Not sure based on what youve written, but my first guess would be a bad power supply. try another PSU or provide more info.

SOURCE: Dell Dimension 4500 has been working fine but

The problem with your Dell Dimension 4500 is that its power pack (the device that supplies power to the mother board) is bad. The only solution is to replace it (Though sometimes it could be fixed, my recommendation is get a new one, the price to fix and getting a new one are about the same anyway). To do this you need technical support unless you are a technical person. The fact is it is a very simple procedure. But to be sure that nothing goes wrong or another complication doesn’t arise you need a technical person to change the power pack. However, if you a technical person and you are sure this your comfort zone, follow this procedure:-
Open up the CPU casing. Unscrew the power pack (this is the device you plug in your power cable from the back of the CPU). Take it to any computer accessories store and purchase one with the exact power specifications. Return it to your CPU, screw it back and plug in to your board and devices. 
Power on the System.

SOURCE: my dell xps420 does not turn on, no switch power or light, i have working internal lights

there're a couple of reasons for this.. maybe the motherboard and the new power supply is incompatible.

try removing the power cables for all the drives, just leaving the graphics card and ram seated. see if you can get into the bios. if you can, means the power supply u used is not enough to power the drives.

otherwise, try removing a component at a time to see where is the problem. try to get to the bios and hear for beeps. they should be tell-tale signs.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electro-medical.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Intertek Tower Fan will not come on.


Oh I may know this one... if the fan is good, chances are you have a bios problem.in the boot up routine starting the fan is one of the first actions the system will do. You may need to reload the bios... also if that fixes the problem then you may want to look at the cmos batt.. it keeps voltage on the chip so that it will not loose memory. As far as I know there isno way to verify bios good, except by listening for the fan to come on, hard drive runs and lights flash.you can check the fan by putting power to the leads andsee if it runs.

Why heater fan will not come on?


Wish I knew how old your furnace is. Let me answer your question directly. In the heat mode the fan runs independently from the air conditioning fan relay. Its either brought on by time or temperature. An old furnace will use a fan and limit control that uses a coil to sense the heat exchanger temperature and turn the fan on or off. Newer furnaces use a timer on a circuit board. 20 years or newer Ill bet its a timer board. Follow the blower motor wires back to the component and ill bet that's the culprit. Hope it helps. Good luck.

Ruud troubleshooting


do you have the lower door in place tight ?? because there is a door button switch. so if its not pushed in all the way you would have no power at furnace. also make sure nobody turned off the on off service switch usually above furnace or sometimes one at top of stairs and one down by the furnace .if those suggestions don't work you might want to turn each breaker off then back on incase one is tripped. if that don't work check for 120 volt at your fan timer board also it may have a automotive style fuse on the board which if blown it wont do anything. if there is 120 volt at board and the 24 volt circuit fuse is good its probably the fan timer board.

Operation light flashes on three times and the timer light continuously flashes, the unit will not work


Please remove the power for few hours , push down all panel buttons to drain off residual voltage on the panel. It seems that the main processor has encountered an error due to many reasons and so it is best to start by resetting the processor.
If there is no result then the main output must be checked, the compressor, the pressure switch and the fan circuit must be checked. If there are errors in any of the motors the excessive load will not allow the motor to start but would show a trip as circuit break

Circulating fan is running continuously.


indicates that either the fan setting is on FAN or there is a error code stored in the circuit board. Look for a blinking light through a small viewing port in the front panel door.

I have a SELV electric fan in my bathroom with a timer. I want to be able to disconnect the timer portion so that the fan will switch off as I turn off the light.


OK .. the obvious connection would be to find the transformer. Then look at the imput and output of the transformer . you want to take the output , 24 volts, from the transformer and wire it directly to the lamp base. If this transformer is attached to the circuit board then it may be a difficult task to separate the leads. You will want to haqve the pull chain switch in the power line between the power source and the transformer , so the transformer is only working when the lamp is on.

My ceiling fan suddenly stopped working. It has a remote and 2 pull chains, and neither the light or the fan are working. Only button i see on side of fan is a slide button that controls direction of...


Did you notice if there was anything else not working in the house? If so, most likely a breaker tripped. If it did, then there is a problem with the circuit. Unplug everything on this circuit and try resetting the breaker. If it still has problems, call in a licensed electrician to troubleshoot the problem.
Did anyone work on anything prior to this event? May be a loose connection. turn off ALL the power in the electrical panel before you work on the fan because you have no idea which breaker (or fuse) operates this unit. Check all the connections in the fan. If the connections are good then we need to stop here because more details would be needed.

Fan running after car is turned off. car dies and wont start, but its getting power from battery


there is a fan timer module that runs the fan if the temperature is 194 or hotter. if the module,which has internal relays fails the fan will not shut off.if you want a cheap fix,wire a relay in series with one of the fan wires so that the relay only is activated by a source of switched power from the ignition..that relay will pull about 200 ma only,so wire the relay power to a circuit like a switched power outlet,lighter or other circuit with no computers on it to control the relay.the radio circuit switched power is a good one to use,and make sure to use a 25 amp relay ,as the fan pulls about 10 amps.a bosch 4 pin will work fine.
