I recently installed Windows Vista beta x64 bit on one of my desktop. Installation went fine and the system worked fine for a week. Since yesterday whenever i boot my system just after Boot Screen and before Vista logo, it crashes and display a Blue Screen with Physical Memory Dumb error. It keeps rebooting / looping from this stage.
There is no way to get into normal windows mode. I am still able to login in Safe Mode as well as Last Good Known configuration but nothing helps to fix the BSOD. Somebody told me to remove all external devices. I unplugged everything except Mouse and Keyboard but it still crashes and reboots just before Vista Logo.
Any idea what could be the problem and how can i fix it? Many thanks for all your helps in advance.
