ive got a problem thats driving me crazy. after my pc has been on a while (1 1/2 - 2 hrs) it'll hang up. you can still move the cursor around but it shows the hourglass like its processing something. if i leave it like that it will eventually reboot. but in any case, whether it restarts or i restart it, when it reboots my hhd is missing. if i go from that reboot to setup, i cant get my hhd to show up. but, if i restart AGAIN, i can go into setup and find my hhd and save the settings. when it restarts SMART says everything is ok. after a hour or so the cycle continues. it was dong this a few days ago and i formatted and started over but that didnt solve my problem. i thought it might be a virus. its a 45 gig hhd WD white box oem. running on a 1400 athlon t-bird. also every now and then there is a slow clicking that seems to come from the hhd. it slow and in increments of 2 clicks. if i cant find the problem soon it will be in many peices due to a sledge hammer

anyone have any ideas? heres a little system info.
thanx-
