Everybody knows how costly is to buy a new RAM. SO, in order to get almost equal performance, we can also use some memory from our Hard Disc as virtual memory, which acts as a substitute to RAM. Follow the simple steps stated below to do so....
1. Right Click on My Computer & go to Properties
2. Click on Advanced Tab & go to Settings in the Performance Section.
3. Select the next "Advanced" Tab on the "Performance Options" window. On the advanced tab, click the "Change" button in the "Virtual memory" section.
4. Comprehend the implications of the virtual memory settings. On the "Virtual Memory" window, the "initial size" is the minimum amount of hard drive space Windows will allocate to virtual memory. The "maximum size" is the largest size to which Windows will allow your virtual memory to grow. If you set this setting too low and Windows requires more virtual memory than the maximum, Windows will likely crash or freeze and you will need to reboot. Thus, you should select (or keep the selection as) "System managed size." By allowing Windows to manage the virtual memory, Windows will increase and decrease the size of the virtual memory as-needed. It is not recommended under any circumstances to select "No paging file" because this can cause system instability.
5. Choose your virtual memory settings. On the "Virtual Memory" screen, you may modify your virtual memory settings in accordance with Step 4. Once you have made your settings, click the "Set" button. Windows will ask you to reboot. Once you do, your virtual memory settings will be changed.
