FSX crashing - Nvidia card?

[Lincolnshire Poacher 7]

Whoops, already posted this in FSX forum and just seen the sticky so reposting here.After my hard drive and motherboard failed I have just upgraded my computer, I am now experiencing crashes, when windows restarts it tells me it was an Nvidia graphics problem. What happens is I am flying ok then the screen freezes, most times the computer restarts on its own, occasionally I have to turn it off. I have downloaded what looks to be a newer graphics driver but when I go to update it through device manager it says I already have the most upto date version installed!! Any help would be greatly appreciated. My system is as follows Inno3d Nvidia Geoforce9800GT (driver version 7.15.11.8206) ECS Elitegoup GF8100VM-M3 motherboard AMD Athlon 64 x 2 5600+ 2.8GHZ 4gb ram 600gb hard drive Windows Home Premium 32 bit Microsoft FSX (Acceleration) VFR Real Scenery for FSX volumes 1 and 4

What is the DLL's name?I had similiar symptoms. In my case it was not a GPU but RAM. I have to downclock it from 1333 to 1033, I do not know why, but FSX does not like a fast rigs
