Computer restarts itself everytime you download through the internet Tried all the suggested things that could fix this and none have worked help you please?

the 1st thing i think u should do is scan ur computer for virus or unwanted files using a recently updated antivirus. the antivirus on ur system may not be strong enough.if u use a demo version or outdated antivirus,it might scan but detect no virus or damaged files even if there are.

second thing to do is go to start on ur system, click all programs, click accessories and then system tools then system restore. click it and follow the instruction given to restore ur system to one of the highlighted date that corresponds to when ur system was faultless. it might be that ur system developed the fault as a result of trying to install or uninstal a software that is not really recquired eg netspeed booster software or the system accelerator software.

after these two steps, if ur problem persists, i advice u see an engineer, but I'm sure with these points, ur problems are solved.

3 main differences between a PC and a Laptop?

Here the three main differences between a PC and a laptop:

1. Size

A laptop is portable and can be carried easily, which is particularly useful if you want to move it between work and home. A PC, on the other hand, is stationary.

2. Parts/Repair

Fixing a laptop is far more troublesome than dealing with a desktop counterpart. You can't exactly order up an extra hard drive and attach it yourself. Laptops require professional installation. A desktop, on the other hand, can be added and modified as you please. Almost anyone can learn to add computer parts like video cards to a PC himself but it's virtually impossible on a laptop. Everything from adding memory to an extra USB port is just easier and user friendly on a desktop.

3. Storage

It's easier for a desktop computer to have a bigger memory and to hold more RAM than a laptop computer simply because there is more space available for the storage. The space in a desktop computer will often allow the user to choose almost unlimited accessories and options that a laptop computer just may not have the space to hold. Things like a top speed processor, the latest state of the art sound and graphics cards, extra ports for external linking and more than enough storage space for all of the programs, music and video clips that you'll ever need.

The extra space also comes with one more big benefit that you don't often find with a laptop - the ability to easily upgrade. This means that you can keep your machine from becoming obsolete for much longer by continually adding the latest programs, components and accessories.

Can a PC get a virus from streaming?

No, well not most of the time anyway. Streams are started by a person/company taking audio and video directly from their tv etc. and broadcasting it on the internet. So it would be extremely difficult for a person to get a virus from this. There are some streams though that load up spam on your pc. For example. Sopcast channel 11910. Everytime you load up channels, it loads up spam sites. But overall all MMS/RTSP/HTTP stream are perfectly safe. Hope this helps.

How does anti-piracy technology help to protect your software?

Strong anti-piracy solutions use robust encryption to make the software unusable until it's decrypted. Using much the same system as your bank or amazon.com uses to protect your credit card information, anti-piracy (also called copy protection) systems require a key to decrypt the software executable, allowing it to run when loaded into a computer's memory. The key is typically stored in a secure, secret location: either on a hardware device called a dongle, or in a file on the user's hard disk.
