Whenever I am using my pc I always get Interference in AM radio Stations???

Could you please tell me why this is happening and how I can fix it???

You might try a better quality pair of speakers. Better speakers will be
better shielded. My old Altec Lansing speakers did that -- every time a
taxicab went by, I'd hear its radio through my PC's speakers. Getting a $40
pair of LabTec speakers solved the problem.

You need to describe your problem a little further. IE are you listening
to AM stations on your computer? Are you listening to the radio while
using your computer? How far is the radio from the computer? Give more
info.

This is normal (and unavoidable). Computers generate RFI. Go to Google
and look up "Radio Frequency Interference".

The simple answer is that there is always going to be RFI near a computer,
and there is no way to shield it out 100%.

The fix?---Move your radio away from the computer.

The following is from:
http://fusioned.gat.com/Teachers/Curriculum/Curriculum-HTML/T20s-shield.html
"For radio communication, radio-frequency interference can be a big
problem. Just about every electronic circuit that has changing or
oscillating currents in it will radiate electromagnetic radiation, a lot of
it in the range of frequencies that includes radio and TV. Most electronics
products have to be shielded so that they don't interfere with other
devices or disrupt radio and TV communications. This is why so many
electronic products carry a label that shows that the device is approved
for home use by the Federal Communications Commission (FCC). Computers
especially produce a lot of electromagnetic radiation because there are so
many electrons being accelerated in the circuits as the computers do
calculations. If you take a radio which is not tuned to any station and
hold it near to a computer, you will be amazed at how strong the signal is.
You can actually hear it work, just like the CIA tries to hear the
computers working in foreign embassies. You have to try to put a metal
shield box around all the radiating circuits to keep the electromagnetic
radiation inside the computer if possible and if you look inside the
computer, you will see that the designers did just that. Nevertheless, your
computer is a rather good radio transmitter."

This is worse now that so many people are putting plastic
windows in their computers so they can see the wires. These
modified cases are not FCC legal in homes IF anybody
complains about interference.
