Hey guys, So I just got a new case, and once I had transferred everything over, I was unable to boot up the PC properly. When I first booted up, I smelt something like burning rubber, and immediately pulled the power. Now when I turn it on, it simply shuts down immediately and then repeats about 5 seconds later. When this happens, I can hear what sounds like a click coming from the power supply. So far I have tried taking each individual part out and testing them separately. I even disconnected all the fans, and when I removed all of the RAM and attempted to boot up, there was no beeping noise. I have even used different power supply cables in different power sockets and I ensured every connection was secure. I made sure that the Power SW, Reset SW and HDD LED where all in the correct place, I then did also remove them and attempted a manual start up; same issue. As suggested, I connected a paperclip to the PSU to Motherboard power cable, with one end at black and the other at green. When I then booted up, the fans stayed on until I pulled the power. Thanks, I really appreciate the help I have been given so far.
