XPS M1730, running unstable (Most of the people SLI)

[GianCarlo]

Hello out there

I am the happy owner of a Dell XPS M1730

Quick Specs:

2.50ghz Intel Core 2 Duo
4GB Dual Channel RAM
2x Nvidia 8800GTX 512MB in SLI
PhysX card
300GB HDD
Full HD screen
Blu-ray drive
Windows Vista Home Premium.

But "feel" there are problems with graphics cards in it. It has started to lag a little bit of COD4 MW, is running with everything at the highest settings, as always, and there has just run as lubricated, absolutely perfect. But after the screen drills (showed strange colors, it gave me so orderly, it was just a screen plug in a cover just had to be printed properly in place again), I think that it is running extremely bad in the game.

Beyond that I had reports on the "error of video hardware" in the windows of reporting and solution center. Well, I updated the drivers for graphic card and it disappeared as the reports so. But still have the feeling that it is not running optimally.

My question is, there may be errors on my graphics card?
and / or is it possible to download any kind of program that checks "the craftwork," and see if everything is OK?

Just right before I called Dell...

BE JUST said to IT'S AN super Computer & IS CORRECT FOR THE HAPPY HOURS!

PS

FOR SLI-people!
In the "Manage 3D settings" in Nvidia Control Panel, there is something called "SLI performance mode" and it stands at "Single GPU"
But you can switch to "Force for the representation of divided picture", "Force alternating billed view1", "Force alternating billed view2" or "Single-GPU" (as it stands on)

MUST be on the "Single GPU"? Think more about 2 GPUs, now that there are 2 graphics cards in rig

Would like to hear from you, thank you for time and help in advance.

Dell Computer has built diagnostics.

Since it is a portable, the PSA (Preboot assessment system) is running out of the BIOS.

It can be started in two ways:
- Turn on the computer the power button while you keep UN button.
- Or, press F12 at the Dell logo and select diagnostics.

In addition, there is something called 32-bit diagnostics.
If you have not deleted partitions situation where it is, would it like to start after PSA else you can launch it by booting on your Drivers and Utillities disk.
Here you could, for example. Custom test run> Video> hardware and memory.

Write all error codes and messages down because it is something that technical support will ask for.

PSA and 32-bit diagnostics, but it found no errors or other things.

Has also been scanned your computer for viruses, there were fortunately no.

Could be I should try to reinstall COD4 MW (but lose all the scores and rank?)

I do want to call Dell tomorrow at a time and fall further if the issue is not resolved.

But one thousand thanks for your help, now I know that for another time that is the thing on a Dell laptop.
