    Hello there, what's the motherboard?

    Make sure everything is plugged in properly - and all the screws that's holding the motherboard down has something between it (I forget what those are called), because if not - it could short out the motherboard.

    LOL Oops, I thought that was your CPU for a sec.

    Just dled the manual and it doesn't say which ram it supports & doesn't support. I'd try another RAM stick because from my experience, SAMSUNG isn't supported by all Mobos.

    Are you getting any beeps from the system when you try and turn it on? Are there any fans spinning? Any LED lights on the motherboard?

    some psu's report wattage is not right
    if the vid card uses extra poewer and has a fan if yuo use any more than 3 fans plus the psu's fan high end system needs more power n oless than 500 watts
    if you have not done so start fresh make sure you reset cmos
    when boards are tested they use diff hardware and this changes cmos
    the don't always reset
    I would start with psu then the video card next the memory
    do you feel any heat from cpu heatsink

    The motherboard your using requires DDR2 memory is that what you are using? if that PSU is one that came with the case then it is probably junk as Sam allready suggested.

    a sata1 hard drive connected to sata2 port will work fine it just runs at the sata 1 speed. I would suggest looking at the label ont he side on your PSU and see what it is delivering on the +12 volt rail if it is not at least 18A then this is probably your problem.

    Looks like iss is offline now, so let me step in.

    Assuming I am reading your post above correctly, you're going to need a new power supply. That one is only putting out 10amps on the 12v rail. If so, that is one cheap PSU. Not enough power for a 6600GT graphics card.

    Even if this isn't the cause of your problems you really need a new psu. That one has no business being in a system with a powerful graphics card.

    Don is right, you need a new PSU. the first P4 system I ever built I had the same problem you are having. checked the PSU and found that the PSU was only putting out 10A on the +12V rail. I replaced the PSU with one that put out 18A and it booted right up.

    There is no doubt that you need a better ps. But dont be fooled by the cheap junky power supplies boasting things like 800 watts and such at a very low price, they twist the facts (lie) about the ps. Go with a brand name but the price doesnt have to be that high either. Go to or, personallly i stay away from (dont trust them and their shipping is too high).
    Here is some further info on ps. The techrepublic url shows a tutorial on how to test your ps lines (rails):

    Here are lists of good and bad power supplies:

    MAYBE but I wouldnt bet on it. your P4 chips sucks up about 9A all by itself so that doesnt leave much for all the other stuff on the 12V rail. even if it does power up your likely to have all kinds of problems glitches and or crashes becasue there is simply not enough power. as far as PSU's go I would go with Antec a True power 430 is not that expensive and should met your needs. and Antec is one of the best PSU's next to PC Power & Cooling PSU's which are very expensive PSU's.

    What you can do is go to, look for power supplies, then, in the search, go for your price range and you will get a list of power supplies.
    Go for Antec, thermaltake, enermax, forton, the ones on the list of good power supplies, avoid all or most of the other names, like powmax and the other names on the list, or names you dont know.
    Here is a list i made for someone else using the $25 to $50 search, but with your video card i would suggest you go at least 400 watts on a good name brand.

    Heres a thermaltake for $25
    The total wattage is not the only thing to look at, by the way. But this unit is 430 watts.
    On this page you will find the thermaltake as noted above, plus another one for $38.99.

    on the same page you find a coolermaster for $33.99

    page 2 gives your a fortron for $36.99 and a sparkle for $29.99

    I did this quickly so you have to check the wattage. But i can tell you that the Enermax i have is 330 watts and i run a p4 2.4, 2 ide h drives, a dvd, dvd burner, about 8 usb external drives and i have had them all up and running at one time, a 32 mb ati vid card, 3 fans, one large fan, on and on.
    So you dont need so much wattage as you do brand name in a power supply, in my opinion. But you still want to be in the 400 watt range with that vid card you have.

    comp12345, for your other pc, we really need to have all the specs on it to make a diagnosis.
    Plus info on the last software or hardware you added, how long ago it was, any system changes you made before the problem came up, or any or changes you made before the problem came up. Was the pc ok and then the problem came up or was it always there, info like that is needed.

    Could be ram going bad but its only a guess, need info as above.
    But you can google and download memtest86 and test your ram with that, but only one stick at a time or it wont work.

    You didnt give the specs.
    Another thing you can do is go into my computer\properties\advanced startup & recovery. There is a setting called "automatically restart". Uncheck that setting and click out and reboot.
    On bootup you may get an error message. Write it down exactly as it is and write it here so we can help you out.
