Need Help Graphics Dell XPS M1730

Hello all

First time poster here, ive seen many people have gotten some really good help from people here so thought i would post my issue.

I have a Dell xps m1730 with the following specs:
Intel core 2 duo extreme X9000 2,8ghz
Windows 7 Ultimate 32 bit
4gb Ram
2x Nvidia Geforce 8800GTX in sli (512mb each)

Anyway the laptop has been performing fine. Running all the games with no issues. Playing 1080p movies with no difficulty.

The laptop was working perfect with no issues yesterday.

Today i turned it on and attempted to watch lord of the rings extended in 1080p and noticed the video was VERY laggy.

I then loaded up Mafia 2 (which used to run FLAWLESSLY) Now i can barely move in game with so much fps lag.

I uninstalled nvidia drivers, booted in safe mode, ran driver sweeper and removed anything that was left. Re downloaded the nvidia drivers and installed and this has still not fixed the issue.

Im not a pc techie, but im guessing my graphics card hasnt been burnt out, as i have not got a black screen or anything, and the resolution on the desktop is fine.

Can anyone help me out/give me some advice on what to do? Or are the graphics cards need to be replaced?

If they do need to be replaced can i get anything better than the 8800GTX?

Or is there a way i can fix this?

Any help is much appreciated

thanks in advance

 

sorry for double post

as an update

some 720p videos seem to run fine (21 jump street, pirates of caribbean etc)

But games are not running nowhere near as smooth.

1080p videos are big no no (Lots of green colour keep coming up and very laggy)

But as said, 720p runs fine, my resolution and colours are all okay

anyone know what it could be? Or any help on what i could do to try and rectify it?

 

from what I remember from this vintage, sounds like maybe one of the GPU's is the problem.

I believe you can disable one GPU at a time and try testing the FPS speed and see if one of the cards is having a problem.
