Try resetting your bios. INSTRUCTIONS (http://www.wikihow.com/Reset-Your-BIOS)

Does it happen with all disks? Is it just a cd rom or is it a cd burner?

It's probably a faulty cd rom drive. That's just a guess as you have given very little information to work with.

How many ata sockets does your motherboard have?

Ok, can you describe what type of drives they are (ata or sata) and exactly how they are connected? Same with your hard drive(s).

Might be an idea to get a new data cable to try out, they cost very little.

I don't remember you saying they don't show up in the bios, that's a whole new ball game.
You need to check the data cable to see if it is loose at all. Same with the power cables.
Can you also...

It's just a possibility that Mbam may pick up something.

I agree about AVG, I used it for quite some time before finding out it was no longer all that effective.

AVG isn't as good as it used to be unfortunately.

Download Malwarebytes' Anti-Malware (http://www.majorgeeks.com/Malwarebyt...are_d5756.html) to your desktop.

* Double-click mbam-setup.exe and...

I doubt that it is the motherboard on it's way out. Usually, when they go, they go.

What protective software do you have and have you scanned with it recently?

N13219 D33005 comes up with nothing on the Asus site. Is there anything else printed on it?
What does windows call it?
What windows version have you got?

Is it a plug in card or is is built into your motherboard?

Is there also a problem with the time and date being incorrect?

It sound like drivers and software have been either disabled or corrupted. You need to go to the HP Compaq site and update all drivers and software.

That's why I have asked if it has worked properly before now.

Frank, has the drive been working properly before now? If so, I don't see how a jumper setting could be the cause of your problem.

Have a look in Manage to see if is assigned a drive letter.

To do this, right click on your "My Computer" then select "Manage" from the list. The select "Storage" then "Disk Management(local)"....

Cool! :)

A good Google is what you need to do.

64 bit version of what? Both XP and Vista are available in 64bit versions.

The best thing to do is google for 64 bit drivers and get hardware that you can find drivers for.

That download also contains the driver they say.

What actually happens when you connect it and what windows version do you have?
There should have been a cd that came with it with the software / driver needed, do you have that?

A very quick Google came up with the answer - http://olympus.co.uk/consumer/2581_vn-4100pc.htm

If you have windows live messenger, run through the audio / video setup and it should over-ride all other software and get your mic going.

No problem! A few seconds with Google is all it took.

Compaq is now owned by HP. Go here - http://welcome.hp.com/country/us/en/support.html and enter the information they ask for.
Your laptop will have all the information they want on it somewhere.

What laptop is it? What version of windows is on it? We can only work with the information you give us.
