Tip & How-To about Computers & Internet
Most of the times we observe that our system seems to gradually slow down. Here below i am listing five basic and easy steps
that can help you speed up your Windows XP computer.
1. Clear the Prefetch Folder :The Prefetch Folder contains files that keep getting stored on your computer whenever you launch any program or application. Deleting these files clears up space on your system that might have caused the slow down. Here is how you need to go about it.
Click Start..click Run..type Prefetch and click ok. The prefetch folder will open up. Press Ctrl and A together. This highlights the entire contents of the folder. Press the Delete key on the keyboard and confirm the deletion. Once done close the prefetch folder window. Now right click on the recycle bin icon on the desktop and right click and select empty recycle
bin and then confirm the deletion.
2. Disable Startup Items: Certain programs get initiated in the background as soon as your system starts causing the system to slow down. These programs are actually not required on startup but because they get initiated it affects the system performance. Here below i am listing the steps to take care of this issue.

The System Configuration utility window will open.
Click on the Startup tab on the top right. Click on the disable all button. Once done, in the list above, you will see many options with checkboxes. Please check any option that indicates your antivirus program software and internet service provider.
Click Apply and Ok. Please restart the system once.Once the system reboots you will get a message coming up saying "You have used the system configuration utility...." Please check the option below that says" Do not show this message again" and click OK.

The barometric pressure (BARO)
The manifold absolute pressure (MAP)
The intake air temperature (IAT)
The engine RPM
P0121 The predicted air flow and the predicted MAP combined are outside a calibrated range for more than 3 seconds.
Inspect thoroughly for any type of leak or restriction
Air leaks at throttle body mounting area and intake manifold sealing surfaces
Throttle body for dirt, debris, and coking--Refer to Throttle Body Cleaning.
Increase the engine speed slowly to 3,000 RPM, then back to idle.
Exit from the snapshot and review the data.
Observe the Mass Air Flow (MAF) Sensor parameter frame by frame with a scan tool. The MAF sensor g/s should change smoothly and gradually as the engine speed is increased and is returned to idle.
If the MAF sensor g/s does not change smoothly and gradually as the engine speed is increased and is returned to idle, refer to DTC P0101 or P1101.
Broken throttle shaft
Any throttle body damage
If any of these conditions exist, replace the throttle body assembly.
