I am completely stumped. Can anyone help?

I built a computer about a year ago, ordered mostly all parts off of newegg. I’m not sure on my specs, because I cant seem to find everything, and I don’t really feel like looking, but if it’s needed I will. I believe this is a problem with my power supply, but I could be wrong. I have a 750 W Rocketfish power supply. Running Dual SLI XFX 8600GTS video cards. Standard 500GB SATA hard drive, and an IDE DVD drive. 4GB Patriot Extreme RAM.

My problem is when I try to turn on the PC. It powers up, and turns off not too soon after. I can’t get past the windows loading screen, it shuts off before it’s done loading. If I try to turn it on a couple times, it shuts off before I even get to that point, sometimes seconds after I turn it on.

EDIT: When I turn my computer on, I get consecutive long beeps.

  1. Did you use thermal paste?
  2. Did you apply it properly?
  3. Is the CPU fan plugged in and operational?

I actually figured it out. Looks like one my memory sticks, and one of my video cards were both dead.

Two defective parts? That’s pretty unlucky.

TWO video cards, Thats probably your problem.. They are conflicting ..
