I am running Vista Ultimate, have 8 gigs RAM, 600w PSU, AMD2 64 x2, 3 cards installed. A Nvidia 7600 SLI graphics card, a USB card and an Ethernet card. I also have a DVD burner, 2 internal HDD's and a card reader installed in bays. I originally had an ASUS M2N4-SLI motherboard and for almost a year now I've had various power issues. Some cards not showing up or my card reader not showing... I've replaced 3 PSU's in the last year that seem fine at first then the same thing starts again. A few days ago the machine died completely. At first the machine wouldn't start at all. I was at work and had my daughter turn it on while I listened over the phone. I heard 3 beeps, but now that I think about it, I think it could have been the battery. She wasn't sure where they were coming from. I had her try again and actually heard Windows start up music but there was nothing on the screen. I connected remotely and my remote screen showed black even though I could connect. When I got home, I turned the power on and got nothing but a quick flash of case lights and the fans moved slightly. I noticed that everytime I turned the power switch to the PSU on, my battery would go into overload for about 10-15 sec and then back to normal. When I switched on the computer I get the same slight power and then nothing. I think the surge protection on the PSU is kicking in. Last night I installed a new motherboard hoping that was my problem, but I am still getting the same results. I have unplugged it from the battery and directly into the wall and plugged it into the wall in a totally different circuit in the house. I get the same. Something I think is shorting in the case. A card or possibly the case itself. I noticed a few of the molex for case lights, fans... are wore to the point that the pins shove out the back when I plug in the power. I am sorry to make this so long, but I am completely confused right now and I wanted to be as detailed as possible. Something is overloading. I don't think it's RAM. I took out the new RAM and replaced it with the original and I get the same results. I appreciate anyones insights or suggestions. Tonight I start unplugging to determine (hopefully) the problem. I know I should have before hand, but I had planned to change MB anyway eventually. Thank you all for any help you can give.
