assemble a tall pc, just like 10 years ago when a lot of people love a mainframe that is almost extinct. In this post-terminal era. Buy a small board that can carry Linux may be a good idea, it consumes less power, no noise, small, anywhere can be plugged in, long-term boot also does not matter, it is to do the best choice of home internet agent.Colleagues bought a small board like this, it is said to be very good. What do you need to do now when you

1, CPU fan If you hear a buzzing sound, it is estimated that the power of the CPU fan sound, because the fan used too long, the internal accumulation point of dust will appear some small hum. Generally open the cover to clean the fan can be resolved. can also add some lubricating oil, but not familiar with the computer can not be free to refuel oh. 2, the line was collided If you hear a sound that has a squeaky squeak, it may be that many times the power cord or the CPU fan power cable and th

Malicious programs can use fan noise to steal data from physical isolation systems Computer physical isolation does not mean that the data in the data can be carefree. Many studies have shown that electromagnetic radiation and heat radiation can be used to steal data from physical isolation systems. Researchers at Ben-Gurion University in Israel have created a malicious Fansmitter that can use a fan on an infected host to send stolen data. All data i

This is actually the Fibonacci sequence, but I started with DP, but I should think about it.An array of dp[i][2],dp[i][0] represents the number of the last number of the first I number is 0, dp[i][1] represents the number of the first I number inside the last digit is 1, I know dp[i][1]+dp[i][0] is the number of the first I can form a sequence.Here because can not 2 1 together, so:Dp[i][0] = dp[i-1][0]+dp[i-1][1]DP[I][1] = dp[i-1][0]#include POJ Dynamic planning DP-1953 World Cup

Win7 System playback video has been a noise impact watch how to solve? The workaround is as follows: 1. Press "Win+r" at the same time to open the Run window, enter "regedit" in the Run box and click Enter; 2, into the Registry Editor window, in turn, expand the "hkey_local_machinesystemcurrentcontrolsetservicesaudiosrv"; 3, in the right window to find and double-click the "DependOnService", in the pop-up window to remove

The filter was once seen on the playing with fire website, as described in the following: http://www.playingwithfire.com/dazzle/buttons.html But the metal plate is a well made style, style download package See this: Http://www.playingwithfire.com/dazzle/styles.ZIP Nothing can be edited in the FW except for the gradient direction. So the delicate metal surface version of the texture effect fireworks itself can be achieved? The answer is yes. Let's take a look at this effect chart first: The

I would like to give you a detailed explanation of the number of noise detected by the Canon 600D camera and the ISO sensitivity.Analysis and sharing:Select an ISO sensitivity value and a high ISO sensitivity noise reduction function, and press the "OK" button to display the noise produced in this combination. You can select different combinations for c

This information and technique is rarely shared on the web, but many people may need it. Share the experience here. This is also a problem that has plagued me for a long time. Because I bought this adapter, I found that when I recorded it, the iphone's headphone microphone had a lot of noise that could not be eliminated.First of all, this adapter has been sold in a certain Amoy net. The main point here is how to set up a sound card driver. Do not use

Many people are very concerned about their computer graphics configuration, especially boys, the requirements of the game configuration is obviously more than the general need to configure the requirements of the Internet. But recently, some users reflect the Win7 system Nvidia video card fan speed abnormal, noise, especially when playing games, to the normal use of the computer caused the impact. What is the cause of this? Small series first to hint:
