Recently purchased a new custom computer, actually 2 of them, for my brother. Current specs are Gigabyte P55-USB3 MBoard, Intel i5-750 Processor, geforce gtx 460, and 650 PSU, if needed i can get the make of that as well. We tried to do a clean install of windows XP on his 1TB Western Digital HD but everytime we install, it will reboot to continue the process but then when it's "Loading Operating System" it just restarts the computer and repeats. Not once have we came to windows, never has it finished loading. Please help someone, I've tried a bunch and read a lot. Thank you. 8GB of ram as well
