In the old days, memory components had an extra chip called a 'parity chip,' and part of the BIOS test was a parity test. You might also see an error that references memory problems. (You can also look it up by checking the BIOS manufacturer's Web site.) However, you're far more likely to see text rather than numbers, as in Hard drive controller failure or the always amusing Keyboard error, press F1 to continue. Today, if you see an error number, you need the documentation that came with your computer to interpret it. Some BIOS errors appear as numbers, and at one time all BIOS manufacturers used the same numbers (the numbers that IBM used), but that changed. The system reports hardware and BIOS errors to the screen, along with beeps to get your attention. If the user sees an error message during the POST, or if the computer simply hangs before the OS starts, the problem is in the hardware or the BIOS. Power supplies aren't expensive, but replacing them is a boring, labor-intensive exercise. If it's not the plug, it's probably the power supply-the most vulnerable hardware component in your system. Ask the user to pull the plug and reinsert it, citing a need to 'check the polarity issues.' (Try not to giggle.) You'll be amazed how often users will report, 'Hey, that worked.' The user might say, 'Of course, it's plugged in,' but you need to know whether that's the truth. Users often don't check whether their unresponsive computer is unplugged, and when you mention this possibility, they're embarrassed if it turns out to be the cause.

Here's an old administrator's trick for dealing with unplugged computers when you're working with a user over the phone. Is the user complaining that nothing's happening when he or she presses the power button? If so, first check the plug.

(For the purpose of this discussion, I assume you're using Windows 2000 or later.) Let's walk through the startup process to see what happens at each step and to understand the meaning of any error messages you encounter. Therefore, you're more likely to encounter an OS problem when a system fails to boot. Computer hardware has become more reliable over the years, and-thanks to advanced BIOS features-the computer's ability to track, diagnose, and control that hardware is more robust. But in the days of MS-DOS computers, the POST took longer than OS startup, and hardware was the source of most boot-failure problems. The phrase 'boot failure' describes both machine and OS problems. To diagnose and cure such maddening problems, you need to understand how the boot process works. Typically, users report that something untoward happened during the startup process-either during the computer's Power On Self Test (POST) or during the Windows startup procedures. Use the arrow keys to navigate.Every network administrator has received calls from users complaining that their 'computer won't start'-a nebulous, uninformative phrase that can cause quite a bit of frustration. In the above screenshot, it is under Advanced BIOS Features. Note that there are not many options in a BIOS, so just go through every page if you have to until you see something like First Boot Device, Boot Order, Boot Management, Boot Sequence, Advanced BIOS Features or Advanced Boot Options. Now that you are in the BIOS, find the boot order section.In any case youвЂ™ll see a message such as Press FX to enter setup or something similar. This key can be the SUP key or one of the functions keys (FX). You can enter the BIOS by pressing a specific key when requested, itВґs usually requested at the beginning of the computerВґs boot, when the screen is still black. The first thing you have to do is restart your computer and enter the BIOS.

Changing the boot order on a PC is mostly done in order to boot from a recovery disk or from an OEM disk to run some kind of Windows disinfection or repair software. However, here go a few general guidelines.Д«y changing the boot order, you can force your computer to boot from a CD/DVD drive, a floppy drive, a USB drive or even off the network. Whenever you have queries on general IT knowledge, we advise you to refer to the instructions supplied by either your computer or your Operating System provider.
