I have re-installed windows, both the Vista Home Premium x86 that came on it and Win7 Pro x64. I am using Gateway GT5674 with an AMD Phenom quad core CPU. Everything is stock except the GeForce GT 9800 vid card.
The problem is the the file system keeps getting corrupted. It usually takes a few days, but it will start reporting disk errors and starts running chkdsk.
At one point I could not even reformat the C drive using Windows setup. I had a neighbor create a recovery CD that had BartPE on it. I deleted all partitions and the created and formatted the drive. The took a while, about 3 hours on a 500G drive.
But I was able to use the disk again. I reinstalled Windows 7 x64 and it was working perfectly until yesterday when it has all started again.
I suspect the HD controller, but am not sure how to check it. Any clues?
