ENABLE DIRECT MEMORY ACCESS

It's not only disabling things that can increase PC speed. Enabling features that are disabled by default can significantly speed things up.

Direct Memory Access (DMA) is a feature that allows your hard drive and CD-ROM drive to transfer data directly to and from the memory without using the microprocessor. Basically, Direct Memory Access decreases the CPU load and thus makes your system work faster.

Direct memory access is usually enabled by default for devices that support it. However, sometimes you might need to manually enable DMA, especially if the device was improperly installed or a system error occurred. To enable DMA, do the following:

1. Click on the Start button, type devmgmt.msc in the Search box and hit Enter. This will open Device Manager. Click on Confirm if UAC prompts you so.

2. In the left-hand pane, expand the IDE ATA/ATAPI controllers by clicking on the + sign

3. Locate the icons that have the word Channel as part of their label

4. Right-click on the icon, and then click Properties

5. Go to the Advanced Settings tab, and then check the Enable DMA checkbox under Device Properties.

 6. Click OK and you are done.
