Hello everyone. I am having a lil issue with my computer. i have a p4 socket 478 psd800x motherboard. It was working fine untill a night ago. Its like in order for me to boot to windows I have to take out all my usb hook ups. Plus i have 5 hard drives,all satas but the main hard drive. I also have the sound card emu1820m witch requires some watts to push the external card. The power supply is pushing 450 watts total. One more thing,with all the usb drives out it will boot,but it will not boot corectly with all hard drives pluged in, it will only boot with only the main hard drive plugged in. Any one can help me with this?
