Thanks for the interest. I have an asus MB p6t deluxe v2 with new install of win 7 64 bit. Intel i7 950 processor 6 gb ram, Ati Radeon 5770 video card. All updates were installed. I am to the point now that every time I turn on pc I only get desktop image nothing else. But what is happening it seems is that after about 10 or 15 mins it all comes back and stays.
