"""MY NVIDIA display Driver got corrupt every day"""

Problem started few days ago.
i turn on my Laptop, i saw windows loading screen n after that just Black screen i thought maybe logon screen takes time to appear but,
nothing happen i waited almost 20 min's then i restart it, i try again but nothing happen just Black screen again. again restart it! this time i try to go to safe mode it hanged there.
i restart it again, "Using F8" now i go to "Enable VGA mode" finally i can see logon screen n i can able to "log in"
but what i saw my screen resolution has been reduced to 16 bit " 800 x 600 " i try to change the resolution as i apply it again "black screen" n computer hanged. i waited for few minutes... but i have to restart my computer once again.
"i thought maybe display driver got corrupt"
so again go to "Enable VGA mode" Now i uninstall the display driver from Device manager n i restart it. this time i allow window to run normally.
i logged into window and screen resolution was very low.
i reinstall display driver n restart computer, n every thing looks nice, i thought problem is solved but i couldn't imagine that this will become worse!!!

Now every day when i turn on my laptop, same thing happened as i told above,n i have to do same process... "Enable VGA mode" n so on..........
