I replaced my PSU because I thought it was responsible for my PC not starting,and now I'm having the same problem.I've dismantled the PC and started from the beginning and its still the same.Can anyone explain this?The PSU is an Aresgame (I know) and comes with a little tester for the main power lead which is the equivalent to the bent paperclip method.The fans on my PC are powered solely from the PSU.When I connect the tester and switch on the PSU, the fans come on,yet when its plugged into the mobo with everything connected nothing happens.I know the PSU is working therefore,but dont get why it wont power the PC.Anyone any ideas or suggestions? First post BTW.Nice to make your acquaintance.
