HOW TO REMOVE ASK TOOL BAR FROM YOUR COMPUTER SYSTEM

HOW TO REMOVE ASK TOOL BAR FROM YOUR SYSTEM

How to remove:

The first thing to do is to uninstall the ‘Ask Toolbar’ from the installed programmes.  To do this:

[1] Click ‘Control Panel’ > ‘Uninstall a program; under Programs > locate the ask tool bar installation > Click on it and click to remove.

[2] In some cases, the system will inform you that, some files cannot be deleted, and you should delete it manually.  If so, click on ‘My computer’ > double click on the partition where the O/S is installed, (usually it will be C partition) and double click the ‘Program File’ > locate the folder that has named as “Ask toolbar” or so, right click on it, and select ‘delete’.  The folder itself will go to recycle bin.

[3] Restart the system.  Sometimes, the ask tool bar will still be there at the browser window.  If is, let it be there.  It is inoperative now.

[4] Click on the ‘control panel’ again and click on “Network and Internet”.  Click on “Change your homepage” under internet options.

[5] At the display window appear, you might see some other URL (Usually Ask URL) have been inserted.  Select the whole URL and delete it.  Type in the URL of the browser, you want to be as your home page.  For example, if you wish to select Google as your home page browser, type in  http://www.google.com/  there.  Press ‘Save’ button at the bottom right corner of the display window.  Close all windows and restart your system.  Now your system will restart with Google as the home page.  If you wish to change it with Bing, Yahoo, Mozilla or any other as homepage, type in the URL of that browser as stated above to the display winnow.

[6] If you notice that the Ask toolbar is still at the top of the browser, just point the mouse over it, right click on it, and press delete.  Now all is over.

HP - COMPUTER BIOS BEEP CODES

HP - COMPUTER BIOS BEEP CODES

BIOS BEEP-CODES

What to do when beep codes occur

   Listen to the beeping sound and write down the number of beeps before each pause, if the beeps are long or short, or if the beeps high or low in tone. Once a pattern is determined, use the following beep code table to identify which component might be causing the problem:  Use these codes to help troubleshoot problems related to system start-up or flashing BIOS memory (such as in BIOS upgrades). When troubleshooting further, refer to the section What to do when beep codes occur .
  Four series of beeps indicate a fatal error; that is, a problem exists which prevents the computer from starting. For example, there might be two beeps, a short pause, one beep, a short pause, one beep, a short pause, and then three beeps; this is represented as:

1 short beep and 1 long beep : Memory problem

2 short beeps and 1 long beep (repeats 5 times) : Unable to initialize video or video card required but not installed

3 short beeps and 1 long beep : CPU configuration error or CPU type is not compatible

The following beep codes can occur while restoring, flashing or updating the BIOS:

1short beep : Legacy floppy drive or CD/DVD drive not detected

2short beeps : Floppy diskette or compact disc not detected

3short beeps : Unable to start flashing (such as when missing a utility or BIOS image)

4short beeps : Flashing failed (checksum error, corrupted image, etc.)

5short beeps : BIOS recovery successful

   Perform the following steps to resolve beeping issues. Before starting a task, turn off the computer, and then remove the power cord. After completing a task, replace any covers, reconnect the power cord, turn on the computer, and then listen for a beep code.

* Remove any media from the floppy drives, CD/DVD drives, USB ports, and memory card reader slots, and disconnect all non-essential devices (printers, scanners, external hard drives, and similar).

* Disconnect the mouse and keyboard, and then restart the computer. If the beeping sound stops, repair or replace those devices.

* Hot air can damage internal components! Remove any obstructions that block vents. Clean the cooling vents on the case to remove dust. If cooling fans stop spinning or make strange noises, service the computer.

* Remove the memory cover, and then re-seat all memory modules. If the computer stops beeping, a memory module might not have been fully seated or connected.

  If the computer has multiple memory modules, turn on the computer with only one memory module installed. If the computer stops beeping, the memory module might be defective, or might be the wrong type of memory for the motherboard. Reinsert the memory into the socket to see if a connection was the problem; otherwise replace the module. Repeat this process for all memory modules installed in the computer  If all of the above steps have been tried and the beeping sound still exists, refer to beep code table specific to the motherboard of the computer

Beep codes for American Megatrends, Inc (AMI) bios.

   The following AMI beep codes can occur when there is a problem during the attempt of a normal system start-up. Use these codes to help troubleshoot problems related to system start-up. When troubleshooting further.

1 beep : Memory timing failure

2 beeps :  Memory parity error

3beeps : Memory read or write failure

4, 5, 6, 7 : Fatal errors related to the operation of critical motherboard components - such as the CPU.

8 beeps : Video memory

   AMI beep codes that can occur when attempting to flash or recover the BIOS. You can use these codes to help troubleshoot problems related to system start-up or flashing BIOS memory (such as in BIOS upgrades).

1beep : No media detected

2beeps : ROM file not found in root directory

3beeps : Insert next media volume

4beeps : Flash Programming successful

5beeps : Failure while reading file

7beeps : Flash EPROM not detected

10beeps : Failure while erasing flash memory

11beeps : Flash program error

12beeps : Problem with ROM file size

13beeps : ROM image does not match BIOS requirements

Beep codes for Phoenix BIOS 

   Four series of beeps indicate a fatal error; that is, a problem exists which prevents the computer from starting. For example, there might be two beeps, a short pause, one beep, a short pause, one beep, a short pause, and then three beeps.
