You have just been struck by the Blue Screen of Death. Anyone who uses Mcft Windows will be familiar with this. What can you do? More importantly, how can you prevent it happening?

1 Hardware conflict

The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices through an interrupt request channel (IRQ). These are supposed to be unique for each device.

For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ 6. Each device will try to hog a single IRQ for itself.

If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number. When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a hardware conflict is through the following route:

How To Create A Dot Plot In Microsoft Office Excel

Fig 1. A Horizontal Dot Plot

A horizontal dot plot is probably the easiest type to create. Just list the category labels in column A. Then in column B enter the corresponding numbers. To create the dots for the dot chart in column C enter the formula =REPT("•",B1) or =REPT(CHAR(149),B1) and then copy the formula down. Then, hide column B. Pretty simple, eh?..

67 WINDOWS 7 HIDDEN TIPS & TRICKS

1. Problem Steps Recorder
As the local PC guru you're probably very used to friends and family asking for help with their computer problems, yet having no idea how to clearly describe what's going on. It's frustrating, but Microsoft feels your pain, and Windows 7 will include an excellent new solution in the Problem Steps Recorder.

When any app starts misbehaving under Windows 7 then all your friends need do is click Start, type PSR and press Enter, then click Start Record. If they then work through whatever they're doing then the Problem Steps Recorder will record every click and keypress, take screen grabs, and package everything up into a single zipped MHTML file when they're finished, ready for emailing to you. It's quick, easy and effective, and will save you hours of troubleshooting time.

2. Burn images
Windows 7 finally introduces a feature that other operating systems have had for years - the ability to burn ISO images to CDs or DVDs. And it couldn't be much easier to use. Just double-click the ISO image, choose the drive with the blank disc, click Burn and watch as your disc is created.

3. Create and mount VHD files
Microsoft's Virtual PC creates its virtual machine hard drives in VHD files, and Windows 7 can now mount these directly so you can access them in the host system. Click Start, type diskmgmt.msc and press Enter, then click Action > Attach VHD and choose the file you'd like to mount. It will then appear as a virtual drive in Explorer and can be accessed, copied or written just like any other drive.

Click Action > Create VHD and you can now create a new virtual drive of your own (right-click it, select Initialise Disk, and after it's set up right-click the unallocated space and select New Simple Volume to set this up). Again, you'll be left with a virtual drive that behaves just like any other, where you can drag and drop files, install programs, test partitioning software or do whatever you like. But it's actually just this VHD file on your real hard drive which you can easily back up or share with others. Right-click the disk (that's the left-hand label that says "Disk 2" or whatever) and select Detach VHD to remove it.

The command line DISKPART utility has also been upgraded with tools to detach a VHD file, and an EXPAND command to increase a virtual disk's maximum size. Don't play around with this unless you know what you're doing, though - it's all too easy to trash your system.

4. Troubleshoot problems
If some part of Windows 7 is behaving strangely, and you don't know why, then click Control Panel > Find and fix problems (or 'Troubleshooting') to access the new troubleshooting packs. These are simple wizards that will resolve common problems, check your settings, clean up your system and more.

5. Startup repair
If you've downloaded Windows 7 (and even if you haven't) it's a good idea to create a system repair disc straight away in case you run into problems booting the OS later on. Click Start > Maintenance > Create a System Repair Disc, and let Windows 7 build a bootable emergency disc. If the worst does happen then it could be the only way to get your PC running again.

6. Take control
Tired of the kids installing dubious software or running applications you'd rather they left alone? AppLocker is a new Windows 7 feature that ensures users can only run the programs you specify. Don't worry, that's easier to set up than it sounds: you can create a rule to allow everything signed by a particular publisher, so choose Microsoft, say, and that one rule will let you run all signed Microsoft applications. Launch GPEDIT.MSC and go to Computer Configuration > Windows Settings > Security Settings > Application Control Policies > AppLocker to get a feel for how this works.

7. Calculate more
At first glance the Windows 7 calculator looks just like Vista's version, but explore the Mode menu and you'll see powerful new Statistics and Programmer views. And if you're clueless about bitwise manipulation, then try the Options menu instead. This offers many different unit conversions (length, weight, volume and more), date calculations (how many days between two dates?), and spreadsheet-type templates to help you calculate vehicle mileage, mortgage rates and more.

Don't take any Windows 7 applet at face value, then - there are some very powerful new features hidden in the background. Be sure to explore every option in all Windows applets to ensure you don't miss anything important.

Different Types of Computer Viruses

There are a multitude of different types of computer viruses; the usual suspects that come to mind are 'file infecting' viruses, Worms and Trojans. All computer viruses and even real genetic viruses that infect our bodies have one sole purpose - to replicate!

For some computer viruses this is their only mission, but often they have intent to cause severe harm and total destruction. Although some viruses are known to do little harm - they should never be deemed harmless.

File Infectors (aka a virus)

More commonly known to you as a virus, file infectors are the backbone to the majority of virus adaptations that are out there. A file infector is run or 'awoken' by an executable file (.exe) being run, either by the user or a program the user is using. Once launched, the virus begins its tasks that were given to it by the coder.

Trojans or Trojan Horses
