I am trying to upgrade my system new mother board, video card, and processor. They are, MB = nForce4-A939 CPU = AMD Athlon 64 3200 VC = ATI x700 Pro PCI Express HD = 80 GB western digital RAM = 2x 512 DDR (1 GB) OS = Win XP PRO sp/2 W/ Large HD support 430 watt power supply w/ PCIe enabled (24 pin) After switching everything out from my old AGP board I can not get the system to boot up. There are 2 posabilities I found reading through the ATI manual. ONE, when I try to boot up I get a beeping which (by the manual) indicates that the power supply to the video card is not connected correctly. However I have 2 power conections to the MB, the 24 pin main connection + a 4 pin 12v auxiliary power connection. ( There is NO direct power connection to the video card possible). Secondly, it said to "Update Your AGP Motherboard/Chipset Drivers". But if this is a brand new board that should not be a problem, right? None the less I'll try it, however I have 1 PCIe board so I will have to break down my system and do this using my old AGP board? Just to make it clear the MB is a PCIe board. If anyone has any ideas to what my problem may be please HELP!!! Thank you, Dana PS - I've been drinking so if anything sound odd please feel free to comment and I'll respond ASAP.
