The system: Coolmaster Silent Pro 1000 Watt Power Supply 1090T AMD Black Edition 6 core Processor Nvidia Geforce 580 Graphics Card Corsair Memory XMS 8GB DDR3-1333 x2 (so 16gb of ram) Western Digital Caviar Black 1TB 7,200 RPM SATA 6.0Gb/s 3.5" Internal HD Asus Crosshair IV Formula Socket AM3 890FX ATX AMD Motherboard Windows 7 Ultimate 64 bit I have ran memtest on it multiple times, used one stick of ram two stick of ram all the combinations possible. I have returned every single part and got new ones. I have tried to change dram voltages, frequencies, timings, everything that I think that would cause BSOD. I'm about to go bald and be girlfriendless if I dont figure this out soon because it's taking up nearly all my free time trying to figure this out for the last two weeks. I dont have to be playing a game or doing anything I get daily BSOD's. Always the same They are all BCcode 109 The other stop error numbers I do not have right this second but I have the minidump files. I don't know to do, please if you can help me I would be so thankful.
