Yes, it turns out my cooler was broken and the CPU was overheating. Using stock cooler, computer works like a charm!

Is the cooler making good contact with the CPU?

Could be any of several things, but sounds like the CPU is doing a quick thermal shutdown.

Yeah, actually according to the bit-tech review of the 550ti, the power supply i have is fine.

it happened the first time i booted it up, this is a custom machine. Virtual Machine is disabled. It does the same thing whether i remove power completely or not.

evanscott815 : The very first thing you must check prior to connecting any new PSU & GPU setup that is demanding , is the required minimum amperage that the video card requires to run properly - or else the things you have happening will occur for protection purposes. Check the PSU specifications to make certain that at least (1) 12volt rail can provide the necessary amperage (IE: 24amps) or whatever your video card requires in terms of minimum amperage @ all times.

If the PSU meets those requirements , check that all of your main case wiring to the mobo headers are correct (IE : power switch , power led , reset etc.) They are only correct if they are positioned or oriented properly according to the mobo manual or markings on the mobo itself. Then you can check for other possible reasons why the system is not connected properly , or something is shorting out , or a component may not be seated properly etc. as stated above in the other post reply.

Is this you first boot, do you have virtual machine enabled in BIOS, are you removing power completely? This system does have a boot, shut down boot, process when power is removed completely, on first boot, any time, System features are changed and BIOS has to be re written, or if virtual machine is enabled as it boots once for each instance.

The LED readout displays what i think are percentages while starting up, but says nothing out of the ordinary.
Yes, the CPU power supply is plugged in.
The computer is plugged in through a strip, sharing power with my display.
The GPU is powered directly. (What is a Molex?)
8 GB Team Elite Dual Channel RAM (1.65V, 9-9-9-24 timing)
I have an SSD in SATA0, an HDD in SATA1
I have the H100 Corsair watercooler

Thanks for replying so promptly!

Pardons if any of these seems like dumb questions because others folks happen to not do so or include:

What does the LED readout display (two digital glowing numbers) on the board say during this process?
Is the CPU 4-pin or 8-pin power connector plugged in?
Is the PSU plugged into an outlet directly or through a 6-outlet strip?
6-pin for the graphics card connected, either directly or through both molexes?
What is the RAM, how many, their specs (voltage, timings)?
What maindrive connected hard disk or solid state?
What cooler do you have on the CPU? We've had at least one incident before where someone thought because they bought an OEM CPU which didn't include a stock cooler, assumed it wasn't needed, and had similar trouble where the system wouldn't stay on.

Hello There!
I recently put together my first computer:
EVGA 131-GT-E767-TR X58 Mobo
GeForce GTX 550 Ti
Intel I7-960 processor
OCZ Modstream Pro 600W Power Supply

I started it up and got it into BIOS when it suddenly shut off. For some reason the power light remained lit on my CoolerMaster Storm Enforcer case. I have repeatedly tried restarting. Some times it doesn't even reach BIOS, sometimes it will stay on for a while, but it always shuts down with the same results. Please Help!
