Intel is the manufacturer of the GPU tech ONLY they did not make the mobo. So (correct me if I'm wrong patio) what patio is saying is go to the mobo's MANUFACTURER'S site and DLoad ALL the 64-bit drivers for your mobo.
I agree with that.
Another thing to consider is that if you monitor says no signal for less than a second or two then you could have a monitor issue. It'd be a good idea to try another monitor to see if there is an issue with your monitor.
