Hi all, I am having the phenom ii x6 2.8 ghz with 2 gb ddr3 RAM and corsair 620 watt power supplier. I have connected both the 8 pin as well as 24 pin power connectors. There is also proper connection of the keyboard mouse as well as monitor but after that also I am not able to start the system. Whenever I try to boot the system then all the fans spins properly but I cannot see any screen or any sound coming from the motherboard. I have tired many times to boot that but all the times it is showing me the same result. Can ;you tell me that what can be the reason for this issue and how can that be solved. Thank you very much in advance for reading and replying to this thread.
