Hi all! Please forgive my "newb-ness", but I'm in the process of building my first rig and I've run into a snag. First, my specs: ============================== CPU: Intel Core i5-3570K @ 3.40 GHz GPU: EVGA GeForce GTX 560 Ti Mobo: Gigabyte Intel Z77 (GA-Z77X-UD5H) RAM: Corsair Vengeance 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) HDD: Western Digital Caviar Green 2 TB PSU: Corsair Enthusiast Series TX850 Optial: Sony Optiarc 24X DVD Burner Case: Antec Nine Hundred Black Steel Montior: ASUS ML228H OS: Windows 7 Professional (64 bit) ============================== Now, in first putting it together, I had no problems installing Windows 7. After installing all drivers and updates and in the spirit of being thorough, I used Gigabyte's @BIOS utility to flash to the newest bios version (F7) from the factory default (F4). Bad idea! Almost immediately, the OS went wonky. This is probably where my inexperience really hit hard. I thought maybe OS files corrupted somehow, so I just needed to reinstall the OS. No luck. Currently, I can't even install Windows 7 on the hard disk. I can get to "Unpacking Windows files..." when the installation freezes and (eventually) the system reboots on its own. I'm at the end of my obviously feeble skills, and I humbly ask: "what the heck did I do?!!?" Thank you all, in advance!
