> What is Safe Mode ?
Safe mode is an alternate boot method for Windows operating systems that makes it easier to diagnose problems. The only startup programs loaded are the operating systemand drivers for the mouse, keyboard, and display modes display. It is often possible to get a system to start in safe mode when it won't start normally. To start in safe mode, press the F8 key while the system is booting and select "safe mode" (or the safe mode option you want) from the menu that appears.
>What is Last Known Good Configuration ?
The Last Known Good configuration" is one of the methods which are used to repair our computer system. In this method a restore of data from the backup is not required. This "last known good configuration" is a backup replica of the existing configuration which is stored on the registry key "HKLM\System\CurrentControlSet". This registry key is always updated whenever the system is shut down by the user after successfully and effectively logging on. Our system can be repaired by restoring information from this updated registry key. For instance in case when we install some driver which causes our operating system not to be loaded, this type of repair is helpful and useful.
So it is a very good practice to repair our system without any loss. So whenever we see our operating systemfails to load, simply press F8 and when the message "please select the operating system to start" appears, just select the Last Known Good Configuration. This option can be seen under the "Windows Advanced Options Menu". The Last Known Good Configuration is only useful in the case if we have not logged on yet. Whenever we logon and then shut down or even restart, all of the current configurations always become the "Last Known Good Configuration".

>What is the Blue Screen of Death and what could be it's causes ?
Sometimes bad or flaky memory (RAM memory, not your hard drive) can cause seemingly random system crashes. If you have just the right combination of programs open and system memory in use, and your computer tries to access a "bad spot" on a RAM chip, the results can be unpredictable. Or they can be the Blue Screen of Death. You can try replacing your RAM sticks one at a time to see if the problem goes away. This involves opening up the system unit and looking at scary wires and stuff, so for some people just living with the problem may be a workable option.

More likely, you have a software problem. Some programs just don't get along... they trample on each other's memory spaces and confusion (or the BSOD) results. And it seems that Windows just gets old and cranky the longer you have it installed. You may solve the problem by using the System File Checker, or if all else fails, by
re-installing the Windows operating system and/or your software packages. If the problem seems to be limited to one particular program, try re-installing just that one first.

Spyware or a computer virus can also make strange things happen.
> What is Cold Boot and Warm Boot ?
A cold boot means turning it on from a powered-down state. A warm boot is pressing the restart button when the computer is already on.

> What is Disk Cleanup?
Disk Cleanup is a feature of Windows that enables a user to delete system / junk files safely.
For example, by using the disk cleanup feature, you can free up a considerable amount of space on your pc, like getting rid of TIF (Temporary Internet Files) and other 'useless', and not required, files.

> What is Disk Defragmentation?
Disk defragmentation describes the process of consolidating fragmented files on your computer's hard disk.
Disk defragmentation describes the process of consolidating fragmented files on your computer's hard disk.
Fragmentation happens to a hard disk over time as you save, change, or delete files. The changes that you save to a file are often stored at a location on the hard disk that's different from the original file. Additional changes are saved to even more locations. Over time, both the file and the hard disk itself become fragmented, and your computer slows down as it has to look in many different places to open a file.
Disk Defragmenter is a tool that rearranges the data on your hard disk and reunites fragmented files so your computer can run more efficiently. In this version of Windows, Disk Defragmenter runs on a schedule so you don't have to remember to run it, although you can still run it manually or change the schedule it uses.
> What would you do if a PC is not turning on ?First Check the Power cables and power supply.
> What is the latest Operating System ?
Windows 7.

> What is a Heat Sink ?
A component designed to lower the temperature of an electronic device by dissipating heat into the surrounding air. All modern CPUs require a heat sink. Some also require a fan. A heat sink without a fan is called a passive heat sink; a heat sink with a fan is called an active heat sink. Heat sinks are generally made of an aluminum alloy and often have fins.

> What is the difference between SATA and PATA Hard-Disk Drives?
Serial ATA and Parallel ATA are both specialized interface and data transfer devices, that are used in computers to connect peripheral storage devices. Both serve the same purpose of data transfer but differ in their basic technology, speed of performance and therefore their niche applications these days.

> What are Device Drivers?
Device drivers are small files that act like “liaisons” between hardware in a computer system and the operating system (OS). Hardware requires device drivers so that the OS can “see” the devices and handle them effectively and efficiently.

> Explain the Windows XP Boot Process ?
1.First is the POST, this stands for Power On Self Test, for the computer. This process tests memory as well as a number of other subsystems. You can usually monitor this as it runs each test. After that is complete the system will run POST for any device that has a BIOS (Basic Input-Output System). An AGP has its own BIOS, as do some network cards and various other devices.

After that is complete the system will run POST for any device that has a BIOS (Basic Input-Output System). An AGP has its own BIOS, as do some network cards and various other devices.
2.Once the POST is complete and the BIOS is sure that everything is working properly, the BIOS will then attempt to read the MBR (Master Boot Record). This is the first sector of the first hard drive (called the Master or HD0). When the MBR takes over it means that Windows is now in control.
3.The MBR looks at the BOOT SECTOR (the first sector of the active partition). That is where NTLDR is located, NTLDR is the BOOT LOADER for Windows XP. NTLDR will allow memory addressing, initiate the file system, read the boot.ini and load the boot menu. NTLDR has to be in the root of the active partition as do NTDETECT.COM, BOOT.INI, BOOTSECT.DOS (for multi-OS booting) and NTBOOTDD.SYS (if you have SCSI adapters)
4.Once XP is selected from the Boot Menu, NTLDR will run NTDETECT.COM, BOOT.INI and BOOTSECT.DOS to get the proper OS selected and loaded. The system starts in 16-bit real mode and then moves into 32-bit protected mode.
5.NTLDR will then load NTOSKRNL.EXE and HAL.DLL. Effectively, these two files are windows XP. They must be located in %SystemRoot%System32.
6.NTLDR reads the registry, chooses a hardware profile and authorizes device drivers, in that exact order.
7.At this point NTOSKRNL.EXE takes over. It starts WINLOGON.EXE that in turn starts LSASS.EXE, this is the program that display the Logon screen so that you can logon.

Troubleshooting GK Having patience is extremely necessary once troubleshooting pc issues. turning into annoyed or not taking notes will extend the troubleshooting method considerably. continuously take careful note of things that will have modified. Did you put in a replacement piece of hardware or thusftware? Was there a foul electric storm or an influence outage? All of those things is also a part of the underlying drawback so take careful notes. Before you click "OK" or restart your pc, make certain to put in writing down any error messages. Take careful note of what programs you were running at the time. If the message is during a windows box, typically clicking Details will offer further info.
