I have been having some problems with getting my computer to turn on when I want it to. When I put my computer on sometimes it will start but wont let me turn it back on again the same day and I would have to wait for the next day to turn it on. But some days it wouldn't start at all.


When I put the plug on and check the power light at the back of the computer the green light would be on and when I press the power button I hear a slight noise maybe the fan? I'm not sure! Then it would not start and when I check the green light at the back and it has gone off.


I have checked all the wires at the back of the computer they were all fine and even vacuumed all the dust away inside , but still have the same problem.


Can anyone please give me any information on what the problem could be.


Thank you ^^

It could be the on/off switch, the power supply or problem with the mainboard/cards.


From what you describe though it sounds like you need a new power supply.  They are pretty easy to install if you feel up to it.

I second the power supply, but would check the two main connectors from the PSU to the motherboard, the big 20-24 pin one and the 4 pin connector that plugs in near the CPU.

If either one of them is loose, it can cause those symptoms.

If you reseat them and it still happens, it almost sure to be your PSU.

All is well in Paradise.

Thank you for your replies^^


I shall try to reseat the wires if it doesn't work I'll have to get a new PSU. I'll let you know if it works.
