Okay today I gathered my 80 gb hard drive 256 mb ddr ram (will update very soon) 256 ddr ram video card, network card, spare fan, motherboard (KT600-AL) Sempron 2500+ CPU and so on, It seems I have everything I need and when I hooked it all up nothing happened. The little LED light on the motherboard will light up but nothing happens. If I unplug the power supply (it has like 20 pins) on the motherboard and plug it back in my fans will spin for a split second. I'm not too sure what to do, my guess is is that since my power supply has one of those 4 pin connectors (2 top, 2 on bottom 2 yellow wires 2 black wires) that I need to buy a motherboard that actually has a place to put that? I'm really not sure, I thought I knew what I was doing but I guess I was wrong, being a car mechanic i'd think I could figure this out :kaka: any assistance would be greatly appreciated!

    OH and I don't think it matters but I connected the front side power switch and all that in the right places and it does NOTHING no matter what different ways I try to put them in (the correct way and then some hehe) It just seems like I'm having a problem with power supply somewhere, everything I bought is brand new though.

    Couple suggestions....Some motherboards are shipped with the cmos jumper in the clear position. If thats the case, you would not get anything. Also, be sure the board is not grounding out on the case somewhere. The studs you mount the board onto in the case need to be brass or plastic. You could try booting the board outside the case on an antistatic bag like the board came in. if it works outside, then it may be shorting out in the case somewhere.

    the exact same thing happened to me a while back. the computer would turn on for about half a sec, then it would all turn off. the outer part of a fan was touching the case, moved it over a bit, and worked fine.

    The 4 pin power plug is for P4 cpu's.

    Double check to make sure you have all your cables and cards plugged in perfectly, especially your cards. I've done it before and it annoyed the hell out of me. Some cases have an adjustment on the back for the width of where you put in the anchor screw to secure your cards. If your cards aren't sitting in perfectly and are popped out a bit or in on a slight angle it won't work.

    Try running it with only cpu and ram attatched and see what happens.

    try removing all your fans,hd and optical drives to see if the computer starts. You may need a bigger psu or your psu is probably dead. Ok there is also the situation that the mobo is burned( Happend to me. all fans spinning but no boot).

    Alright cool thanks yall, it was actually due to the fact that I screwed the motherboard directly to the case and didn't use any of those seperators to keep from grounding. Well its up and running now :) woohoo. One question I have now is that I bought a AMD Sempron 2600+ and when I boot my computer it says something like 1833+. Am I not getting the full performance of my chip? This computer I'm on also is a 2500+ and it says something like 2200+ during boot, is this what overclocking is all about?

    Same thing happened to me, it was the motherboard, and guess what, it was the Asus P4C800 E-Deluxe like yours (- the "E") airoh69

    You just need to adjust the front side bus setting in the bios to match that of your cpu. Then it should post at the right speed. In effect, you are underclocking your processor. If you increase the fsb to greater than your cpu is rated for, you're overclocking.

    You didn't short something when you screwed it directly to the case and applied the juice!? Luck?

    Right matpoh,but
    You should not be doing this without a motherboard manual with detailed schematics.
    My son and i have many years experience and won't do this yet.
    But please detail "do nothing" Does the Monitor on light come on and do you do this first ?
