard memory at all. First determine how much memory your computer reads before inserting the new module. Then, remove all the memory modules and insert only the new one to see how much memory the computer registers. You may change the slot the new memory is inserted to see if it makes any difference.
