Windows 7, 64 bit, 8 Mb ram & 500 Gb HD. Computer will not load. Eventually it will partially load to BSOD. I have tried everything that I know to do to try & break this rhythm and load to safe mode. I have tried repair, load safe mode with command prompt & all the other safe mode options. I have recovery discs that will not boot up system when boot sequence is CD first. You may say that I have run out of options and am scuppered. I need some help, please.
