You can upgrade Alienware desktops because of its many expansion slots.
Absolutely! Almost all desktop components are able to be replaced.
The site to go to is http://www.alienware.com/. I would be careful though. Alienware computers are very cool, and usually top of the line... however, they are ALSO extremely expensive. You might be able to get something comparable for less at a different site. You definitely have to pay for the Alien. :)
You may not be able to upgrade because certain components in your old computer may not be compatiable to some of the new components in a new computer.I would suggest buying a new computer,basic then upgrade how you like.
No the Able Sisters do not upgrade.
In general laptops are not easy to upgrade. You MAY be able to add more RAM, but some laptops are sold with the maximum RAM they can handle already installed. You probably cannot upgrade the CPU, but you can't necessarily upgrade the CPU in a desktop without replacing the motherboard.The only upgrade that you can almost certainly make is to increase the size of the hard drive.
If you are unsure, there is a company called Overclockers who will build a gaming PC for you from individual components, or allow you to select a pre-built desktop PC. This means you are able to see exactly what goes into the PC, and exactly what you are getting for your money.
Not much. Motherboards are tightly integrated, and you can't really upgrade the built-in components; that's what expansion slots are for. If you possess sufficient soldering skills, you may be able to replace bad components like capacitors.
In Bermuda, Niagara and Mu stages, you can get upgrade from Gyro.Bermuda - Upgrade for cane swing (you will be able to break most of the blocks with the cane swing)Niagara - Upgrade for Pogo jump (you will be able to break most of the blocks with the Pogo jump)Mu - Upgrade for pulling (you will be able to pull multiple blocks)
No.
For a Mac computer you can get Deskshade online by just putting it in on google and it will enable you to be able to change your desktop. In XP, you should be able to navigate to the picture and select "Set as desktop background" from the file menu.
Yes
A traditional desktop computer usually has a computer tower, monitor, mouse, and keyboard. An all-in-one desktop, however, tries to combine these. The actual computer will be inside of the (sometimes over-sided) monitor, and the monitor itself may include a touchscreen. You will still usually want a keyboard, rather that trying to use the on-screen one, and a mouse my be useful as well. You will at least be able to do away with the computer tower, however.
