Computer crashing...Asus EZ Plug...

My computer has been crashing (made a thread about this earlier). It's almost as if the power plug has been pulled. I recently upgraded from a 7950 GX2 to SLI 8800 GT's. Now I have had the power going to the EZ Plug, ever since my previous setup. I read somewhere in the manual that if you have a 20 pin atx setup (I dont)and or when the video card doesn't have a slot for power to be directly plugged in (It does have a slot), you need to have the EZ plug plugged in. I have power goingintoboth cards and the EZ plug. Could this be the reason behind the crashing.Before you ask its not overheating, I have determined that.

Thanks, in advance.

If it's not overheating then there aren't very many other reasons for it to power off. 1) You did a clean install of the video drivers, correct? 2) Make sure you have the Windows BSOD enabled (Start -> Control Panel -> System ->"Advanced" tab -> "Startup and Recovery" settings button -> uncheck automatically restart). If you get a BSOD make note of the error number and message. Also check error logs (Start -> Control Panel -> Administrative Tools -> Event Viewer). 3) Another reason for the power off could be because of lack of power. When does it crash--during intense gaming, or while sitting on your desktop?PVCSnathan

Thank You for your help,

A few things to note:

1) I have uninstalled and reinstalled drivers many times. I have also tried different drivers.

2) I'm thinking its power related. First of all I upgraded to an sli setup recently. Installed two 8800 gt's. I have had it so the power connected to the cards comes off of other things first. In other words it doesn't come directly from the power supply, but through many 4 pin connecters connected together and finaly to a 6 pin adapter and to the video card. I recently found two 6 pin connecters stowed away deep in my case ironicaly marked PCIE-1 and PCIE-2(they come directly from the power supply). I connected those to the cards rather then the previous setup. I am wondering whether this will fix it?

3) Could it be a faulty card? Keep in mind the time in which it shutsdown varies, usually takes a while (almost as if overheating)

4) Finaly chance its a faulty powersupply, or failing power supply. I have only had it for about a year and a half too two years.

Thanks again, any help is appreciated.

and yes it crashes in intense gaming
