Guys, my system has following configuration. MB : TA790GX A3+ CPU : AMD Phenom 555 BE PSU : Coolermaster 600 Watt When I try to power on, onboard debug indicators LED1 and LED2 flash for a moment, chasis fan moves a bit and then everything stops. If I remove power from JATXPWR3 and then try to power on, then all lights turn on and cpu+chasis fan start moving but still no video. Please advise what could be the possible cause.
sounds like something is not being powered properly or power issue. have you tried a different power supply? did you plug all the cables in where they are needed shown below? did this system work before and suddenly stop working or are you building it? link to the manual: http://www.biostar.com.tw/app/en/mb/content.php?S_ID=395
