Tip & How-To about Computers & Internet
It has been one of the dilemma of computer users is to identify what is really
causing the failure in their computer. Often they think that they bought a
defective product since they are getting these kind of errors in the computer.
Having an error on your machine does not mean that the machine is defective or
needs parts replacement. for all we know it might just need some simple
troubleshooting steps to fix the issue. Here is a tip where you would be able
to know if you need to bring your computer to a service shop for parts
replacement or you can try to fix it at home by doing some troubleshooting
steps that would help fix software failure in the computer system.
On a Windows based operating system, you should always know when the issue happens. It will help much to observe your computer on how it boots up and what it does before you get to the desktop screen. Take a note on where and when exactly the error occurs.
This is an issue where there are no lights on the power button of your computer, whether it is a portable system or a desktop computer. Obviously this is a hardware failure. surprisingly, discharging the flea power of your computer sometimes resolves these kinds of issues. Otherwise, you will definitely need to have a local technician look at your system for parts replacement.
Note: flea power is the charged power of our computer system. A computer system is made up of electronic components such as capacitors which hold electronic charges. To be able to discharge it, you should disconnect all power source from your computer and hold the power button for at least 5 seconds.
POST is an abbreviation for Power On Self Test. as the name implies, it is the test that a system goes through to test the basic hardware components needed for a computer to boot. The components that it tests are as follows: Processor, BIOS (Motherboard), Memory, keyboard and video card. If there is a POST failure, the system would give you a black screen with lights on the front panel. Sometimes it will give you beeping sounds which would normally mean that you have a memory failure on your system. If you encounter such issue, you will need hardware technical support to guide you isolate further on what could be causing the failure.
Boot failure is when the computer is able to complete post. You will be able to know this if you hear a single beep on your computer. Isolating a boot failure from a post failure simply requires you to boot to the System Setup/configuration Screen (BIOS). If you are able to get to the BIOS, that means all the POST hardware component are good to go. However, booting to the BIOS differs per system. You just need to do trial and error on the following keys to tap as you turn your computer on.
To isolate an issue whether it is a software or a hardware issue, you just need to boot from the BIOS. If you are able to boot from the BIOS, chances are it is not a hardware failure and needs servicing.
If booting to the BIOS works, to further isolate the issue whether it is the advanced software, you need to boot to Safe mode. Safe mode is a troubleshooting state where only the basic applications and drivers are active. If you are having errors or boot failure, try to boot to Safe Mode. If you do not encounter the failure in Safe Mode, that means that there are advanced software being loaded in your operating system that fails. It is just a matter of knowing what that software is.
Booting to Safe Mode:
1. turn computer on and tap on F8 before Windows starts.
2. You will be getting the Advanced Boot options. Use the arrow keys to get to the option for Safe Mode.
Safe Mode Definitions:
Safe Mode: Just basic software are being loaded. Network drivers are not included which means no internet connection
Safe Mode with Networking: Basic software and Network drivers are being loaded.
note: for Vista or Windows 7, it includes wireless network drivers. This means that you can still connect to the internet with a wireless connection. In Windows XP, the wireless driver is not included even if you boot to Safe Mode with Networking
Safe Mode with Command prompt: this is a troubleshooting state where you will be able to utilize DOS based commands.
