So there I am, idely browsing my files one quiet night when suddenly the Hard-drive starts making these horrible clicking sounds, like one of the writer arms are stuck or going crazy. Everything locks up and then it crashes the entire system with a win32.sys error. I ponder for a moment and go to reboot, the noice kicks back in. Click-Thunk, over and over again, so I shut it off and give it a minute while I run around panicing (well not really). After a few more boot attepts, the clicking makes a last thunk.. and starts working properly, the computer boots with no problem. Taking this as a sign of impending doom, I back up my files to cd's when, on the third one, a certain image file I've had for awhile completly locks up the system while Nero is buring it. A jpg image. So I reboot and try to bring the image up in IE and.. once again the whole system locks up, because of this one image. In fact, after multiple testing, anything I do to that image, load, virus scan, rename, etc locks the system... except deleting it. Which I did. I figure a spot on the Hd must be to blame and run checkdisk and it picks up a bad cluster on the pagefile and then locks up on test 5. I reboot to no problem but I'm left wondering what the hell is going on? Any ideas or suggestions anyone? To put this story into perspective.. I am running a AMD thunderbird 1ghz 256 megs of ram (I've had 2 sticks on me die between this month and the last) Win2k Pro (all the updates) a WD harddrive (as for what model or type, I don't know) and a Shuttle motherboard with an AMD 750 chip I believe. Any suggestions would be helpful.
