Electronic Projector display no signal?

  May 31, 2011    

Scenario:
I set up computer in our conference room. I plug the electronic projector
cable to the dedicated video card. I turn on the electronic projector first
and then the computer. After a few minutes, the electronic projector
did not display anything even the booting up of the computer. It only display
no signal. I check the cables and restart the computer again. But it only
display no signal. It sounds like there is a problem, its either the computer
or the electronic projector. This is the procedure I made.

1. I check the electronic projector if it search automatically the computer
    that was connected to it. I press the search  button on it then restart
    again the computer. But nothing happen.

2. I think that there might be a problem in the computer. I suspected
    that there is a problem in my dedicated video card. That's why
    I open up the case of the computer and check the video card.
    I notice that there is a blown capacitor on it. I removed the
    video card and plug the vga cable into the built in vga adapter
   of the motherboard. I turn on the computer and now it boots up
   normally. The electronic projector is display the Windows operating
   system.

  Look at the picture below. This is the capacitor I have seen in my
  video card.

Troubleshooting loop boot problems

  May 25, 2011    

What is loop boot?

Loop boot is a term used when a computer keeps on restarting automatically.
You will notice that when you turn on your computer and Windows logo appear
but does not continue to load the operating system but instead it automatically
restarting. It will not stop to restart unless you turn off the computer.

Possible causes of Loop Boot

There are lots of possible causes of loop boot. Here are some list that
I was already encountered.

Video Card
Defective video card is the possible caused of loop boot. If your desktop
computer have dedicated video card, try to remove it and plug the vga
cable from your monitor into the built in vga adabter. Your computer will
use the built in vga graphics of thethe motherboard and your computer
will work normally.

Lan Card
Normally desktop computer have built in LAN adapter on its motherboard
but some pc use lan card for some purposes. If the LAN card is defective
it also make your to restart automatically.Remove your LAN card and turn
on your computer.

Corrupted Operating System
Possible reason was the Windows operating system is corrupted. To fix
this problem, you have to reinstall the operating system.
Hard disk problem
Loop boot could be caused by your hard disk. If your hard disk have
bad sector ,files within the hard disk would be corrupted. Fix this problem
by using your Windows operating system installer or you can make that
hard disk to be slave in other computer and perform checkdisk utility.

Memory Card
A defective memory card can cause loop boot on your computer. Remove the
memory card and replace it with the good one.

Causes of Blue Screen problems

  May 20, 2011    

Blue Screen is also known as Blue Screen of Death (BSoD). It is called Blue
Screen because it display only blue color in computer monitor with its error
message when the operating system of the computer experiencing a problem
with its software or hard. BSoD also display the possible reason why its
happening to your computer. BSoD appears when there is incompatible
software and hardware that was installed in the computer.















<


Here are some possible causes of BSoD.

Defective Power Supply Due to over heat.

         Someone called me up from HR Department and told me that
her computer monitor display only blue color with error message. As,
I went to check her computer, all I can see in her monitor was BSoD 
error.

I open the system unit and look for any possible reason why this error
appeared. I touched the power supply  inside the system unit and 
it feels so hot. I removed the power supply from system unit and open it 
up. The two fans of power supply was already stock up. That's the time
I decided to replace it with the new one and install it. When I turn on the
computer, the BSoD is now gone. I concluded that power supply cannot
supply the electricity needed by the computer to function normally that is 
BSoD comes up. 

Incompatible Memory Module
            I installed additional  memory to one of our computer in our
production office to upgrade it. I turned on the computer and BSoD displayed
on monitor. I suspected that the cause of BSoD was the memory I have installed.
I remove the memory and turn on the computer. The BSoD  is gone. It means
that the memory I installed was not compatible to the motherboard.


Hope my experience regarding BSoD will help you to identify the problem
that trigger the BSoD error.

How to fix corrupted pst files?

  May 15, 2011    

             Microsoft Outlook 2003 was the primary client email application used in
our office to send and receive email messages. In my work experiences, I always
encounter a problem with Microsoft Outlook 2003. There are times that when you
open the Microsoft Outlook 2003, messages from the Inbox folder are not
displayed. Sometimes, some messages cannot be open and cannot be read.
             The reason why it happen was the pst file of Outlook 2003 is corrupted
and damaged. All messages and settings of Outlook 2003 were stored in the form
of pst files. Microsoft Office have a solution to this problem. There is a repair tool
to fix the pst file.This repair tool is called SCANPST. The location of SCANPST
file is located in the following path:

For Microsoft Office 2007
C:\Program Files\Microsoft Office\Office12\scanpst.exe

For Microsoft Office 2003
C:\Program Files\Common Files\System\MSMAPI\1033
                If you cannot see the SCANPST in above path, you can use the Search
features of Windows XP, Windows Vista and Windows 7 to see the location of
SCANPST. After you locate this repair tool, double click it. When it opens up,
locate the pst file that you are going to repair by clicking the browse button. After
that, you can now click the start button to start the repairing process.

  May 10, 2011    

Suppose you have an excel files that contain thousand of data of numbers with
spaces between them.If you will remove those spaces it takes lots of time to
finish it.

In Excel, the Substitute function will ease your work to remove those spaces
because one of its function is to  replaces a set of characters with another.

The syntax for the Substitute function is:
Substitute( text, old_text, new_text, nth_appearance )
Here is the syntax of Substitute function that will remove spaces between those numbers.

         =Substitute(A1," ","")

You can see in the picture above that Substitute function removes
all spaces of cell A2.In my work experience, Substitute function is very useful.

Have you experience to plug in your Flash drive or any usb device in your computer and it doesn't show up in my computer?

Recently I experience this problem.I plug in my Flash drive, then it was detected by my pc. Unfortunately, I can't see any removable storage in my computer. I plug in my Flash drive in other pc but it was detected and showed up in my computer. It means that there is a problem in my pc. I search the internet to fix this problem and find a solution for that problem. Here are the steps.

     If you are using Vista/Windows 7, click the Windows Logo at the bottom left.


2. Type regedit, then press Enter. 

3. Registry Editor will pop up.Navigate to the following registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

4.Under HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices there will
   be registry keys with the name  that resembles the format of \DosDevice\E:
    where E can be any alphabet letter which corresponding  to your physical system
    drive letter. Normally storage devices use E or F depending on how many partition
    you have in your hard disk.
  

5. Delete the DosDevice\E: registry keys that represent any USB or FireWire
    storages devices connected on the system before.

6. Now insert and plug in the USB or FireWire device into the port again. The
