Security upgrade and video error

[Guest SamT.]

I ran the automatic security upgrades last night and when the computer

restarted, it seems to be running, but all I get is a blank screen that

flashes up "1: Analog Video - Can not display this mode". I tried to reboot,

but the bios doesn't come up any more. What can be the cause of this?

 

Any help is appreciated. I have an intel DG965 MB. Everything was working

flawlessly before the last 10 auto upgrades that MS sent me yesterday.
