Hi, I bought Intel DG43RK Board and added it to my PC with processor Dual Cor 2.8 GHZ. It was working fine with all components until recently. Then one day PSU failed. The earlier PSU was 400 w. I borrowed from my friend his 600 w PSU which worked perfectly.Yesterday I bought 650 W PSU and installed. My system does not boot up. When I switch on power Heat sink fan runs and then power trip for 10 secs then Heat Sink Fan starts running but there is not boot up beeps but fan keeps running. Please help me.
