Computer Killers – Pet Hair, Dust and Cigarette Smoke | Technibble. As a computer technician, I have seen some pretty interesting computer problems. The majority of problems I encounter in the home market are adware, spyware or connectivity problems and the occasional hardware problem. The hardware problems are usually caused by simple manufacturer fault (as in, it was going to fail at one point anyway) or a power surge.
However, occasionally I find a computer that was killed by pet hair, dust or cigarette smoke. These three eventually find their way into the computers fans or heatsinks causing the computer to overheat and die. Over the years I have come across a few bad cases of this and I would love to share some of the photos with you. Warning: Some of these photos are pretty gross. I purposely kept them at a high resolution so you can see them in all their glory. Edit: Added other computer technicians pictures that they sent in Computer 1 A client brought in a laptop that kept restarting during bootup.
Computer 2. Causes of Power Failures & Power Outages. Electrical power, in the short span of two centuries, has become an indispensible part of modern day life. Our work, leisure, healthcare, economy, and livelihood depend on a constant supply of electrical power. Even a temporary stoppage of power can lead to relative chaos, monetary setbacks, and possible loss of life. Our cities live on electricity and without the customary supply from the power grid, pandemonium would break loose. Power outages can be especially disastrous when it comes to life-support systems in places like hospitals and nursing homes, or in co-ordination facilities such as in airports, train stations, and traffic control.
Fortunately, most life support facilities have a source of backup power that is ready to automatically take over should the main power grid fail. It is important to know about the possible causes of power failure in order to better protect ourselves and our businesses from its devastating effects. Why do short circuits occur?

A finned heatsink and fan clipped onto a microprocessor, with a smaller heatsink without fan in the background. A 3-fan heatsink mounted on a graphics card to maximize cooling efficiency of the GPU and surrounding components. Computer cooling is required to remove the waste heat produced by computer components, to keep components within permissible operating temperature limits.
Components that are susceptible to temporary malfunction or permanent failure if overheated include integrated circuits such as CPUs, chipset, graphics cards, and hard disk drives. Components are often designed to generate as little heat as possible, and computers and operating systems may be designed to reduce power consumption and consequent heating according to workload, but more heat may still be produced than can be removed without attention to cooling. Many computers are designed to sound an alarm or switch off if certain critical internal temperatures exceed a specified limit.
