    ok, after a long epic battle with a stuttering problem with my 6800/nforce3 combo (which took me about 9 months to find out the problem, check the forums, it's a huge widespread problem), i finally decided to switch my motherboard out for a new chipset. first i ordered an abit kv8 pro, and after i turned on the computer, all the fans worked but nothing was displayed on the monitor. the led indicator on the board told me that it was a successful boot, but for whatever reason nothing loaded. that coupled with a few minor power issues, i determined that the problem was that my power supply was not strong enough for the board (i run 18amps and the 12v rail, whereas the abit forums suggest 20a for that specific model). so i sent the board back and ordered a gigabyte k8u with a uli chipset. i put it all in, but the same thing happens (minus the power issues). fans spin, i hear the hard drive start up, but nothing happens. i know that there can be issues with booting windows when changing chipsets, but this doesn't seem to be the issue at hand. this is my first time dealing with mobo changes, so i could very well be missing something simple. if anyone knows, please reply.

    ps i'm certain everything is plugged in correctly

    MS: I assume you loaded the drivers for the chipset and video card?

    You can't load the drivers unless the PC will reach POST (Power On Self Test) and the BIOS loads, which by the explanations given is just not happening.

    I would still suspect that you have a Power Supply iisue, as unless the power supply gives a "Power_OK" signal to the motherboard, the CPU will not reset and allow a boot. Even though the fans etc may work.
