Bought a new computer and a C IV F Motherboard and 2 packs w 4 GB 1333MHz Ram (Corsair) : "TW3X4G1333C9DHX", it's also listed in the vendor list. Still, 1 and 2 test boot was successful showing 8GB RAM in BIOS. But once i had installed Win7 P, i got a bluescreen. When trying to start it again, nothing happens. (black screen, nothing happening). Realizing that it might be the RAM i tried to switch place on 2 RAM bricks, the one at slot B1 i moved to A1 and A1 (probably a defect one now) to B1 and got a message the BIOS was corrupted, and he started to search for USB, CD -drives with another version of BIOS to "flash" with. If i change them back nothing happens at all. But, if i remove the RAM brick at B1 it starts booting without problem... :s Any one who know what it might be caused by?
