Hello people, I just built a system, I know it's not the greatest, but it's all I could afford right now. Most parts are new. New case, into which I put a new Asus P5N-D MB, 775 socket, P-4 3.4Ghz.with new heat sink, New set crucial 2 sticks of 1GB DDR2 PC2-6400 unbuff ram, 1 new 500GB Seagate SATA HD, 1 used 160GB Seagate SATA HD w/Win XP already on it, 1 used 80GB Samsung SATA, 1 new Bluray burner LG(these 4 units plugged into the 4 SATA sockets in that order, 1 used DVD burner plugged into the IDE as a slave, I had 1 EVGA Geforce 8600 GTS vid card and bought a new one exactly like it & plugged it in as SLI with the jumper connecting the two, the only difference in the two is that the new one has a 4-pin molex power socket which I plugged power to(that's one question, my old one is exactly like it except for that molex connector, if it's needed, why isn't it needed in my old one?) I plugged the one in anyways, but now I have 4 DVI connections, which I plugged the LCD monitor into one on the new card. I also installed a new 750 watt PSU (Silencer) so I have plenty of power. Question, on a new MB like this, do I have to flash the BIOS? Isn't that already in there? The problem, OK I hit the power, I get one short beep, the screen goes to the ASUS splash screen, if I don't hit delete within a few seconds, it will go to the screen where you choose "Start up normally", "Last known good", "Safe Mode", etc, I tried all three, it gets to the windows black splash screen with the meter going left to right, then when windows is supposed to start, it blue screens for a fraction of a second, and reboots. I haven't been able to get past this yet. In the ASUS manual, it says on first bootup to enter setup, and update the BIOS, could this be the problem? I thought it came with a default BIOS already in there? Anyways it gives four different ways to do it, and one of them is through windows, going to the ASUS site, & DLg it there, which gives credence to what I said about a default BIOS already there?? Any help would be much appreciated. Thanks Gus
