- - the voltmeter;
- - screwdriver;
- - the clip.
Do not open unit the powerto find it faulty. It is up to the experts. To determine the malfunction of this critical component, do not have to disassemble the system unit. Be careful to work your computer.
Remember whether frequent restarts and freezes for no apparent reason (during execution by the computer for simple tasks). Note the appearance of bugs in programs and operating systems in General. Errors in the functioning of the memory during testing and during further work in the system. Disruptions in the hard disk or the failure of the past, talking about the disappearance of the voltage output block supply.
Note the odor and excessive heating of the system unit. It is an undoubted symptom of the unit power supply of your computer.
If the computer does not submit signs of life, you have to take it apart. Disconnect power from the system unit. Grab a screwdriver. Remove the screws that hold the right wall from you system unit. Remove the cover to access the motherboard.
From the slot of the motherboard, remove the main plug connector unit power supply, which has 20 or 24 pins. Find the third and fourth contacts, they are green and black wires. Short the two contacts using a regular paper clip. Connect the cable of power supply. In good block power supply this starts the fan, and its terminal voltage will be.
Measure the voltage with a voltmeter. Between terminals black and red wires it will be 5 volts, black and yellow - 12 volt, black and orange - 3.3 volts (minus the black and color plus). If the values you obtain are different from the above - your power supply is faulty.
Advice 2 : How to determine the capacity of the computer
Many users are concerned, "powerful" is their computer. The main difficulty is that in different tasks, the computer demonstrates the different performance and numerical expressions "power computer", in General, no. There are a huge number of test programs that define the ability of a computer to carry out certain tasks, with varying degrees of specialization.

The closest to creating a single evaluation scale was approached by the company Microsoft. In the latest versions of their operating systems has such a feature, as assessment of the performance of the computer. To use this function, activate the tab "Computer" in the start menu". In the window that appears, select the menu item "system Properties". Find the line "Score", which displays a figure. This is the assessment of the performance of the computer. Clicking on the hyperlink "Windows experience Index" next to it, you can learn what the components of the sum score. The lack of this assessment in its very low precision and low information content.
Other methods of determining the "power" of the computer is focused on certain types of applications. One of the most popular benchmark, 3DMark, determines mainly the performance of computer games. To learn "gaming evaluation" of your computer, install 3DMark and run the standard test. You will receive a number of points, which will display the power of computer games. Compare your result with others on the Internet.
The computational power of the computer is determined using other test programs, one of which is the PassMark. After executing it you will get a rating of the CPU, also in points. On the website of the developer collected a huge statistics of these tests and you will be able to compare your results with the ratings from other users.
The Internet has long walks already rather overgrown beard instructions on how to determine the gender of your computer. To determine your computer man or woman, open Notepad and copy without external quotation marks following text: CreateObject("SAPI.SpVoice").Speak"I love you"".
In order to find out what sex the computer you have, you need prodelat very prostoru operation: 1) Open Notepad. 2) Copy this phrase - CreateObject("SAPI.SpVoice").Speak"I love you". In General, GetVoices returns the voice that comes preinstalled on the system. Using search, you can sort out the voices and to choose, if the existing floor of the computer you are not satisfied.
Advice 3 : How to check the power supply of the computer
Power block power is a very important feature of a computer, which is designed to ensure the uninterrupted and proper functioning. The higher it is, the better. But there is a minimum value that must match the specifications of the computer.
The more powerful "stuffing" of the computer, the stronger the need the power supply. Usually, the manufacturer says, power on the unit on a sticker. To find out the required power there are various online services. ASUS on its website has the appropriate form to fill and the program will display the desired value on the basis of the maximum possible power consumption of the computer components.
Go to the service page. Motheboard in field, select Desktop (if you are using a home desktop) or Server (if testing is performed for the server).
In the CPU tab, specify the settings the manufacturer of your processor. In the "Select Vendor" to specify the engine's manufacturer, CPU Type select the CPU family, and in the "Select CPU", specify the model itself.
In the VGA Card section, specify the values for the video card in the computer, where the Vendor - manufacturer of ATI or Nvidia, and in the "Select VGA" indicates the model of the video card, which you can see in the control panel driver Board (the right key on "My computer" - "Properties" - "device Manager - "display Adapters").
In the Memory Module, specify the type of memory (DDR, DDRII, DDRIII).
From the Storage menu, specify the number of Devices connected to the computer device for recording and reading. In the USB section, specify the connected USB devices. In paragraph 1394 note the additional charges for video capture, and select an existing PCI device (Modem, Network (LAN), Audio, and other PCI card - number of network devices and sound cards connected to the PCI slot in the motherboard and SCSI card – number of cards to connect SCSI bridge).
The program will automatically give the optimal value, which must be indicated on the sticker of the power supply. Otherwise, the unit should be replaced by a more powerful service computer repair.
