i just built a computer with a ECS nforce 570 motherboard, a presler 925 3.0ghz pentium d cpu, 1gig kingston ram, evga 7600gt geforce gpu, 160 gb western digi hdd, and a 550w logisys powersupply. after powering on, everything looks like it is going fine. everything powers up, all fans, hdd, dvd, gpu, everything... i can get into bios, but no matter what 15-30 secs give or take after turning it on, it shuts off by its self. can having the case switch wire + and - turned around rma any parts ? i realized it powers on having it plugged in either way, with the same affect.. and im just hoping whatever the problem is wasnt something i did. i hope its just the powersupply.. it seems everytime i try to turn the computer on again, it shuts down after a shorter amount of time, unless i let it sit for awhile.. then ill get a good 30-40 seconds again before it just dies..

Your CPU is overheating. If the heat on the cpu goes beyond a certain temperature, your computer will shut down. Go into BIOS to check your temperatures and watch it rise. Pentiums tend to run hot so you better have a really good heatsink/fan. Also, use thermal cooling compound like Arctic 5.

I assume that you don't have an operating system installed so you can't have a virus.
It is probably an overheating problem. The fact that the longer you let it sit the longer it stays on verifies that. Remove the heat sink, reapply grease and reinstall.
Even without fans operating (which you would see) it would stay on longer than a minute.
Make sure all of your connections are correct and firmly connected.
The only way to check the power supply, is in a known good computer. That is, you have to replace a known good supply with yours.
Since it works the same no matter the wiring of the case switch, that is not the source of your problem.

It might be that the processor fan isn't working and the system is automatically shutting down to protect the processor. It could also be a RAM problem, but typically RAM problems don't even let the system boot all the way.
I had a laptop computer that did this once. I wound up flashing the BIOS and that fixed the problem.
My instinct would be to check the cooling system. Boot into the BIOS and check the cpu temperature. Did you apply thermal paste?

Normally I would suspect an over heating problem,but it doesn't sound like it stays powered up long enough to get hot.With that in mind I would suspect a hardware conflict.What I do is install an old but known good videocard and try powering up,if that doesn't help me,then I reduce the amount of ram,series of elimination

Hi there, I had a ecs a907 desknote computer, and when i wanted to upgrade 128 ram to 256 ram. It had this very problem that you have. And ecs can`t even help me to rectify the problem. And i thought i can download bios and flash it but i just cannot find the bios from ECS website! Will not buy anything from ECS again!

there could be numerous reasons for that... first thing to check really is the power supply, but a 550W one should be ok. what you could do is, try opening up your pc, connecting only the most essential peripherals (monitor, mouse, keyboard, video adapter, HD). if this does the trick, then most definitely, your power supply cannot carry all the load when all your peripherals are connected.
that's just one possible reason...

That sounds like the power supply is overheating. Is the fan spinning?

mine did the same thing after I removed my heatsink on my processor to put on some new heatsink compound. What happened was I had the heatsink on 180 degrees backwards when I reinstalled it so I took it off and put it on correctly and it worked fine.

Overheating or a virus.
