Hello friends, I am going absolutely crazy. I buy parts and build my own comps. Always have. Everything went smooth until I looked into Cmos and saw it would not allow me to change the boot configuration. I then noticed no lights or doors worked on my DVD/CD's, making it impossible to load Win 7. I have tried 3 different ribbons, CS, MASTER, SLAVE, nothing works. I unplug the ribbion and left the power to them and the lights come on, they want to work but I can not use them without the ribbon plugged in. This is Windows 7, 64 bit My system I am building, Cool Master CM 690 Case Intel Core i5-750 2.66Ghz 8M LGA1156 CPU ASUS P7P55D Pro Intel P55 Socket LGA1156 Corsair 4GB DDR3 PC12800 1600MHz (2x2GB) Class 9 WD VelociRaptor 300GB SATA HD 10K/16MB/SATA-3 ULTRA X4 1050W POWER SUPPLY MODULAR EVGA GeForce GTX 260 Core 216 Superclocked 896MB X2 but only one installed atm Asus Quiet Track and Compact Disk I'm been trying to install Win 7 in with no luck. Please help!
