Why are Both lights flashing on my huscn15?fan doesn't start either

Do you see anything on the screen? Does the HDD LED blink? You can start by removing the HDD and testing it or have it tested.

3 flashes could be the pressure switch ,jump it out see if it lights or clean the flame sensor or check the snap dice's 1 for high temp and 1 for low temp ..

the green light flashing on the backside is your internetconnection.
about the computer wan't start i should check the PSU do the fan movs any light on the motherboard.if not is the electric cord firmly and tight in place.if the fans runs and lights on the motherboard.you got no picture proberly brooken videocard.

What light, and how do you start it then it does not start ??

Sounds like the fan has stopped working if fan doesn't turn no air will blow through there is a censer if this gets 2 hot it will shut down so not 2 cause a fire it fails 2 safe the sorliton is a replacement fan motor.

Hope this helps

Power getting to the computer/Power Supply?
Yeah.

Power Supply good? -> NO

A) IF ALL of the LED lights were on at once, they would use less than 1 Watt of power.

B) EACH fan uses 2 to 3 Watts of power.

C) A typical Processor can use from 51 to 125 Watts of power.
Just depends on what Processor it is.

HP Pavilion a810n Desktop PC?
Uses an AMD Athlon 64 3300+ processor,
(Operates Up To a frequency rate of 2.4GHz)

http://en.wikipedia.org/wiki/List_of_amd_athlon_64_microprocessors#.22Newcastle.22_.28CG.2C_130_nm.29

Can use up to 89 Watts of power.

Your Power Supply doesn't even have enough power to spin fans, much less start the Processor.

Want to test the Power Supply? Have a multimeter?
No? Have a power supply you can borrow for a test unit?
KNOWN to be good, and Compatible?

have a look on the bottom of the case for access panels, remove these and check the fans for dust build up, even if the dust doesn't look too bad, its worth cleaning. Also try to remove the fan to check between that and the heatsink, dust can build up there very much. This could cause the fan to be innefficient so could be an overheating problem causing your shutdown.

If this happens while it is rotating, it is likely that the inside wiring has come loose from the connections and it makes temporary contact on rotation.

Do you have any check engine lights on? Is your anti-theft light flashing? If so, put key in igniton, turn to on (NOT START) leave in on position for EXACTLY 10 MINUTES
As SOON as theft light turns off, try to start.

There is a problem with your key.

I had my Optiplex GX520 at work shut down abruptly every time I turned it on it in the morning. This would always happen within the first 30 minutes. I would then get the flashing amber light. After starting the PC again, it would stay on all day (over 8 hours) without shutting down again. I found that the power supply was over-heating.

Two things need to be done. First, in order to get the amber light to stop flashing, un-plug the computer from the wall for 30 seconds then plug it back in. OR hold down the power button for 10 seconds or so. The light should stop flashing. Then press the power button again and the PC should start.

But why did it abruptly shut down in the first place? The power supply has a fan-speed-control circuit in it to keep it running slow and quiet when the power supply is cool. It gives the power supply lower voltage when the power supply is cold and higher voltage as the power supply gets warmer. This circuit either is not working correctly or the fan getting sticky over the years and needing more voltage to get it moving when it is cold. I found that the fan was not starting at all and causing the power supply to over-heat.


To keep the fan moving at full speed, I cut the wire to it and wired it to the +12v output directly. Not the fan goes at full speed all the time. And yes, it is nosier. But at work it doesn’t matter.

The best solution would be to just get another power supply from Dell if possible. Or buy a +12v, 70mm fan from Digi-Key and replace the original.
