a few days ago assembled a new build (specs below) upon powering up I got lights fans spinning but no output to monitor no system beeps. I removed everything from the case and breadboarded it, to produce exactly the same result. tried all of the usual trouble shoots pulled everything that didn't need to be in tried alternate ram had no success. so assuming it was either a bad cpu or MB I sent the cpu back ordered a replacement and ordered a basic MB in case that was the problem. both parts arrived today and breadboarded them again with new MB and CPU to receive no post once again. I have tried an alternate known PSU and RAM. not quite sure what else to try? any suggestions would be appreciated.
