System fails to boot Tags: Homebuilt Evga Boot Systems Last response: June 5, 2010 4:27 AM in Systems Share BlackKnight7891 June 4, 2010 12:21:56 AM Old system fails to post after installing new memory. EVGA 750i intel Q6600 Corsair RAM TWIN2X4096-6400C5C (2x2GB) DDR2 (Newly installed) 2x1GB corsair ram previously installed. EVGA 8800gt After installing new memory this morning tried to boot the system and nothing appeared on the screen (no signal) post didnt display on screen. Checked the motherboard LCD and it showed error code 91. Removed new Ram and tried to boot, Same post error 91 showed. EVGA motherboard manual simply shows this as "Reserved". Reset BIOS still no joy. found my wireless card hanging out of the pcie x1 slot (must have knocked it out of place when changing the memory over) Pulled that out entirely but hasn't fixed it Cannot see any other lose cables inside the case, (physically checked them all) and yes i checked the monitor cable.
