Help with error with a hp pavillion Dv6000 Vista laptop

Help with error with a hp pavillion dv6000
when i start my computer up then type my password in to get into my admin account, i get these errors-
Error loading C:\Windows\system32\NvMcTray.dll
Error loading C:\Windows\system\32\nvsvc.dll
Error loading C:\Windows\system32\NvCpl.dll
and i get this message,
Windows Explorer has stopped working...
Windows Explorer is Restarting.

It keeps restarting over and over again, i can't do anything...if i start something up windows explorer restarts over and over again, cant do anything about it as far as i know, if i can find my recovery disk, i think that would fix it, but is there anything else i can do right now?? i appreciate your help...thanx

aint they all dlls which are part of the nVidia forceware drivers. i you have an nvidia graphics card i suggest reinstalling the drivers should be on your utilities disc , if you have one, or you will have to down load it from hp for your laptop not from nvidia, due to a long winded OEM requirement that i cant be arsed to explain. have to start in safe mode with networking f8 at the windows boot logo, just after the bios finishes loading.
