Posted on 2004-08-25
Hello, first there is the system : Mainboard: Epox 8KDA3+ socket 754, 512 MB Corsair XMS , CPU Athlon 64 3400+ for socket 754, Graphics Card is Saphire Radeon 9800 pro.....
All of the components are NEW !! I Installed the whole System....Plugged in the CPU and the Mainboard in the Case....All Cables are plugged in right !! I proved it 10 times ! All LED´s and IDE Cables and the 2 Powersupply Cables onto the mainboard are plugged in. CPU Fan cable is plugged in and the power supply for the Graphicscard. I also reseated RAM and CPU and all is right i think ! My Case has a Frontpanel Display from which the Cables like HDD LED and PWR Switch are coming.... When i push the Power Button all begins tu run...all FANS are running and the Mainboard shows FF on the Code Display on it. This remains 1 Second and then everything turns off instantly....I searchd if i had plugged a cable wrong with plus and minus but everything is OK !!!! What can i do ?? What could be wrong ????
