Alright, here's the build: Processor: AMD Athlon 2 x4 640 Memory: 4 GB stock Hard Drive: Seagate Terrabye 7200Rpm Graphics Card: Nvidia Gtx 560 Se Motherboard: Gigabyte 990FX a-ud3 PSU: Corsair CX 500watt And the issue is as follows. Prior to getting the board shown above i had a stock board fro the company that i bought my PC, obviously, as i want to game, i needed some upgrades eventually, so i got the board. but, upon starting it up, windows began to show up, the logo was coming together from the 4 dots.. and right before finishing it would crash and restart. so i was told by a friend that i should re-install windows while using the new board, to set the HD up with the board. i tried to do this with the new board, it would not recognize windows 7 installer on a flash drive or on the install disk, upon putting either into the computer, the computer returns the error: "disk boot failure, insert system disk and press enter" and thus will not work. I used a separate computer to install windows on the hard drive and that worked fine.. but upon putting the freshly-installed win 7 hard drive in the computer, it wont recognize that either.. it says "disk boot error, insert system disk and press enter" So i DO NOT KNOW WHAT TO DO!! please help and anything u give me will be appreciated.
