BSoD - want to roll back graphics driver, but can't locate it in Device Manager

Hi - newbies first post on this forum.
Hope someone can help ;-)
I have a Samsung NC10-14G, Windows 7 Ultimate, 2GB Ram.
It has been running find since June 2009 until about a week ago when I started getting the Blue Screen. 
"
Hardware Malfunction.
NMI: Parity check/memory parity error"
 
 
I ran the 
Windows memory diagnostics tool and no problems with the RAM. 
 
 
I've taken the Ram out and put it back - no effect.
 
 
I'm wondering if it could be due to having updated 
my Intel Win7 Graphics Driver a couple of days before the BSOD.
 
 
So now I'm trying to roll back the Graphics Driver to the previous version or uninstall and then reinstall a previous version of the driver...
and this is where I'm stuck...
I can't find the driver in Device Manager to roll it back or uninstall it.
I've
tried googling on how to do this but can't find any info.
Also, is it best to roll back the driver or to uninstall it and reinstall the new driver?
I've downloaded a previous version of the Graphics Driver from the Samsung website Ver 8.14.10.2108, so I'm ready to go....
just need some advice on how to best go about this....
Thanks!
