New Build Problems

So I just put a new build together which I purchased on the the 23rd, and I am having some problems. The details of the build are listed below. The problem that I'm running into is I will turn on the psu, and hit the power button on the case and it will turn on and then no more than 10 seconds later shut off. Sometimes after doing this it will turn back on of its on accord and then shut off again instantly another 1-2 times. I have checked all the cables, the ram and its placement, I have tried unplugging the video card, but nothing seems to be working. I have read that this can result from incompatible ram or from overheating of the cpu. Now about the cpu it could be sensing an unusual rise in temp, but there is no way it is on long enough to heat up at all. So any help would be most appreciated. Thanks in advance.

  1. Have you performed every step in this checklist?

    #2 on the checklist is the most common mistake.

    Did you try each stick of RAM by itself in the first RAM slot? If you get it to post with one stick of RAM installed, manually set your ram to DDR2 1066 with 5-5-5-15 timings at 2.1v.

    One major problem is that your power supply is utter garbage. It doesn't have active PFC, only has about 65% efficience (horrible), and has pretty low 12v Amp rating. I don't know if the PSU is the source of your problem, but it certainly isn't going to contribute to a nice stable system.
  2. yeah I looked at the checklist and looks like everything is fine. Also I guess I didnt realize the psu is no good. How would I know that this is the problem and any suggestions on a better one?
  3. You have to do more than "look" at the checklist. It contains tips and suggestions from a number of people and most likely contains the solution to your problem. You didn't answer whether you have tried each stick of RAM by itself in each RAM slot.

    Another quite possible cause of your problem is that the E6300 is a pretty new CPU that isn't supported by any of the stable BIOS revisions of your motherboard. It is supported by the F5c beta BIOS, though.

    You don't happen to have access to an older Core 2 CPU that you could use to update the BIOS, do you?

    The Corsair 400CX is a high quality cheap PSU that would easily power your system.

  4. So actually after trying the same thing repeatedly the computer finally turned on and stayed on. But then after about 4 minutes it said logging off xp and turned off then back on twice and then remained off. So now I'm thinking a problem with the power switch. Any ideas on how to fix this?
