i have a p5LD2 MOBO.
i built my computer back in june 2006 and it has worked perfect until now. sometime while i was sleeping the computer went off. I hit the power button and nothing... so i turned the powersupply off in the back and turned it back on. after resetting thepower supply the computer turns on for about half a second (leds come on, fanspins) then it goes back off. it will not do that again until i turn the power supply off and back on again. the power light on mother board is ON. i figured the power supply went out so i put in a brand new power supply that i happened to have in my closet. it is still doing the same thing,i have check and doublechecked that all connections are are good. the MB is not touching the case and i have tried plugging one of my system fans into the MB CPU fan connecter. that doesnt help either.i would assume that if it was a problem with anything but the MB itself that the power would atleast stay on and beep or let me into the bios.
other harware that i have connected: x1800 video, 2 sata2 drives in raid 0, 2x 1gig ocz memory, MB is asus p5ld2 with a pentium D 3.4GHZ 6 months old. there have been 3 or 4 times duringthe past 6 months that my computer has gone off and i had to reset the power supply b4 i could boot it back up.. any help would be greatly appreciated
********UPDATE 1/11/07 BIG PROBLEMS**********
ok huge problem here.. i bought a brand new motherboard (ga-965g-ds3) cpu( c2d e6600) and case....and im havin the SAME problem as b4....i hit the power button, and the computer gets power for a SPLIT second then NOTHING...doesnt even beep! this board has built in video so i didnt put my old one VC in yet.. only thing the same is power supply, ram, cpu heatsink, and hard drives.
here are the stepsi tookto troubleshoot it.
1)removed hard drives and turned it on, nothing..
2)changed power supply back to the original one from my other computer (i replaced it on my other computer that was doing this from my first post)nothing...
3) removed the ram completely, still no power
4) unplugged cpu fan and plugged in a different fan..notta...
24pin MOBOpower and 4pin cpu power is connected...
not that it matters but i was also using a different keyboard and mouse,but once it came on and went back off again i noticed that the optical mouse was still lit up...
