Dell Tower won't turn on/boot - (inspiron 545)

Jump to solution

Hello my name is Sebastian Todd, I've been using my dell computer for more than 2 years now with absolutely no problems affecting it, due to my proper maintenance. About 1 month ago, I turned it off by clicking the "shut down" button. Ever since then, I haven't been able to turn it back on. When I push the power button on the tower, it emits a yellow/orange light for about a quarter of a second. I know for a fact that there is a sufficient power supply, due to the green light being emitted on the back of the tower. I don't know what to do, and am not economically ready to purchase a new computer. PLEASE HELP! (inspiron 545)

Does the power supply fan run/work?

The green light on the back of the power supply does not indicate that the power supply has not failed, it only indicates that power is reaching the PSU. 

What colour is the power button light, is it Blinking, Solid or Off?

Are there any 'Beeps'?

Hi, thank you for the response.

the fan starts up for a tenth of a second when i press the power button.

the power button flashes yellow for a split second as i press it.

There are no beeps.

 First tturn off the desktop, remove power cord and hold power button in for about three minutes, reconnect power cord and power system on and see if this makes a difference.

No difference, try the following, if you are comfortable working around computers:

Note: The only 100% method of testing a PSU, is to install a known working power supply.

Unplug the cord from the power supply, hold the power button in for about 15/20 seconds, open the case, unplug the 24-pin power connector from the motherboard and jump the Green wire to one of the Black wires, reconnect the power cord and power the system, if power supply and case fans and the hard drive run, then the PSU should be good.

Note: Do not remove any wires from the plug, use a small piece of wire or a paper clip as a jumper.

Power supply checks out, again disconnect the power cord, hold the power button in for several seconds to discharge the residue power, reconnect the 24-pin connector to the motherboard.

Remove all PCI cards from the system, take out the video card [if applicable], disconnect all peripherals, except the monitor, mouse and keyboard and disconnect the power & data cables from all drives. 

Reconnect the power cord and power system on, see if you get a different LED indication on the power button, or 'Beeps'.

No difference, remove the memory from the system and try again.

Still shows no signs of life then you are looking at a motherboard replacement & maybe a processor. 

Bev.

I carried out the first troubleshooting procedure, where i held the power button in for 3 minutes. The other procedures, i'm not going to do myself because I know I'm gonna mess something up. On top of it im confused with half of the stuff you told me to do. This has nothing to do with how you explained it, just that I'm completely lost.. and dont know how to do those procedures. Should i take it to someone to fix?

Yes, as you feel you not comfortable working around computers, I would respectfully suggest you take the computer to a trusted local computer repair shop.
