resetting problem

I have just bought a new system for doing video editing stuff on. The specs are as follows: =

ECS nforce3-a mobo
radeon all-in-wonder 9800 pro
2x512mb of corsair pc3200
200gb SATA maxtor HD
2xSony DVD recorders
500 Watt PSU

I have stuck it all together and there seems to be nothing but trouble with the package. I have issues with everything. Some times it will not boot up at all, instead it will continuously reboot at the XP loading screen. I have also found that on the occasions it does boot up it will hang after a random period.

Also when I try to use the video capture of it it does not work all I get is black screen if svideo and snowy screen if cable input.

Has anyone got any ideas how i go about fixing this or any useful links I can loiok at with regards to the BIOS settings of this board.

 

Take it all the way down to only the essentials(hd,mem((1 at a time )),cpu)add each piece after succesfully testing each part.

What are you using for vid capture(nero etc) I had the fuzzy screen problem with cable when trying capture and found my tuner(hauppauge) to be one channel off(channel 3 from vcr to pc for me )
