Ok, I'm new to these forums so I hope I'm posting this in the right spot since it has to do with either my mobo, my HDD, or my CPU (Near as I can figure). About 2 weeks ago I got a new Athlon X2 4400+ and a new WD Sata HDD off of Newegg. I should mention that I bought the Sata drive to replace an older 60gig IDE HD that would make alot of clicking when I'd start up games like UT 2004 or WoW, but never when I booted windows. I took out my old 60gig IDE HD and replaced it with the Sata, had some trouble finding the right drivers for XP to load onto it, but once I did there wasn't an issue. I let the HD run for a little under a week without any noticeable incident. I then popped out my old Athlon 64 3500+ CPU and put the new X2 in. There weren't any problems for a couple of days, but now I get frequent reports of bad (but repairable) sectors on the HD from the WD diagnostic, and when I boot windows it sometimes (mostly after being off all night) clicks once and ruins the bootup, causing the PC to reboot itself.It usually takes 3-4 tried to get it to boot right. On top of that it clicks and freezes UT 2004 like the old one did, just not as often (maybe 5 times out of 10). I should mention that I installed all the drivers for the CPU and the HD off of their respective websites and I still get these problems. Any help would be greatly appreciated, since I'm getting close to the date I can RMA the HD, if that is what is causing me all these problems.
