Hiya guys. I've had this annoying problem for about 2-4 months on it ever since i installed windows 2000 server on my machine. Basically if I say use my pc for 15 minutes the hard drive will just suddenly power down and will take a short while to powerup again. I thought it was power management but it's all been disabled in the bios and in Windows 2000 Server. I don't think it's bad sectors or a duff drive because it used to be fine a while ago. And I don't think it's any power issue (though I haven't tried this with a higher PSU) but I have removed an old 4 gig hard drive and lower my GFX overlcoking to not so high. I've only Y splitted the power once and that goes to a speed controlled cable from maplin. I have hooked up one fan at 3 volts and one LED fan at 5 volts. So I don't think that should cause to mutch of an issue. I cleaned out about 2 gig today and defragmented the hard drive but that hasn't helped. I just don't wat this problem could be. I keep thinking I might of missed something in windows 2000 server because I'm new to this (though I have vast experience in XP, 98 etc). I hope I've given enough information it's just an annoying problem because it goes down to 1fps in Elite Force (1) when I'm playing online gaming. I can't live with it now please help me out. It just kinda powers down for a short while thats all i can say. The drive is a ST330621A and it registered 27.9GB under windows and I'm using the NTFS file system.
