Pcmcia is flashing and no sound out of our receiver

Booting from CDROM might be the easiest way to have the OS installed. If the BIOS supports booting with USB flash drive, you can use a bootable OS USB flash drive. Making one bootable USB flash drive may be a little complicated if you don't have a CD of the operating system.

Otherwise you have options of those miniSD card or PCMCIA cards with the size of your credit card which can be used as an extension of your input devices or storage devices if you can find those ports on your laptop. PCMCIA cards are developed through time and having quite a bit versions and standards. I suggest you to contact Dell to make sure that laptop support certain types of PCMCIA card.

It is a possibility that you are getting feedback from a device that is near by. Possibly a cell phone or other device. I would recommend moving the computer to a different location and removing all electronic devices from beside the computer, then reconnecting speakers.

It is also possible that you have a bad sound card. If that is the case, you will need to purchase another sound card and replace the old one. I have included instructions on how to replace your sound card below:

Here is a site where you can purchase the sound card you may be in need of:

There are other sites such as Ebay where you can also purchase the sound card. The type of sound card you need is a PCMCIA Sound Card for an Acer Laptop.

Here are instructions on how to install a new sound card:

Installing a PCMCIA Sound Card in Your Acer Laptop
1. Step 1 Locate the PCMCIA card slot on your computer. On an Acer laptop, the slot may be either on the left or the right side of the laptop.
   
2. Step 2 Remove the PCMCIA card cover by pressing the "Eject" button and pulling the cover out.
   
3. Step 3 Insert your PCMCIA sound card with the connectors facing in and the upper label facing up. Some PCMCIA cards will have an arrow to make it easier to orient the card correctly.
   
4. Step 4 Press the PCMCIA card gently into place.
   
5. Step 5 Windows will recognize the PCMCIA card and search for the needed software.
   
6. Step 6 If your sound card came with an installation CD, insert it in the CD slot and follow the instructions to install applications and utilities for use with your new sound card.
   Installing a USB Sound Card in Your Acer Laptop
7. Step 1 Turn the computer on.
   
8. Step 2 Plug the USB sound card into the appropriate USB plug on your laptop.
   
9. Step 3 Wait for the computer to recognize the new USB device.
   
10. Step 4 Insert the sound card manufacturer's CD if prompted to do so.
    

If a sound card is not the issue, then you possibly have circuitry issues on your laptop motherboard. For this issue, you may need to consult a certified technician at your local computer repair shop.

(If you are not a professional or are used to opening your laptop, I would recommend taking it to a local computer repair shop for a certified technician to look at this issue. Do bare in mind if you have a warranty, opening your laptop and not being a certified professional would void any warranty agreement you have with your manufacturer)

pcmcia card is same as lan card( also known as nic card, ethernet card) of your pc. pcmcia card is used in lap tops.

Look on EBay for one. You might find one on there. You might be able to get away with using a 64mb compact flash card with a pcmcia adaptor as well as a SD card. It can't be any bigger than 64 mbs.

Search under Ricoh memory cards.

They use PCMCIA as well. If you don't have a notebook with pcmcia you will have to get an adapter card for PCI use on a desktop.
