I then bought a new motherboard, took out the graphics card, ram, hdd etc ( so just left the cpu and cpu fan ) but the new PSU burnt within 30 seconds.

When you identify the culprit, take a look at its specifications ( CPU fans are designed for the CPU socket they're attached to, for instance ) and shop around for a quieter one ( manufacturers give noise ratings, these could be an indication ).

Yes, there is a microcontroller inside most chipsets, which takes care of some very basic functions ( it's the thing that handles wake-on-lan, and that beeps when the CPU isn't installed or the CPU fan isn't working ).

It can be anything, including bad CPU fan, bad memory, bad power supply, a large number of other potential hardware problems, and a broken Windows installation, which can be caused by normal cruft acumulation, a cesarb 22 : 36, 15 January 2006 ( UTC)

My previous old computer only had a power-unit fan and a CPU fan as far as I recall, and worked OK . The current temperatures are Motherboard 34 degrees C, CPU 27 or 28 degrees C, HDD 26 degrees C, fanin0 2812rpm, and fanin1 3125rpm.

Then make sure that the CPU fan is correctly connected to the appropriate header on the motherboard-most motherboard microcontrollers will refuse to let the system boot if they don't detect the fan ( as a missing or bad fan would result in the CPU being very quickly cooked alive ).

A permanent solution may involve a more powerful case fan and / or CPU fan, or changes to the software, if the fan isn't coming on soon enough, or ensuring that any heat sinks are properly attached . talk ) 17 : 51, 5 July 2012 ( UTC)
