What is a computer power supply? Also known as the PSU, it is the drive to provide power to the computer and its peripherals by converting alternating current (AC) to direct current (DC). In other words, turn the computer from the wall outlet.
Many people experience problems with the computer that seems to be caused by viruses, driver airbag, problems, software incompatibilities and other "guilty" when can a bad power supply, the currentCause!
We are talking about different signs of a bad or failing power supply:
Feels "strange" noises from the back of the computer come on tap
Your computer crashes (BSOD) randomly, observed no apparent reason, and crashed more often in games, movies, photo editing, etc.
The computer turns on, then shuts off immediately after boot without success.
When you restart the computer, often without apparent reason.
My powers of computers, butSometimes does not start correctly. This includes constant "Bad Checksum" may lack the boats.
They smell "burnt" smell coming from your computer. (This may mean burned or burning PSU-circuit)
The computer screen is strange "artifacts" such as pixelation, lines, colors or other optical effects do not belong on the screen. (This problem of feeding the video card)
Press the power button and nothing happens. The computer will not turn on, no lights, no fans spin … nothing.
The symptoms above are not the only signs of a bad computer power supplies. It is often difficult to determine the culprit a "problem" computer just accidental. Usually the best way to reduce a problem to a power source, is the exchange of hardware until the problem is solved. For most average computer users swapping components is not an option, but should be a better way! Or is there?
Yes, there!
Choosing the right performanceto avoid service in the beginning – a lot of headaches in the future, and we will show you how to get the other in a blog post. The care of their computer includes the maintenance of the electricity network and a computer power supply has a limited life span. We recommend the following steps:
1) Always use a surge protector.
Lighting, power cuts, nails, etc., can fail to expand its power when a voltage is not used toof all time.
2) Do you clean the feeder.
Help a can of compressed air and blow air through the rear of the PSU provide fans (see photo right). This will prevent dust, hair and other particles from collecting in your power to create the cooling and to prevent more heat, contributing to errors in the socket.
3) Make sure when your computer is well ventilated.
A major cause of failure of computer hardwareHEAT is. Heat is responsible for much of the computer failure to the power source and should be minimized. Make sure all fans are running on your computer, and the powder to collect in fins – interrupt the flow of air. Sometimes it helps to have a professional inspection of the computer to confirm adequate ventilation and "safe" temperatures.
4) Never buy "cheap computer" power!
A low-cost device is never usually worth the cost. Many people whoBuying a PSU after their failure, they decide to buy a device at low cost per unit to replace failed. Ballasts are computer cheap "in fact" lead to other computer hardware to fail first time.
** The specifications such as efficiency, amperage 12V rail, power, peak performance, the size of the fan, are all very important factors for buying the right computer power for the system. **
5) Depending on your ageComputer …
You can buy time for a new power. The power supplies have a certain amount of life-hours, and eventually fails. When will your power supply is the problem. Better for longer and more expensive power supplies may actually survive computer (S). Generic or "cheap" power are often unpredictable and can fail at any time between the date on which they are produced and sold until some years later.
If you have any of thesePSU problem symptoms listed, you have your computer checked by a professional. Many mediocre power and destroy the motherboard, CPU and other hardware at the same time.
I hope you are now armed with the knowledge to maintain the supply of computer power, so that the computer has more "up-time, instead of" avoidable downtime. Until next time ….. Happy computing!
