Black screen after windows loads. Nvidia driver problem

[Guest Colin]

Hi all...

Was wonder if I could get a little help here.

Yesterday my laptop was completely fine then after playing a game of Dota I left my computer on while i went to make myself some food when I came back the screen was black. I didn't think too much of it so I just pressed and held down the power button to turn it off. I left it off for the rest of the day as I was busy.

Anyway I came to turn it on this morning and noticed that the even at the boot screen it had some artifcating going on. I thought it initially to be jsut a one off thing as the windows logo loading screen came up and displayed no problems. After that however, when the welcome screen should of displayed i get just a black screen. I believe it to still be loading windows normally but just no visual recognition.

I rebooted and went into safe mode which loaded fine. (still artifacting going on in boot screens though).

I uninstalled the drivers and restarted. Got into windows fine now, however yet agian artifcating still going on in boot screen and sometimes in windows.

I tried reinstalling the drivers and rebooting but I get the black screen again.

Any solutions out there for this please?

Colin.

What GPU do you have? I'll bet it's either 8400M or 8600M :)

Sry I should of put my specs.

I have a Dell inspiron 9400 laptop

GPU is a 7900 GS

Running windows XP with SP3.

I also just tried intalling an older nvidia driver... (v 179.13) but to no avail. Same issue. :)

Is it overclocked?

Download GPU-Z utility and post your temperatures.

I found this on the microsoft website. I believe this may be the cause...(I use a HD tv as a second monitor occasionaly - but not at the time that the screen went black). However their "solution" doesn't work as I can't get into those settings as my screen is black!!!

(Two days of reading later...) Umm I meant GPU-Z :) We just need the temperature of your graphic card. Run GPU-Z and go to the "Sensors" tab.

It says this when I open up GPU-Z... "unknown architecture" and it doesn't show any infomation on the sensors tab and the graphics card tab just reads unkown everywhere.
