I have a Western Digital 80 gig hard drive /w 8 mb cache, WDC-WD800JB-00FMA0. It makes a "kicking sound" when it boots up, and a few days ago my screen had all of these wierd colors all over it that appeared all of the sudden, so I just restarted and everything worked fine. My temps are all perfect.....any suggestions. I just plan on letting it screw up one day, and have to send it in for warranty and just buy a hitachi drive.
