Since two weeks I am unable to connect my dedicated computer to the Internet.  When I go into the network settings, it says everything is working and then I'm connected.  But when I try to launch Google chrome, it says it crashed and cannot connect. I cannot even get an update for Avast Antivirus.  

Please help me.

My computer is running properly with Windows Vista RAM 2 GB. Sometimes, when I try to open some application an error message appears on the screen, "physical memory is too low, unable to execute the operation".  But after restart all is okay.

Why  am I fetching this kind of message?

I am running Windows 7 Professional and would want to create a system image to backup all the files in my computer. I don’t have any third party utilities to do this. Is it possible to create one in Windows 7? If so, How can I do this? Can I save this to any disk so I can use it in the future to recover from any crash?  Please send me step by step instructions. Thank you in advance.

I want to know how to automatically lock my Windows 7 computer, when I’m out or when I’m away for a short period of time. We have kids in our house and they always play with the computer.  I have work to do and I do not want them to turn the PC on and off.

This will be a waste of time. So I want to know if there is a way that I can lock it, while I’m not on my desk. Help!

I have Windows 7 installed on my computer. I am receiving series of notifications popping up on my screen every time I started browsing. The alert are the things that I knew already like my Windows Firewall is off and I need to turn it on, I don’t have antivirus so I should find one online. I want to know if there is a way to disable it temporarily.  Because it is annoying at numerous times.

I have Windows Vista installed on my computer.  Due to a virus attack, I have to install a fresh clean copy of Vista. After the installation, I saw a folder named Windows.old on my drive C:

I don’t have much space on my hard drive, so I need to delete any unused files or folder on my computer. Is it safe to delete Windows.old?

Because when I try to delete it, there is a alert box that appears telling me that I need administrator rights. Is it safe to delete it?

And if yes, how can I delete it?

Thanks in advance.

I had an update from my Windows 7 computer labelled as KB971033. After this update, it slows down my computer system. And I started to get a notification that my Windows is not genuine.

This operating system was pre-installed when I bought my computer. So I really don’t know if this is genuine or not. But beforehand, I saw on my System that my Windows is already activated. How can I remove this update from windows? Help please.

When I try to edit my registry to correct some errors, I could not open the Registry Editor window.

I am having error that the Registry editing has been disabled by Administrator.

I did not disable it and never use it for quite some time now.

I am running a Windows XP SP3. Everything is up to date. I already run my antivirus, but no threat found.

How can I enable my Registry Editor again?

Thanks in advance.

I have a legal copy of Windows XP. But I receive a balloon from my task manager that says the copy of my Windows is not genuine. So when I try to validate it, the validation could not be complete. Why does it fail validation? I have the product key with me and when I bought my computer, the original Windows XP disk is also installed on my computer.

Now my whole desktop is black in color.

How can I validate it? Help please.
