Windows 7 64 bit missing 1.08 gig of ram and i have blue screen of death bsod. Safe modes do not work at all, and none of the other options work either. So between F2, F8, AND F12, nothing works at all to move me forward.. The error says Bad_System_Config_Info, and 00000074 and maybe 4 other sub error codes that are real long. I noticed the ram was down to 2.92 gigs from 4 gigs for a few weeks now. Also, the battery icon has a red X through it and the wireless or network icon shows that it is not working or disconnected. I did try a few changes in Services and Startup before the BSOD. Any help would be appreciated.
