Preventing low memory problems

When your computer doesn't have enough memory,Windows and your programs can stop working.Low memory problems occur when your computer runs out of RAM and becomes low on virtual memory. This can happen when you run more programs than the RAM installed on the computer is designed to support. Low memory problems can also occur when a program doesn't free up memory that it no longer needs. This problem is called memory overuse or a memory leak.

To prevent low memory problems

• Install more RAM

• Increase the paging file (virtual memory) size
  • Windows automatically attempts to increase the paging file size the first time your computer becomes low on memory, but you can also manually increase it up to a maximum size that is determined by the amount of RAM installed. 
    steps to increase the virtual memory size manually in win 7
    1. Click to open System.
    2. In the left pane, click Advanced system settings.
       
       
       
       
       
       
       
    3. On the Advanced tab, under Performance, click Settings.
    4. Click the Advanced tab, and then, under Virtual memory, click Change.
    5. Clear the Automatically manage paging file size for all drives check box.
       
       
       
    6. Under Drive [Volume Label], click the drive that contains the paging file you want to change.
    7. Click Custom size, type a new size in megabytes in the Initial size (MB) or Maximum size (MB) box, click Set, and then click OK.

How to Change Windows 7 Logon Screen Background...


1. The image you need to set as the background should be a .jpg file and it’s size should not exceed 245KB.The image resolution can be anything of your choice. However I prefer 1440 x 900 or1024 x 768.

2.You will need to copy this image to C:\Windows\system32\oobe\info\backgrounds
You will need to create that path if it does not already exist on your computer.
3.Now open the Registry Editor (Start -> Run -> Type regedit) and
navigate to the following key
HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background
If Background does not exist rightclick LogonUI, select New and then Key, and then name it Background.
Now locate OEMBackground (listed on the right side). If it does not exist, right-click Background and
select New and then DWORD and name it OEMBackground.

4. Double-click on OEMBackground and set the Value Data to 1.

5.Now log-off to see the new logon screen background. If you would like to revert back to the default
background, just set the Value Data back to 0.
