Monitors freeze then turn off but system stays on

[Eavesdropper]

This has been happening for a LONG time. I have two monitors and while im playing games it just freezes up and the monitors turn off only leaving the system still on. I've just replaced the PSU to see if it was a bad PSU, checked ram, formatted, added thermal paste to CPU fan, and tested my GPU.
The only thing i haven't tried yet is replacing my motherboard.

Have any ideas?

Does it happen when only one monitor is plugged in? Try both monitors individually and see if they still freeze.

I've tried it for a bit and played the game, its random but this time it did not freeze. Could be a coincidence. But what could cause it to freeze with two monitors?

The power is just most likely not circulating properly. I'm about to head off for the night but I'll make sure to look in to it for you in the morning.

Ahhh alright thanks.

So i've done some research, and I think the main issue is derived from the power supply.

Download any program that allows you to clock your graphic card (I use nVidiaInspector) and underclock it a little.

I often had crashes in, BF3, Diablo 3, Spec ops the line, and similar games on my old PC. But since I turned both GPU and graphic memory 40 MHz lower, I never had even one crash, and the underclocking had no serious impact on fps. Seems like capacitors cant handle highest performance any more.

Let me know if that solves it.

I have underclocked my GPU and graphics memory 40MHz. The problem still persists, just to make sure its the dual monitors, I will use one monitor for a longer period of time to see if it would crash or not.

Edit: It still crashed even with one monitor, but i realized the SLI selector was on the dual video card so i flipped it around. Could this be whats wrong?

It most likely was, If your rig is trying to pump out power to two cards and there's only one plugged in it could've caused that.

Hmm even after that, its still happening. If this helps any, my specs are:

Intel Core 2 Duo E6550
ASUS P5N-E SLI Motherboard
GeForce GTX 550 Ti 1GB
APEVIA ATX-CW500WP4 500W ATX Power Supply

run DDU (display driver uninstaller) in safe mode...I would also reseat all wires from your PSU, Reseat all ram, add-in cards as heat can cause them to slowly slip out...or while installing the new card you could have accidentally screwed up the connection between wires/components and the motherboard.

The problem has been fixed. I guess the problem was the driver, i usually use DDU but never use it in safe mode and dont restart. Thanks a lot.
