I have a computer built by Centarus Computers.  It was working ok til about January 16th.  After it did an update install it was slower opening windows and doing certain tasks.  Then I noticed that if the power went out or if I shut it off to clean the fans off that it didn't want to start up again.  This happened off and on, but when it did it would take several days before it would finally turn back on.  I thought it was my power supply, so I just recently changed it out for a brand new one.  Now it won't turn on at all, it has been over a month since I changed out the psu and it still won't turn on.  I show my ethernet port is getting power since the light for it on my router is glowing green like it is supposed to.  If I unplug the comp from all power, then plug it back in, I push the power button to turn it on, I hear 1 small "click" and nothing happens.  If I push the power button again, nothing.  Not even that "click".  If I go through the whole unplug process again, THEN I get the "click" again, but only after I unplug & plug it each time!


Please, can somebody help me with any ideas?  I am afraid that it may be my motherboard, but would it still power my ethernet if it was bad?  I am hoping that it will just be a bad power switch that needs to be replaced.  I am waiting on a POST tester I ordered, but wanted to get input from you guys in the mean time.

Make sure the 4 pin connector as well as 20 pin is plugged into the motherboard correctly, coming from the power supply. Then unplug the PSU, remove and reseat the RAM, hold the power button for 20 seconds. Plug it back in, and try turning it on. Let me know if it works!
