Windows 7 64bit, BSoDs, can anyone read the dumps?

Hi folks!
Im at a bit of a loose end and I'm hoping someone on here may be able to help me.
Recently (shortly after updating windows with security updates (see list at bottom of topic), I've been getting BSoD quite commonly just after start-up!
I was wondering if anyone can read the dump files and tell me what's causing them?

I've also noticed that my start-up seems slower than it used to be, although this was even before the windows updates, and all the shortcut icons on the desktop go to a blank white symbol twice whilst the computer finishes starting up, (if the gadget on the desktop is anything to go by, all 4 processors also max out for a short time when this happens?)

Computer specs:
Asus P5Q-VM motherboardIntel Core 2 Quad Q8400 processor
8GB Ram
Nvidia GeForce GT220 graphics card

64bit Windows 7 professional

Updates recently installed from Windows Update:
Hotfix KB979538

Update for Windows KB2158563

Here's a link to the same supply on amazon:

Graphics card manufacturer is Nvidia!

nVidia only produces the reference design for the cards, other companies like eVGA, Asus, PNY, Gigabyte, and others use that design to make their own cards.

Ah ok! Was not aware of this. How do I find out the manufacturer? as this card came in the PC when I bought it! Is this the cuase of my problems?

Run this: http://www.techpowerup.com/downloads/1864/...U-Z_v0.4.6.html and look at the sub vendor square.

Mine reads:
"Undefined (0000)"

Do you have all the applicable drivers installed?

Pardon my ignorance, but how do i tell?

GeForce/ION Driver Release 256 the latest drivers for your video card.

Sorry mate, did'nt get chance to try this last night! At work now, so will try and update the drivers when I get home!
