Windows 7: Black screen, safe mode, no networking

I am experiencing the black screen issues with my new windows 7 lenovo laptop. when it starts normally, I can get to my user logon screen but when I select a profile the computer takes a moment to load through the welcome... part and then just a faint light blue screen with cursor. In normal mode I have a cursor but no button or keyboard functionality whatsoever. I can boot the computer into safe mode with full safe mode functionality.
I have spent literally 3 days working on the issue. I have tried everything I can to this point. Re-installing my graphics driver, disabling it all together and trying a new boot, same result. I've deleted all user accounts and created new ones (as I said this laptop was brand new so I don't have a lot of personal data on it, none anymore) as well as checked my winlogon/ shell to verify explorer.exe. System restore and Boot repair are also not working to help the issue at all. Please I need help, my girlfriend needs to use the laptop for school so I have to get it running quickly and cheaply.

Hi gagnrad ,Welcome to the forums, As the laptop is brand new so still under warranty I personnally would return it to the retailer and let them sort it out for you

I support what my friend Pebbly has said....

You say your computer is new...and I would imagine under warranty.

A new computer should not be presenting with the problems you have listed - & we volunteers should not be putting at risk the rights,YOU, the consumer has under that warranty...

Be aware that attempting any subsequent hardware troubleshooting steps may, in some cases, void your warranty.

I strongly suggest that you should seek further advice asap.

Under Warranty terms a duty of care applies.

Let us know what eventuates please.

I suppose I am just too stubborn to use the warranty help. Got a hold of an identical laptop for a couple hours and just made a new set of system image discs. All is well, thanks for the help folks.

Thanks for keeping us informed.
Nice to note all is now well.
Safe surfing.
