Hi all could anyone help me with this problem? My system is a self build with Asus P8Z68-V Pro and Intel i5 2500k chip. I installed 6 updates from Microsoft about 7:30 this eveving and my machine has not worked since. It will not boot from hard disc or Win7 CD. Screen is white all the time. I have disconnected HD and I cannot get into the BIOS either. Any thoughts?
