writer : DVD-RW LG
cooler CPU : Zalman 1500 Led
coolers : 3x120 Zalman
monitor : 246WH LG
keyboard : Microsoft Curve 30W
mouse : Logitech MX Revolutionthe price is nt bad but the processor is abit slower n should hav a bigger HDD size
i'm now trying configure out some desktop at the cheapest cost n at the fastest speed
thus, at below S$1500 u should gt:
1. Intel core 2 quad Q8300 processor (slower clock speed n cache but faster FSB)
2. Windows Vista Home premium 64 bit
3. 4GB - 8GB DDR2 677/800 MHz RAM
4. 640GB - 1TB HDD
5. ATI radeon HD 4770 graphic card
6. 22" LCD monitor
7. ...
but overall the desktop that u hav configure out is pretty goodBuy Corsair Memory Coolers at Auction Today

A Shorted Turn occurs when one transformer winding is electrically connected to an adjacent winding. It can occur in a Primary or Secondary Transformer winding. The most common cause for this type of failure is due to overheating of the windings. This causes the wires enamel to soften, then eventually breakdown and short. Internal Arcing can also cause breakdown of the wires enamel however this is more common when High voltages are involved. Also, any type of mechanical stress (as a result of a drop, and others) can be the reason behind this. For example, when two windings are pinched and damaged due to forceful contact with the Transformer laminations (core).
Some Technicians and Electronic Engineers are under the impression that a Shorted Turn can simply be ignored as all that it does is reduce the Transformers Turns Ratio, and thus the resultant output voltage. Nothing could be further from the truth! Simply put, a Shorted Turn appears as another Secondary Winding. However, this one is loaded with a zero Ohm short. Even though there may be only a few Milli-volts developed in this Secondary Winding the short requires infinite Current. The Primary Winding of the Transformer must provide this. Therefore, a Transformer with a Shorted Turn becomes totally unusable. Whenever a Voltage is applied to the Transformers primary winding the input fuse or Circuit Breaker will blow no matter how high the Amperage rating.
Large Power Transformers, Stators, and EHT Transformers all have hundreds of windings that make the determination of a shorted turn extremely difficult using conventional resistance measurements utilizing a DVM (Digital-Volt-Meter) or VOM (Volt-Ohm-Meter). A Milli-Ohm-Meter can be used to detect a Shorted Turn if the Transformers winding resistance is known prior to the occurrence of the fault. I.e. a Shorted Turn would be determined by a slightly lower winding resistance. This may be a resistance change of only a few Milli-ohms. It is also imperative that the Test Leads are precisely nulled (balanced) out of the measurement. Use of a Four Wire Instrument is the best way of achieving this.
A more advanced Test method involves applying a narrow pulse and analyzing the response characteristics. A normal Transformer will exhibit ringing on the rising and falling edges of the pulse. The ringing consists of several decaying oscillations at a frequency that is many times greater than the applied pulse frequency. If thought of in terms of the Frequency Domain these oscillations appear as Spurs (Spurious Emissions). A Transformer with a Shorted Turn will exhibit dampened Spurs (fewer oscillations with lower amplitude). Specialized Test Equipment is required to detect a Shorted Turn utilizing this Test method.
