PC Computers are prone to errors because it has to "be" compatible with virtually everything. And sometimes thing do go wrong after a new hardware installation, driver installation, program installation or even an windows update. While most bluescreens (of death) are caused by out-of-system-memory, some are unique and can take a lot of time to fix. Below are the steps you should follow of first "Knowing the Enemy"
Well first do your computer restart immediately after the bluescreen? if so, When it restarts you should press F4 and chose "disable automatic restart upon system failure" or something of that sort, so you will have time to read the messages...
When the bluescreen of death shows up again, copy down the error code (number/letters following the "STOP" row, it should be 0x000000....). There should also be a brief summary of the cause of the bluescreen.
So as I stated chances are the bluescreen of death is caused by memory such as out of memory or error in reading/writing in memory blocks. But if that's not the case you should post your error code up here and I'll see if I can help you. Or visit http://support.microsoft.com/ and type in your error code on the search bar to see if there are any specific solution to your problem.
*Common Solution to Out-of-Memory.
This can happen when the program is using too much memory at one time and exceeds the system's memory & page files size (Or Page Files could not be accessed fast enough). Let say a program's minimal requirement is 1024MB of memory but you only have 512MB, chances are you will get a bluescreen in the middle of using the program of it fails to start in the first place. To address this problem is either you should look for other similar program that ultilizes less system resources or it is time to upgrade your system memory (See My "How can I upgrade my memory" Post for details)
Another reason of Out-of-Memory might be the program is actually malfunctioning or a virus/trojan is buffer-overflowing your system. Although most Anti-Virus Programs offer Buffer-Overflowing protection against such viruses, an nasty viral infection on your PC can write numerous unidentified scripts to actually overflow and crash your Anti-Virus Programs along with your PC, if that ever happens and you have followed all the diagnostic steps above, consult a GeekSquad in your local BestBuy store...(lol...though sale, but really you should see a professional in fixing your PC)

[Computer Networking] What is the difference between a Router & a Adapter?
In Computer Networking, Router have the function of an Adapter, but a Router perform more duties than an Adapter.
Adapter enable a computer to "Adapt" to the current network setting set by the "Router", Router also adapts the network settings set by the modem or sometime by the computer.
Yet there is a crucial difference between an Adapter & Router. I can demonstrate the simple difference of adapters & routers in wireless networks. Most Laptops have Wireless Network Adapter, not routers, because it can only connect to one network point (A Wireless Network Router or another computer). But routers can connect to multiple computers or act as a network point for multiple devices, so the almost all the Internet-Sharing "box-thingie" we have in home is named Wireless Network "Router", not adapter.

[System Memory] What is the difference between DDR2 memory and DDR3 memory?
The current industry standard is DDR2 memory running at from 667MHz to 800MHz. But there are upper class laptops such as the Apple's Macbook Pro series that utilizes a DDR3 class memory which currently clocks/runs at 1066MHz. A DDR3 memory generally runs faster than DDR2 memory and can achieve a wider bandwidth (Think of a wider freeway with a higher speed limit).
Expanding on this topic: Is DDR3 class memory really better than DDR2 class memory?
Comparing a 800MHz with the 1066MHz memory, as an End-user you might not notice the 266MHz increase in computing speed. In fact there is not much gain in performance (up to 3% gain) comparing the 800MHz memory with 1066MHz memory of the same size.
The 3% performance increase definitely varies by usage, most day-to-day stuff that you might do (such as Hulu or browsing your photo libary) will only takes advantage of the memory size other than the memory speed. And I can't think of one that only takes advantage of the memory speed.
Applications that are intensive on size: Streaming videos online or burning a DVD
Applications that are intensive on speed & size: High-End gaming that requires fast graphic rendering, research and 3D-Modeling.
Conclusion:
If you like gaming, it is obviously that a faster clocked and a larger memory can improve your computing performance. But comparing DDR2 class memory with DDR3 class memory of the same size there is a very little advantage and is probably not worth the marginal cost (If the sales told you "DDR3 class memory has a big advantage over DDR2 class memory") I recommend to look for a computer with a larger sized memory other than a faster clocked memory because in general DDR3 memory cost more than DDR2 memory.

), that electronic book has created the electronic book revolution. We can now enjoy our favorite titles without buying the actual prints, saving the planet's precious trees and our eco-system in the long run. Now with its latest generation we can save so many pieces of paper and raw printing materials because it can hold more than 200 titles, more than anyone can carry out if they were paper prints.
