Hi everyone - I recently completed my first PC build and attempted to clean install W7 Home Premium. My PC spec includes: mobo - Sapphire AM2R3790GX cpu - AMD Phenom II x4 940 3ghz gfx - Sapphire HD4780 1gb GDDR5 ram - Corsair 4gb (2x2gb) DDR2 800ghz hdd - Samsung Spinpoint F1 1TB I am a complete novice so please be gentle! After the POST (I got a single beep - is that OK?) I went into BIOS to set the time/date but did not do anything else (was there something else I should have done?). I planned to partition the hdd during the W7 installation. On booting up the PC with the W7 (32bit version) disc inserted, the installation started. It loaded all its files and then during its next step (I can't remember what that was - is it expanding the files?) I then got the dreaded blue screen of death with the message Page Fault In Nonpaged Area as below: What could cause this and how do I fix it? I then tried to re-boot the PC but very quickly I got a DOS message telling me that BOOTMGR was missing as below: I have since tried to boot the PC with and without the W7 disc inserted but I get the same DOS message. So, at the moment I can't get past this BOOTMGR problem let alone trying to fix the blue screen error! Arghhh! Step-by-step idiots guide to fixing these problems would be most helpful. All help gratefully received - thank you!
