your computer is running low on memory. quit other programs and then

Can you run the player and post a snip of your resource monitor memory tab for me?

Windows Media Player may erroneously deliver the message “Your computer is running low on memory. Quit other programs, and then try again” when attempting to play DVDs, stored movies or other media. This message can be the result of an unregistered Windows Media Player .dll instead of an actual scarcity of memory.

To fix this issue, follow these steps:

1. Launch a commpand prompt in administrator mode. Navigate to Programs > Accessories > then right-click “Command Prompt” and select “Run as Administrator”
2. Copy and paste the following command: for %a in (%systemroot%\system32\wm*.dll) do regsvr32 /s %a into the command prompt.
3. Press enter and wait for the command to process.

After performing these steps, re-attempt usage of Windows Media Player.

Open resource monitor from the task manager, or type it into the start menu. Then use the snipping tool to capture an image of the memory tab.

also check the paging file settings

Change the size of virtual memory

If you receive warnings that your virtual memory is low, you'll need to increase the minimum size of your paging file. Windows sets the initial minimum size of the paging file at the amount of random access memory (RAM) installed on your computer plus 300 megabytes (MB), and the maximum size at 3 times the amount of RAM installed on your computer. If you see warnings at these recommended levels, then increase the minimum and maximum sizes.

1. Open System by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking System.
   
2. In the left pane, click Advanced system settings. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
   
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.

Increases in size usually don't require a restart, but if you decrease the size, you'll need to restart your computer for the changes to take effect. We recommend that you don't disable or delete the paging file.
