Screen resolution is too big won't let me change resoultion & On DxDiag video card information shows N/A?

Ok so i have been recently experiencing problems with my Windows Vista 64 Bit i was failing due to display driver failure so i had to system restore it back to factory settings before the screen went blue when i launched one of the games i play which is Combat Arms and Mine craft it was like a blue tint on the screen and didn't know what was happening so then my computer turned off automatically and i turned it back on 2 minutes later and so then at the loading screen i saw that it was the blue screen of death so then i tried Microsoft start up repair and it failed and including system restore none of it worked after i restored it back to factory settings i was experiecing the same problem with a note window on the down right tool bar saying that "the display driver has stopped working" or Windows has stopped responding" something like that then i checked to see if my drivers were up to date and it said they where but nothing else now my video driver is disabled and the Driver info is N/A.i have pasted the info of the video card from dxdiag logs,

Increase RAM speed to 2/3 , you must be running it on low, also increase VM, click on to maximum power usage and performnce.

Some times using a anti virus also is a source of nuisance.

By the way, don't try to wag a tired horse.

G/luck ;)
