Your PC isn’t doing anything, the screen is a mess, the hard-drive is trying working away. Is there anything you can do, rather than just reach for the reset button?
Here are some tips for dealing with those times when Windows hangs:
Don’t keep clicking things
Windows buffers (meaning that it remembers) all these clicks and will implement them when it catches up, preventing you from continuing with what you want to do, and possibly causing havoc. Show a little bit of patience.

Check to see if your PC has crashed
Before you hit that reset button it is wise to check if your PC has actually crashed. To do this simply press the Caps Lock key, and check whether the ‘Caps Lock’ light goes on or off; if it does then your session may be recoverable. You may have to wait to see a response.

Try to close any non-essential applications
You can try to close any programs that don’t have any of your precious work open in. Try right-clicking on their button on the taskbar (the bar with the time and the Start menu on it) and clicking ‘Close’. A little patience may be required here if the machine is running slowly.

If your mouse is really slowed down you may have more joy with the keyboard. Hold down the alt key and press tab to change between programs. When the non-essential application appears try to close it by holding down the alt key and pressing F4. All recent versions of Windows have a built in application called Task Manager. To run it simply hold down Ctrl and Alt, and press Delete (note: Windows 2000 users will then have to press the ‘Task Manager’ button on the dialog box that opens.)

As with all these tips, you will have to wait a while to see if it appears. When it does, check the ‘Applications’ tab to see if any of the programs you are running have a status of ‘Not Responding.’ If they are, click on one to highlight it then and click the ‘End Task’ button. Do this with any other programs that are not responding then see if your computer starts to respond.

If Windows starts working again it is best to save all your work and restart the PC. A clean restart is always preferable to a hard reset.

Bellow is a list of great software which can be used to remove virus from your computer:

ComboFix – Great virus removal tool for bad effected computers.
Malwarebytes – This is another great tool to remove other virus from your computer and other malware that might be on your computer.
Dr. Web – This does not install on your computer so is great for picking up on root kits on the computer and also scans for virus.

Safe Mode is a computer start mode that only loads the bare minimum of drivers and startup programs. The purpose of Safe Mode is to help you diagnose startup problems in Windows. Safe Mode is also a great mode to run any virus scan on your computer.
If you are haven problems with your computer on startup then you will normally be able to boot into safe mode and use this to resolve the issue you are haven.
So how do you get the computer in Safe Mode? First, turn the computer off (use the power button the tower if you have to). When you turn the computer back on, you’ll want to keep hitting the F8 key on the keyboard until a menu comes up. In the list of options, you’ll see Safe Mode. Use the arrow keys on the keyboard to select it and then select safe mode. On some Dell Computer you will first need to press F12 then boot onto the hard drive then press F8.
Booting to Safe Mode takes a few minutes and you may see a black screen with a lot of text on it for a couple of minutes. After a couple of minutes you should see your computer desktop again. If the computer never progresses past the black screen with writing (be sure to give it a good 15 minutes) – then you’ve got bigger problems to worry about. You could try repeating the process to boot to Safe Mode and see if it works next time or you could try “last known good configuration” in the startup menu of options when you press F8. If neither of those work, then chances are you’ll have to reload your computer from scratch again (make sure before doing this you have all the data backed up.)

When trying to open documents while on remote location (slow connections) you maybe have travelled with your work and when trying to open a Microsoft office excel file while connected to the network is taken a very long time to open. This can be caused with network printers attached to the computer set as the default the best thing to try is to set the default printer to a local printer.

Please be careful when editing the registry. Always take a backup before working on it.

1) Click Start
2) Click Run
3) Type regedit
4) Navigate to the following registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
5) Below ProfileList navigate to keys like:S-1-5-21-3656904587-1668747452-4095529-500
6) On the right side menu below ProfileImagePath you will see the username
7) Once you have located the profile you wish to delete, right click the long reg key as described in step 5 and delete
