Question about Acer Extensa 4620 Notebook

Booting Error Message No Operating System Found

This Item is a Acer - Extensa 5420
Once the booting page loading, I am receiving the error message :
PXE-E61: Media Test Failure, Check Cable
PXE-M0F: Exiting PXE ROM
Operating System Not Found.
So I figured there was a issue on the Bios screen, I went in and reset to defaults, saved and exited, same error message. So I booted the system up using Linux LiveCD 8.10 and used without installation, When I clicked on '' Install '' to hopefully, find some partitions there was no partitions found. ** BTW I am currently using Windows Vista on the Notebook. **
So I figured I should try using the Windows Vista Recovery CD that I have downloaded from the site, Once loaded, I attempted to REPAIR YOUR COMPUTER, once I clicked on that, there were not System Recovery Options - No drivers found. So I clicked Next, Started with Start up Repair, from there received error message of ''ROOT CAUSE FOUND: A hard Disk could not be found. If a hard disk is installed, it is no responding.'' So from the common sense, and the obvious, looking at me right in the face, there was : A. No hard drive or B. Hard drive was not responding.
So Like anybody, I took apart the bottom of my notebook, where I found the hard disk, removed it, ensured it was clean. placed back in with care, rebooted the notebook....and what do you know.....same error message. I really need help here, and please, be easy and not too much terminology, I'm a noob to all this. BTW I also attempted to contact Acer Tech Support, and like the obvious, they wanted to me to pay for software, that wont even work. So to answer any possible questions about accessing the web, I can do so, with Linux LiveCD 8.10. thats about it, no flash players can be used unfourtently, I have tried downloading a number of anti-virus programs, but just receive, error msg to error msg, and so on, and so forth. Any Suggestions will be taken with all respect and gratidue.
Thanks In Advance,

    How can I tell if it is detected in the BIO?

    What were you doing when the problem started? Were you reinstalling Vista? Installing another operating system on a computer that originally had Vista? Or was the computer working just fine and then one day you turned it on and got this screen?

Make sure that hard drive is detected in BIOS. If not, there is a problem with the hard drive and any attempt to install OS will be futile since there is no hard drive detected. If this basically means you have a busted hard drive, you may need to replace it then to continue with OS installation.

    Please follow the instructions listed below for recovery attempt: (If all else fails please proceed with the instructions on the bottom of the page since like I've said this could possibly mean that you need to replace your hard drive which could be busted already.) Thanks.

    I want to restore my computer to its original settings without

    recovery CDs.

    Note: If your system is the multilingual version, the operating

    system and language you choose when you first turn on the

    system will be the only option for future recovery operations.

    This recovery process helps you restore the C: drive with the original software

    content that is installed when you purchase your notebook. Follow the steps

    below to rebuild your C: drive. (Your C: drive will be reformatted and all data

    will be erased.) It is important to back up all data files before using this option.

    Before performing a restore operation, please check the BIOS settings.

    1 Check to see if Acer disk-to-disk recovery is enabled or not.

    2 Make sure the D2D Recovery setting in Main is Enabled.

    3 Exit the BIOS utility and save changes. The system will reboot.

    Note: To activate the BIOS utility, press during POST.



    To start the recovery process:

    1 Restart the system.

    2 While the Acer logo is showing, press + at the same time to

    enter the recovery process.

    3 Refer to the onscreen instructions to perform system recovery.

    Important! This feature occupies 10 GB in a hidden partition on

    your hard disk.

The BIOS, which handles the initial start up of your computer, cannot find your hard drive and thus cannot boot your operating system (ie, Windows). Open up your computer and confirm the power cable is firmly connected to the hard drive and that the cable that connects the hard drive to the motherboard is firmly secure. If both of these check out, then try downloading this bootable CD on another computer. This CD, among other things, has a few hard drive utilities that will help further diagnose the problem. Finally, if the utilities on this CD are unable to see the hard drive itself, then is may need to be replaced. Try testing with another hard drive or another cable to connect it to the motherboard.

The error PXE-E61: Media test failure usually means the hard diskhas failed or the hard disk needs re-seating or the disk controller is faulty. First - re-seat the harddisk and reboot the computer. If this does not work then reboot and go to theBIOS configuration to see if the BIOS detects the hard drive. If it doesn'tdetect the hard drive then it could be faulty. Next - to determine if thehard drive is faulty, remove the hard drive and insert it into an USB hard drive adapter and connect it to a workingcomputer's USB port. If this computer cannot see itas an external hard drive and you cannot open the various folders and files,this confirms the hard drive is faulty. Then the hard drive needsto be replaced in the computer/laptop, Windows installed and the computer orlaptop's device drivers plus your programs etc. to get a functioningcomputer/laptop again.

You can go to the manufacturers website to check if you have the very latest driver for your webcam. if not, you should be able to download it from there.

Go to control panel, then system properties, then device manager, then hardware. check imaging devices to see if your webcam is recognized.
