A month ago I came home from holidays, booted up the computer, got into windows and a few mins later it started to lock up every few seconds. While it froze, I could hear one of my hard drives clicking and spinning up. I have two drives, 36gb Raptor and a 160gb SATA WD. I reboot the computer and got a screen at post saying \WINDOWS\SYSTEM32\CONFIG\SYSTEM is corrupt or missing, run Windows repair. I narrow it down to the Raptor, which has the OS installed, run the repair utility but it fails says something else is corrurpt. Load the OS to the 160gb, run diag on the Raptor, everything is fine. Format the Raptor, load the OS, computers working fine. Three weeks later, same thing happens, drive is clicking after boot, locking up, \..\SYSTEM is corrupt again. I left an OS on the 160gb and thats where I am now, but I don't feel like formatting the raptor to have this happen a third time. The drive is still under warranty (5years ftw) should I just RMA it? Or does this sound like some wierd windows problem caused by a program? I've had the computer for two years now and never had any problems.
