It is hardware or software which protects a private network or a single computer. What basically does is it limits the access to or from that network resulting in greater security.

Jump drive is a plug-and-play device, if you have Windows XP you can simply plug it into your USB port and start using it straight away. As soon as it is plugged you can access it trough My Computer or Windows Explorer just like any other drive.

There is a small speaker inside your box - you can remove it or unplug the little cable that is plugged in. Although this may sound a bit drastic I still think it is the best way to deal with the annoying beeping problem.

If you don’t want to go that route this is what you should do:
Open Control Panel -> Sounds and Audio Devices -> click the Sounds tab -> from the drop-down menu of Sounds Scheme choose No Sounds.

The AGP video cards are generally a lot faster than the PCI video cards, which is partially due to the fact that the AGP bus is more advanced than the PCI.

If your mouse is connected to a usb port, unplug it, plug it back in and see it this fixes the problem. If you have ps2 mouse then you have to reboot. If nether of these fixes the mouse, you can take a look at it and see if there’s no dust or anything else underneath (laser mice) or open it, and clean it (older models).

The Celeron processor is cheaper than Pentium processor but it is slower too.

To get most out of defragmenting your hard drive:

- empty your recycle bin
- delete the temporary internet files
- run a registry clean

and only then defragment the hard drive. All versions of Windows have defragmenting tools, to open the disk defragmenter in Windows XP go to:

Start –> Programs –> Accessories –> System Tools –> Disk Defragmenter

Select the drive you want and click the Defrag button.

Although a zip drive looks like a floppy drive it can store much more data, the reason being is that Zip drives have higher quality magnetic coating and smaller head than the floppy drives.

SDRAM stands for Synchronous Data Random Access Memory. It synchronises to the pc bus speed.

DDR SDRAM is Double Data RAte Synchronous Data Random Access Memory. DDR SDRAM can be accessed by the system on both the upside & downside of a clock cycle. Standard SDRAM can only be accessed on the upside of a clock cycle. The 2 types of RAM are not compatible, your system will use one or the other.

If you have open slot then you can put another memory stick, I would recommend always using identical memory sticks (from the same manufacturer) - that way you can avoid running into problems.

To ‘install’ the new memory simply switch your PC off, unplug it, open the box, and insert the memory stick into the memory slot. Close the PC, start it, and you’re done.

You need to replace your motherboard’s battery - that will sove your problem.

If your screen is merely dusty take a soft cloth and simply wipe it, otherwise use soft cloth with a little bit of warm water - wipe the screen form one side to the other starting a new row each time.

Alternatively you can go to a computer shop and buy a product that will essentially do the same job ;)

Yes, of course. If your drives are named C and D, and Windows is installed on your C drive then you can format your D drive from Windows -> right click the D drive in Windows Explorer and choose format from the pop-up menu.

If Windows is installed on the same drive that you wish to format then you have to do that from a DOS prompt -> type format C: (of C is the drive) and press ENTER.

WARNING - formatting a hard drive will delete all your files and programs!!!!

Optical mouse will do just fine for most of your needs, if you need a mouse with extremely high precision though (e.g. if you an architect, graphic designer etc) only then you should consider buying the more expensive laser mouse.

This can be hardware (most likely) or software related. To make sure reboot your computer in safe mode and see if the problem persists. If it does you can be 99% sure that you have bad ardware. Try the following steps to resolve the problem:

Check your power supply - it is the most likely culprit, if you power supply is bad you’ll have to replace it.

Faulty video card - remove your video card and see if your computer shuts off again. If it doesn’t then your video card is faulty. Try downloading the latest drivers and see if that fixes it, otherwise replace it.

Cpu overheating - clean your CPU fan, and check if it works properly, if it doesn’t then simply replace it.

Bad RAM - if you have two (or more) RAM chips in your PC remove them one by one and see if the problem persists. IF your RAM is bad you’ll have to buy a new one.

Spyware, viruses - update your anti-virus software and run complete check on your PC, download Spybot - Search & Destroy and check your computer for spyware.

Hope that helps
