So for about a year my Pcs worked fine, there were problems in between and I had to replace the mobo twice, one DOA, and the other was deffective and died about 3 weeks into PC finally working. Now everytime I try to boot the PC it powers on for about 1 sec before clicking off. A few days back it did that a couple of times (when it shuts off it trys to boot again) and booted fine on the second attempt, but now it just clicks forever. Inittially I thought it was dust build up, the filters were quite clogged with this point and I went to town cleaning of all dust, and it still would continue clicking on and off mid boot. I then thought that the mobo was shorting on the case so I set up an external build same problem over and over. I have no clue what to do now, any suggestions would be great.
