I bought the components for a brand new pc just recently, and after assembling the pc everything worked fine. The case is an antec sonata II with the 450w PSU.
Anyway, after a weeks worth of use, the thing has died. Upon shutting down the computer one evening it was left to shut down automatically after the windows updates. The next morning when trying to turn it back on again, nothing. Absolutely nothing at all, the whole thing just isn't powering up.
How would I go about troubleshooting this to establish for sure what the problem is. Is it the psu? the power switch itself? Has the mobo gone?
Suggestions please
