Question about Dell Dimension 4600 PC Desktop
Cooling fans do not start?
Does this include the Power Supply fan also?
Does the LED Power On light light up? How about the Harddrive activity LED light?
So far from your brief diagnosis given, it would seem you have a bad Power Supply. Weak voltage power rail.
1) ALL the LED lights use less than 1 Watt of power.
2) EACH fan uses 2 to 3 Watts of power.
3) A typical Processor can use 51 to 125 Watts of power. Depends on what Processor it is.
[The Dell Dimension 4600 desktop computers, were offered with a few different models of Intel Pentium 4 processors.
Intel Pentium 4 at 2.26GHz, up to an Intel Pentium 4 at 3.06GHz.
(Left-click on Technical Specifications in the list)
These Intel Pentium 4's can use anywhere from 56 Watts, up to 81.8 Watts.
(56 Watts for an Intel Pentium 4 with a Northwood Core at 2.26GHz, and 81.8 Watts for an Intel Pentium 4 with a Northwood Core, at 3.06GHz. Look under TDP)
A bad Power Supply with a weak voltage rail, may have enough power to light LED lights, and maybe even spin fans, but will not have enough power to turn the Processor on.
Suggest you look into the Power Supply.
