Overclocking a Processor

All processors come with a preset frequency at which it works. These types of processors don’t work above the maximum preset frequency by default. But the new ones like the Intel Core i5 and i7 processors come with internal Overclocking option. These processors have the capacity to over clock near 700 MHz. But the old processors won’t do it by default as they are designed not to do so. There are a lot of tech support websites that offers articles on different types of overclocking; but not all of them describe the harmful effects of manual overclocking.

What is Overclocking?
Overclocking is the process in which you set the processor to work at a frequency that is higher than its preset max value. When you overclock the processor, it can cause the processor do overwork and this causes overheating, increases RAM speed, leads to voltage drop etc. So, if you are planning on overclocking your processor on a whim, you will definitely smolder that piece of silicon.
Overclocking effects on processors are totally different. Same model processors will show different charts and levels when overclocked. If one shows performance, other will literally be on fire. The thing is that most Quad Core or Core 2 Duo processors don’t show any difference when overclocked. You should have an external cooler and good ventilation cabinet. Here are some instructions for Overclocking.

1. Download the programs - CPU-z, OCCT, Prime95.
2. Open the BIOS settings from boot. In the advanced tab, change the FSB by 10 MHz, this is the minimum increment.
3. Go to Windows, check and continue this process until FSB equals 60 MHz. After that go to Windows and monitor the temperature with Real Temp. The CPU temperature should not be above 60oC.
4. Using the Diagnostic tools, check the RAM speed. Don’t let the RAM speed cross the rated speed. Also set PCIe frequency to 100. You can go to BIOS again and raise the FSB by 10 MHz. After that check the Processor and RAM status using OCCT for 1 hour.
5. Overclocking increases power consumption. So in case a BSOD occurs or black screen occurs or if the system restarts abnormally, go to BIOS and raise the VCORE voltage by minimum level.
6. When you find that FSB hits the limit, stop it there and drop it to the last point. In case you hit black screen or non boot situation, do a CMOS reset and restart.

If you check other tech support forums you can know about various other problems caused by Overclocking.

Turning OFF Password when Rebooting your Computer

Security systems are obligatory components in Operating systems. Windows platforms are no different in case of security systems. Microsoft has packed the legendary Windows platform with a lot of security features to avoid misuse of user accounts and computer systems. Some security features are for networking security whereas others are for personal security and user account security. If you search Windows Help Index in your Windows platform, you can read the different security features implemented in the platform.
Windows, in normal cases, involves you in entering a password to log in to your user account and to access your computer when it reboots. This process is a part of the security measure to protect your system from unauthorized individuals or other users. Every operating system has its distinct way to restart, in case you want to reboot the machine.  If you want to, due to any reason, you can disable the password prompt. There are some instructions given in the following part that will help you to turn off the password prompt while rebooting your computer.

In Windows 7 Platform

1. Click on the Start Button located on the Taskbar on the bottom part of the desktop.
2. Type the text “control userpasswords2” in the search box option in the Start menu.
3. Uncheck the box aligned to the option that says, "Users must enter a user name and password to use this computer" in the User Accounts window that appears.
4. Enter your account password and click on Confirm link to complete the process.

In Windows Vista Platform

1. Click on the Start button located on the bottom left corner of the Desktop. The Start Button is a round button that bears the Windows emblem.
2. Click on the Run option in the Start Menu.
3. Type "netplwiz" in the text box in Run Window and press "Enter."
4. In the User accounts window opened, uncheck the box aligned to the option "Users must enter a user name and password to use this computer" and click OK.
5. In the text fields (White Boxes) given there, enter the username and password (login details) to login automatically when you restart the computer. Now click on the box aligned to "Automatically Log On" option and press the OK button after that.
6. Now close all the applications and restart your computer. You can see that the password page is disabled.
You can check the Windows Help feature more details regarding the security features in Windows.
