I have an MSI 7185 motherboard, a Tagan 480Watt PSU. A "D-Bracket" was supplied with the motherboard which connects to it and has 4 lights, each light combination means different things. When I try to turn the power to the computer on (via the PSU switch) the lights tell me that "The system power is on" and then it'll change to "Processor Initialisation" before turning off.
Another observation I just made, I can't see the pattern behind it or what causes it but sometimes it'll beep, just once (which is what it always used to do when it worked)
The motherboard manual can be downloaded here: http://global.msi.co...amp;type=manual
I tried pulling the mobo/ram/cpu out, so no hard drives, graphics etc and the same thing happens. I removed my CPU and the computer stayed on (again, using PSU switch, not case switch). So I put the CPU back in and tried it without the 4-pin power connector that goes to the motherboard (it powers the CPU) and the same thing happened as if there was no CPU, it stayed on.
Has anybody else experienced something like this before or know what could be causing the problem?
