Windows 7: Constant Blue Screens from Drivers

Hello

A week ago i decided to update my Graphics Drivers.After intalling and having a go at it for an hour or so,BSOD popped up,saying nvlddmkm.sys is the problem,i've tried seraching forums with no result.I've uninstalled and reinstalled older versions and reinstalled the newest,but with no resluts.The issue at hand has gone so bad,that after the boot screen,the screen stays black and it does NOT continue,after several boots in then somehow manages to boot up.In games the screen's pixels start to mess about,it freeses.Please help

When upgrading your graphic driver you MUST remove all traces of the current driver. In order to do that we recommend using Guru3D - Driver Sweeper

When it is removed then download and install the fresh copy.

Also, I would suggest removing the driver in 'safe mode', rebooting without any nVidia drivers installed for it, so that it uses either the Windows drivers, or no drivers, and seeing if it still bluescreens. The bluescreening could be cause by a coincidental case of hardware failure. This happened with my friends computer. No matter what he did, the graphics card cause the computer to bluescreen. He even tried reinstalling. He ended up getting a new card, and everything worked fine.

Hello again,after several atempts to try and fix this issue,i cannot fix it,i have done everything that you guys have asked me.Not that this would be any help,but i am willing to let someone use TeamViewer if this cannot be fixed

help?
