Ok check it out, here is what i have kingwin mutant x gaming case (i replaced the 420 watt 210 watt max outage factory psu to an antec 430 watt truepower) intel D915gevl mobo P4 530J 3.0ghz cpu 1 gig ddr2-533 pc2-4300 memory for the time being i am using the on board video (128mb) OS-Win XP HD-Maxtor DiamondMax10 80 gig i'm building a computer, i've built a few in the past but i am having trouble with this one. The first time I put it together the power flickered for a split second then the power cut off. I troubleshooted my **** off, everything was connected properly, still nothing. So i thought it was my mobo, i called intel got an rma number and i got my mobo swaped. i recieved it a few days ago, i installed it and it powered up for a min then shut off, if i turned the power switch on the back of the psu off then on it would do the same thing, So as most people would think i thought it would be the psu so today i went out to bestbuy and bought the antec 430 watt truepower psu. so now i have another new mobo the same D915gevl, and i have the new power supply,ok. So I install the power supply and whamo I have power i hear the drive spinning the 3 fans running with the blue leds goin no problem there, but my monitor wont come out of standby, my mouse and keyboard wont turn on, and my cd-rom wont power up, once again everything is connected properly, i even unplugged everything but the cpu/ram/mobo just the bare things needed to be ran, still nothing, i did the whole "take the cmos battery out for a minute and put it back in.i never had a chance to get into the bios or nothing because the computer wont get out of standby, can somebody help?
