The Windows Bluescreen Is A Critical Windows System Error. Reasons And Resolutions For A Very Common Computer Problem.

no comment Posted by catering

The Windows blue screen is the term used for when the Windows operating system has received a serious and critial system error. It is a common Windows problem and can seem quite threatening if you have never seen it before. The blue screen displays the error codes and messages that has caused your computer to shut down to stop it gaining critical damage.

There are many blue screen causes as follows:

Registry corruption, viruses, hardware failures, device driver incompatibilities and resource conflicts are some of the more common problems. Some issues are easier to solve and rectify than others. But firstly, try to obtain some information from the message displayed on the bluescreen. For example, if a .sys file is mentioned within the script then this indicates that there is a driver issue. When you restart your computer go to your ‘Device Manager’ (within the ‘Control Panel’) to see whether there are any warnings for an incompatible or outdated device driver. If there is, disable the driver to see whether this solves it.

You can also view the Windows ‘Event Log’ to narrow down the problems listed on your bluescreen. Read the errors that are shown here to help eliminate the causes. The ‘Event Log’ is found via the ‘Control Panel’ – ‘Administration Tools’ – then ‘Computer Management’.

This may all sound complicated but sometimes computer problems are not easy to solve. Run a virus check on your system to see whether any malware has wormed it’s way in to your computer. Viruses can seriously cause harm to your PC so make sure that your antivirus software is of a decent standard.

A corrupted registry over time will cause your PC to have a bluescreen. Install a Windows registry cleaner to resolve your system registry problems. A registry cleaner is a fantastic piece of software that not only cleans and tidies up your registry but after doing so, will keep your PC running to it’s optimum performance and speed. The Windows registry is the nerve centre of your system so maintaining this component will seriously look after the functioning of your PC.

Make sure that you have the latest Windows update. The Windows operating system is constantly being upgraded to keep on top of technology so follow suit and update it when asked. The same is asked for when you install new hardware. Check that it has the latest device driver. Outdated drivers create havoc with your computer leading to many problems – the Windows blue screen being just one of them. Check within the ‘Device Manager’ to see if any warning signs have appeared indicating device driver problems. If there are, then disable or uninstall the driver to see whether the Windows blue screen stops appearing.

How To Use The Magic Wand In Adobe Photoshop CS4

no comment Posted by catering

Photoshop CS4 by Adobe is a difficult program to master without some expert assistance. Photoshop has three tools for making selections: The Marquee, Lasso and the Magic Wand. When I run courses on Photoshop, tools like the magic wand and the clone tools are usually the ones which everyone finds the easiest to start using because they give such immediate results. The Magic Wand works by selecting colours within the image adjacent and similar to any pixel that you click on. Pixels of dissimilar colour act as barriers to selection and so the selection ripples outwards from the point you click on.

As you can imagine, you will not normally completely select your intended subject with one click when you are using the magic wand to make selections. Typically, you will select part of the area that you want and you will then need to add and subtract from the selection, perhaps switching to the other selection tools from time to time. Photoshop offers you two ways of modifying a selection: you can either use modifier keys on you keyboard or activate the modifier icons on the options panel normally displayed below your menu bar.

To add more pixels to your selection, hold down the Shift key while clicking with the Magic Wand on a part of the image which is not yet selected. To subtract from the selection, hold down the Alt key and click on the part of the selection which you wish to deselect. The selection modifier icons are situated on the left of the options panel. There are four of them: new selection, add to selection, subtract from selection and select intersection. These icons effectively allow you to change selection mode on a permanent basis. Thus, for example, you could click on the second of the four icons when using the Magic Wand and click continually on different parts of a subject until it was completely selected.

If you want to select a subject against a uniform background such as a wall or the sky, a simple trick is to use the magic wand to select the background and then invert the selection by choosing Select – Inverse. A slight variation on this technique is to make a rough selection which completely encloses the subject as well some of the background and then to use the Magic Wand in subtract mode to remove the background from the selection.

You can control the number of pixels which the Magic Wand selects when you click on part of the image by changing a setting called tolerance. Tolerance determines how far a pixel can vary from the pixel that you click on and still be included in the selection. The default tolerance is 32 and the maximum is 255.
