When i press my power button the cpu and rear fan go on for a split second then it shuts down? I was going to clean my pc and i saw a good spot to put some cables so i took out the power cable out of the mobo (the 2pin one) and moved it and put it back. After that the computer wont start. It started after 6/7 tries and i thought it fixed itself so i turned it off and when i tried turning it on again same problem D: Please help (oh and the parts are almost brand new and i had touched the case many times so i didn't zap it)
