Solutions: Tweaks can help keep old computer running

I have a Dell Dimension 2350 with 512 MB of RAM. My Internet is slow and I receive low virtual memory messages. I increased my virtual memory to 500 MB but did not notice any changes. Should I get a program to clean up my over 1,000 registry issues to speed up my computer? If so, which one would you recommend?

512 MB RAM is very bare bones. I know this is an old computer, but you would benefit with an upgrade to 1 GB (the limit on that model if the online specs are correct). I do not recommend any registry cleaner and absolutely stay away from anything you see advertised on TV.

Here are some things you can do: Click Start, Run, type MSCONFIG and click OK. Click the Startup tab. These are the programs that start up automatically when you boot. Many of them are not necessary. Every PC will be different, so you will have to do some digging to find out what these programs are if you don't recognize them. Internet searches on the process name can be helpful. Each process can be prevented from automatically starting by un-checking it.

Some other things: Do a hard disk defrag and a general disk space cleanup. Right-click the C drive, choose Properties, click the Disk Cleanup button. Make sure that the PC's fan is not caked with dust. If it is, a blast from a can of compressed air will fix that.

I am using Windows 7 on a Toshiba laptop. I frequently have to send messages to different people and sometimes I get this message: "Cannot deliver this message as your Default Mail Client is not properly installed." I don't understand this message. I have no problem sending or receiving email.

What is your email client? That is important information. I would look at which program is set as the default email program for your PC, and if it is not set correctly, set it. Click Start, type default and then click the Default Programs link at the top. Click set program access and computer defaults. Select Custom and then click the down arrow to the right. Microsoft Live will show as a choice unless you've already installed your email client program information.

Sometimes when I am trying to get online, I get this message: "You are not currently logged into your computer as an administrator. Please log out and back in as an administrator and then restart the installer." After this message the only way I know to get online is to turn the computer off and unplug the modem for at least 10 seconds. This will usually make it possible for me to go online.

My recommendation would be to run the Microsoft Defender Offline and have it look for and remove any virus/malware. Go to to read about Windows Defender Offline and create your own CD/DVD. Once this is completed, boot from that CD (when your computer reboots, it will ask you to press any key to boot from the CD). This will automatically run the Windows Defender Offline without interference.
