WHAT IS 45NM AND 65NM PROCESSOR TECHNOLOGY

ANSWER:-
Actually 45nm which is the short form of 45-nanometer and 65nm is the short form of 65-nanometer.
you have heard about millimeter.
1 milometer = 1000000 (10 lac) nanometer.
Then:- 45 nanometers = 4.5 × 10^-5 millimeters.
            65 nanometers = 6.5 × 10^-5 millimeters.
This means its too Small we can't see it with naked eyes.

But the question is what does it means?
The answer is ITS A SIZE OF TRANSISTORS IN A PROCESSORS.
An Intel processors contains over 8 million transistors.
Greater the size of transistors faster it works ad obviously it requires less electricity.
45nm is better then 65nm.
so for all the gamers or who have decided to buy any CPU or confuse in this technology then better go for 45nm or smaller value CPU like 32nm.

HOW TO CLEAN A CPU

SOLUTION:-

Cleaning a CPU is easy but re-fixing it may cause problem in future.

NOTE:- Before doing this,power off your computer and also remove the plug from the circuit board.
Its better to use ESD (Electrostatic discharge) during this process.

• Power off and Unplug the computer.
• Open the cabinet using screwdriver.
• Carefully unpin the processor's heat sink and unplug the wire of fan and clean it without water (Remember not to remove the processor chip.just remove and clean the heat sink).
• Again fit the heat sink but be careful as fitting the heat sink may scratch your motherboards IC chip.
• Make sure that not much pressure should be applied to fit the heat sink as it may scratch or break the plastic on  the heat sink.

REMOVING THE HEAT SINK:-

CLEANING USING BRUSH:- 

Don't use any liquid for cleaning.for better cleaning use air spray available in market.

OVERCLOCKING A CPU USING PHOENIX BIOS

HI,
Today i'll let you know how to overclock your CPU using Phoenix BIOS.
Its pretty much simple to do.

For this just start your computer and by hitting DEL from keyboard enter the BIOS.

Then go to FREQUENCY/VOLTAGE CONTROL OR MISCELLANEOUS CONTROL  OR MB INTELLIGENT TWEAKER (M.I.T).

Hit ENTER.

(There you'll see CPU RATIO or ADJUST CPU RATIO and ADJUST CPU FSB FREQUENCY or CPU FREQUENCY)

You need to first check the CPU RATION.

For adjusting CPU ratio simply hit on ADJUST CPU RATIO or CPU RATIO and then change the number to the last limit given there.

(Remember that CPU RATIO is also know as CPU MULTIPLIER or MULTIPLIER.note the CPU RATIO value)

Then go to ADJUST CPU FSB FREQUENCY or CPU FREQUENCY.
and note the current CPU FREQUENCY.

After that see this screen shots and understand:-

• ENTER MISCELLANEOUS CONTROL:-

• CPU CLOCK RATIO:-

• CPU CLOCK RATIO VALUE:-

• HOST/ PCI CLOCK FREQUENCY OR CPU FREQUENCY OR ADJUST CPU FREQUENCY:-

NOTE:-Here the max value is 700 it doesn't mean that you enter the value as 700.please be careful.just increase the value by 10 only.like i have done.
like i have entered the value as 220 then the new CPU speed will be 2.64GHz .how?
here the calculation
multiply the CPU RATIO with the CPU FREQUENCY e.g:- 220*12=2640.
which means the new speed will be 2.64GHz.
then press F10 and hit "Y" and hit ENTER.
that's it
also note that wrong way of overclocking or overclocking with fun will burn your motherboard,ram,graphic card,CPU which leads you to buy a new PC.
for overclocking collect as many information as you can then do it.

BE CAREFUL.

thank you :)

WHAT IS 32BIT AND 64BIT

ANSWER:-
32-bit and 64-bit refer to the type of CPU<OS<driver,software etc that utilizes particular architecture.32-bit is generally denoted by x86 or simply 32bit.
64-bit is denoted by x64 or 64bit.
32-bit system utilize data in 32 pieces while 64-bit system utilize data in 64 pieces.
More the data that can be processed at once,the faster the system can operate.
There are several advantages of 64-bit system as it processed the data faster than 32-bit system.

NOTE:- t is not possible to install any 64-bit program or hardware to 32-bit syste and vice versa.

thank you :)

DETERMINE IF YOU HAVE 64BIT OR 32BIT CPU

SOLUTION:-
If you're wanting to determine the version of Windows your computer is running follow the below steps for your version of Windows. Keep in mind that a 64-bit processor can be using either 32-bit or 64-bit version of Windows and that a 32-bit processor can only use a 32-bit version of Windows.

ABOUT BIOS

HI,
lets know about BIOS.
its a short form of Basic Input/Output System.
System BIOS is a chip located on all motherboards that contain instructions and setup for how your system should boot and how it operates.
 The BIOS includes instructions on how to load basic computer hardware and includes a test referred to as a POST (Power On Self Test) that helps verify the computer meets requirements to boot up properly. If the computer does not pass the POST, you will receive a combination of beeps indicating what is malfunctioning within the computer.

In most of the PCs.the BIOS has 4 main functions i.e
1) POST:- test the computer hardware and make no errors exist before loading the operating system.

2) Bootstrap loader:- locates the operating system.if capable operating system is located,the BIOS will pass control to it.

3) BIOS driver:- low level driver that give the computer basic operational control over your computer's hardware.

4) BIOS and CMOS setup:- configuration program that allows you to configure hardware settings including system setting such as passwords etc.

There are some types of BIOS fine on BIOS type pages.

thank you :)

COMPUTER BOOT UP SLOWLY

CAUSES:-
It is caused by various issues like low disk,low ram space,viruses,corrupted files etc.

solution:-

1) Scan your computer from a legal antivirus also from antimalware.

2) disable startup programs.navigate to START MENU->RUN-> type MSCONFIG->go to STARTUP tab and select the program you want to disable.

3) run a defragmemter for all hard drive partitions.

4) increase the hard drive space by deleting unusual files.
normally computer requires at least 250MBs of free space to boot.
more the hard drive space faster the speed.

5) Add memory (RAM) add some more memory to computer.

6) update the drives,windows of your computer.

7) clean the registry using some software like c-cleaner,reg-cure etc.

8) if all this doesn't work then format and reinstall the OS.


thank you :)

MISSING MICROSOFT WINDOWS .dll FILES

CAUSES:-
    A missing or corrupt .dll file can be cause by any of the below reasons.
1) Old or other program uninstalled that removes a .dll file that was required by another program or OS.

2) A program was freshly installed but is corrupted and overwrote the better and good file.

3) Corrupted program or virus containing program was installed.

4) Another user deleted mistakenly .dll file.

5) a hardware issue exists with the computer,such as bad hard drive etc


SOLUTION:-
many times its possible to download and instal .dll from net.
To download such .dll file CLICK HERE.

Also sometimes .dll files need to COPY from a particular path
eg:- (if your .dll file is missing from the path "c:/windows/system32" then just download a missing file and past it in the same path again.)

and sometimes it need to instal.

for gamer a minor problem occurs when they start a game.then the simply use to is to instal a graphic driver or Directx (directx should be the latest one).

or if all this doesn't work just try to reinstall the program.

NOTE:- update the computer for better response,also the drivers.
go to nvidia.com or your graphic cards company and download the latest update for your drives.

thank you :)

HOW TO INCREASE HARD DRIVE SPACE

HI,
Lets talk about how to increase hard drive space in windows XP,vista,7

For increasing hard drive space firstly remember that your hard drive won't contain any virus.
There are millions of virus that may lead to such hard drive problem.
Best example about increase in memory space is a MOBIL memory card.
Sometimes when virus attacks memory card it causes lowering the space.

Recently my friends memory card was filled with viruses only not even songs,wallpapers etc,but still his Mobile's memory card space was 16GBs (actually) but due to virus attack it shows only 64kbs.


Like memory card also hard drive get affected after-all its a type of data storage device.

Secondly if your hard drive doesn't contain any virus then there is many unusual file,media etc are stored which you don't like or non of your business,then delete that all.

thirdly use DISK CLEANUP.situated near the start menu.
use DISK DERANGEMENTER which is also situated near start menu.

GO to run command-type "%temp%"
hit enter
and delete all the files there.

Again GO to run command-type "msconfig"
hit enter
and navigate to -START-UP and uncheck the programs you don't want to run at startup.

COMPUTER REBOOTS WITHOUT WARNING.

causes :-
1) software issue or errors
2) hardware issue or errors.
3) heat related issue.
4) computer viruses
5) issue with operating system.

solution:-

1) software issue or errors: many time we instal new software.sometimes the software doesn't work properly,or won't start.

the error report of that software is saved bye your computer and then every time you try to run that software it gives you the same error and overwrites the old error.and these overwriting of errors requires more space,so the ram sometimes get full due to errors and PC starts hanging.these hanging result in corrupting windows file and your windows crashes.

To avoid this thing make sure to use a latest version of software suitable for your operating system.

2) Hardware issue or errors: these problem mainly occur due to newly instal drives or due to damage drives.

for this make sure are not encountered any hardware problems.
use diagnostic tools.

3) computer viruses: computer viruses are the frequent problems.computer viruses such as BLASTER VIRUS are written to reboot your computer without warning.
usually  these viruses make computer reboot after 5,10,20,15,30 minutes.

To avoid this scan your computer with antiviruses and antimalwares.

4) heat related issue: today's computers are designed to turn off automatically.
if you have heard any abnormal noises coming out from your computer recently such as high squealing this could indicate a fan may be failing in your computer.

first verify  the fan on the power supply is working by examining the back if the computer and seeing if the fan is moving smoothly.similarly verify all fans in computer.

5) issue with operating system: due to  corrupted files in operating system this also happens.
If this happens make sure to format and reinstall the OS.



NOTE:- for memory diagnostic use MEMTEST86.
              for hard drive diagnostic go to the hard drive companies official page and search there for tools.
