ProBook 4720 s Windows 7: I have 4 GB of RAM but only 2.99 GB is usable

• I have 4 GB of RAM, but only 3.75 GB are usable/available: why?

  I bought a desktop computer Dell Inspiron 400 in 2010.

  It has a processor AMD Athlon 2650c installed with a captivity of memory RAM of 4 GB but only 3.75 GB is usable or available, why? Where's the other Go.25?

  There are a few possibilities.  If you use a 32-bit operating system, there is not enough bits of address (to use) more than this amount of memory, so the rest (le.25) is literally inaccessible to the system.

  If you have a 64 bit OS and it still shows, it is because your system is reserving some of them to be used for low level such as video memory system functions.

  Where are you seeing the 3.29 "usable"?  It would be fair that the rest is in fast cache.

  I deleted an earlier version of Acrobat Pro from my computer. Still, I get the same message.

  Hi John,.

  Please specify if you have purchased DC Acrobat or Acrobat 11 or upgrade you to the latest patch for Acrobat 11, that is to say 11.0.11 so that we can help you accordingly.

  I wonder if you have checked your system requirements before you download Acrobat.

  I would also ask to share with you the screenshot of the error message with us.

  You could probably uninstall Acrobat using cleaning tool. Here is the link for the same thing.

  My PC running the 32-bit version or 64-bit Windows?

  http://Windows.Microsoft.com/en-us/Windows7/find-out-32-or-64-bit

  http://Windows.Microsoft.com/en-us/Windows7/installing-and-reinstalling-Windows-7

  Windows 7 64 bit comes in handy when you need to deal with at least 4 GB of RAM or more. Windows 7 32 bit can use up to 3.2 GB of RAM. Because the address space of memory is much larger for 64-bit Windows, this means that you need two times more memory than the 32-bit Windows to accomplish some of the same task, but you are able to do much more, you can have more apps open, do things like run a virus scan in the background it will affect the performance of your system. 64-bit Windows 7 is safer too, malicious code cannot easily infiltrate it, drivers are more reliable because they must be signed before it can work with 64 bit Windows 7.

  Regarding compatibility, you need device drivers 64-bit hardware devices, you may have. In addition, there is no 16-bit subsystem in Windows 7 64-bit, which means, your applications must be 32-bit only, not 16-bit Installer or programs uninstaller. Also, if you decide to switch to Windows 7 64 bit in the future, there is no way to upgrade from 32-bit Windows, clean install only.

• I have 4 GB of RAM, but when my i play any game, my CPU fan runs at high speed and my system gets shut down within minutes.

  I have 4 GB of RAM, but when my i play any game for example NFS most wanted, my CPU fan runs at high speed and my system gets shut down within minutes. Help me solve this problem

  If you overclocked?  If so, cancel that.  If the games you play are poorly written, it is not that you can do about it.  If you have not cleaned the dust and lint from your computer within a certain time, you should do that because it accumulates and causes overheating.  For desktop computers, remove the cover and carefully use compressed gas to blow off the dust, especially around the fins in the processor heat sink and air ducts.  For a laptop, I'll ring gas compressed through the ventilation openings.

  Good luck.

• Windows XP: I have 448 MB of RAM available. What happened to the 64 MB of RAM lack and how can I solve this problem. Thank you

  I am trying to install application constant guard Internet Security of Comcast.  After trying to download and install the product, I get and RAM error message indicating I need 512 MB of RAM to install this product, and I only have 448 MB of RAM available.  What happened to the 64 MB of RAM lack and how can I solve this problem.  Thank you

  The only way to see more of RAM is to install a graphics card and disable the onboard graphics of your motherboard. If you do this, you should be able to see all the 512 MB of it.

  That being said, I will repeat what I said before...
  You can always buy more RAM and install it on your motherboard. Go to crucial.com for more information.

  In addition, you should review install 'Internet Security' application or suite. They are not necessary (you can easily configure Windows so that it is very safe) and they often ruin the performance of a PC.

• I have installed 2 GB RAM but memory in drive c is 78 GB how to develop

  information: I install windows vista (Home premium) in acer veriton s661 in the information system, the RAM is 1.00 GB (c drive Go 76.3) pass to 2,00 GB but c drive not extend the same memory in GB 76.3 How unzip?

  To add to the response of Rey, if you want to significantly increase your hard drive space (76.3 GB you have now) you need to add a new larger hard drive - you can get this done professional if you are not competent to do it yourself. You may be able to regain some disk space on your hard disk existing with the disk cleanup tool:

• have 8 GB of ram, but seems like all cached then run IE9 makes so slowly. Is there a way to clear the cache

  have hp computer with 8 GB of RAM running on vista 64-bit and see lately all put physical memory cached in the Manager of tasks with almost no free left.

  is there a way to clear the cache?

  Thanks in advance

  The value specified in the 'Cache' in the Task Manager includes more than the real system file cache. In particular, it includes the pending list. There are programs and files that have been previously referenced and the Windows file previously read. The waiting list pages can be reused immediately if an application requires more memory. There is an article with the definitions of the terms used and an introduction to the management of memory here:

  http://blogs.msdn.com/b/ntdebugging/archive/2007/10/10/the-memory-shell-game.aspx

  To see your use of memory more in detail, download and run Process Explorer from here:

  http://TechNet.Microsoft.com/en-us/Sysinternals/bb896653

  Go to view > system information. (or Ctrl + i). Select the memory tab and view the information in the left column under Commit Charge and physical memory.

  To better answer your question, please provide the following details.

  • Describe in more detail what you mean by Internet Explorer is slow.
  • Being of other applications of runs slowly or only Internet Explorer?
  • How many tabs you have open and how many other applications is running when Internet Explorer is running slowly?
  • You are running Internet Explorer 32-bit or 64-bit? See this article to know that if you do not know: http://blogs.msdn.com/b/ieinternals/archive/2009/05/29/q-a-64-bit-internet-explorer.aspx
