    Maybe you mean you could hear the fan? And the light is coming from the switch button of the desktop?

    Can you hear beeping sounds when you try to switch on your computer? If that's the case? How many beeps do you hear?



    Can you please check the Device Manager for me? See if there are yellow exclamation point next to the Hardware. You can find it by pressing Start ---> right-click My Computer and choose Manage and Under System Tools.

I would unplug the dell for a couple of minutes. Plug it back in and then see if it comes on. Sometimes dells go into a sleep mode and are hard to wake. If the pc is 5 years or older think about a new machine. Hope this helps.

Before performing anything on the motherboard try to verify if the power supply is working properly, sometimes this is the first symptom of a failure power supply.

Is the power button orange, it's most likely a motherboard failure.

You can fix it yourself. The CPU was to hot and the solder has come off. Bad part is the solder is under the CPU and must be heated up. It is lead free so it needs more heat then lead and you need to add flux. I would start by getting the board out. Remove the thermal paste off the CPU. Add flux with a flux pen. You want to get the flux under the CPU so you might want to tip it on its side. After you have a good amount of flux under the CPU you want to start to heat the parts around the CPU. I would use a heat gun with temp. settings. You first want to heat around the CPU to keep solder on the other parts from cracking. You dont want to over heat the parts. After you preheat the board you want to heat the CPU. It needs to be around 400 or 500 degs f. a good 15 or 30 sec. keep moving the heat gun. After heating the CPU you want to start the cool down. Same as warming up the board but you want the board to cool down slow. After all this you want to add New thermal paste to the CPU. This helps transfer from the CPU. This is a must because your PS3 is overheating as it is. After you do all this some people say it only works for 2 to 6 weeks. Its all on how you fix the board and how good of a job you did. I would back up your hard drive. Then hope for the best!! good luck and i hope this helps you out.

Could a faulty fan cause my pc not to switch on


Normally the computer will still come on even if the fan is not there but then will sometime display cpu fan warning and then sometimes turn off depending on motherboard and so on but unless the fan wires are shorted out or something this is most likely not the case

It sounds like your power supply has gone bad
Do you hear any type of winning sound or like a discharge sound that is barely noticeable when you turn it on? You would probably almost have to put your ear right next to it to hear it or listen carefully when you press power because that sound is one of the capacitors in the power supply that has gone bad and the power supply would need to be replaced

Do you have another power supply you can use to see if it works with a different one?
