I have run sfc scan with no problems found. Included sfcscan log.
As for the drivers,
grdv.sys, I believe is part of easy saver which I have removed and was advised to not reinstall it till the BSOD have been resolved. I have renamed gdrv.sys to gdrv.old temporarily. Could not find an update.
spldr.sys i can't find any update info for it
GEARSspiWDM.sys, i have found an update on gear software site. Can someone confirm that it is the correct one. Driver updates - GEAR Software
amdxata.sys, in the file properties it is showing as 14/7/2009 which is the current version correct?
