Problem:
After building this new PC, installing vista (used vista lite software to remove unwanted components) and drivers etc my computer has ran great except for an annoying problem...
The computer seems to load the hardware fine when turning on the PC but when it loads Vista it will freeze while loading (The green lines will stop) evertime. When I restart the computer however Vista will load perfectly fine.
Also sometimes when I restarted it after it froze, the motherboard would send off beeping codes which would either be 3 Beeps then works or Continuous Beeps then I had to manually restart it, and then it doesnt happen again.
I'm convinced it's my harddrive because it used to be in my old XP machine as a second hardrive to store files. The hardrive went crazy and all the files started mixing together yes mixing together (Video Files would start load audio files from games on that hardrive) and some would no longer work.
I formatted that harddrive on this machine, and all works except for that issue.
I'm confused as to what this problem is, any suggestion will be greatly appreciated. ThaNKS
