Can't get past welcome screen and other issues

Hi,

I turned on my computer today, it got past the 'starting windows screen' and then the screen was just blank

Anyway, I went into safe mode, un-installed the display adaptor and then re-installed it (the graphics card I have is a NIVIDIA GeForce GT240)

Afterwards, everything seemed fine, as normal, I got to the welcome screen, typed my password, and then it froze

I've tried creating another admin account and it didn't work

I'm running Windows 7 Enterprise edition 64-bit on an Intel i7, 6gb Ram.

For some reason, safe mode works but I can't access my computer normally.

I feel like I have a myriad of problems, thus creating a new thread instead of searching for one which provides 100 different answers.

I think something is up with my graphics card to be honest, in any case, if any of you could help me out, it would be greatly appreciated.

If you think the graphics card is the problem - you can test it here:
Video Card - Stress Test with Furmark

I tried that and it said it "could not initalise ZoomGPU. Furmark start up failed"

I will grab an expert to take a look at this.

Thank you

System restore didn't work either

Bump

Excuse my ignorance, but how do you 'enable low resolution'?

It's okay, I fixed it haha !

You know those metal ports at the back of the computer that are used to cover the graphics card etc

Well one of them were loose and was touching the graphics card.

Anyway, iI thought I better take it out, I did and its working fine! haha

Thanks again for all your help everyone :)
