monitor turns and off

When installed MS Vista Beta 2 my monitor seems to turn on and off. And keeps doing that. When i boot back in my windows XP nothing seems to be the problem. I also installed the latest Nvidia driver.

Monitor is a IIyama HM903DTA

Mine does that too only the monitor doesn't come back on unless I reboot. I have an ATI All In Wonder and I thought it was the lack of multimedia drivers for it. Now I think maybe not. It too is fine with XP. Never had a problem. I have re-installed Vista 5 or 6 times now and that problem still exists. "Tony" wrote:

The problem may be with the Nvidia driver. With the 5200, I can't even boot, had to go into safe mode, "update" the driver to Standard VGA for now. It's not a good workaround but will live with it for now.
