this particular computer acts as my home theater pc. has 4 drives in it, a 9800pro all in wonder and a hda x-plosion sound card. 300w psu The symptoms: hard drive clicking (turning off, or back on, or both) then either 15-60 seconds later it crashes. locks right up. I used to use the onboard video, but I upgraded to the AIW and it did it before, and still after My prognosis: Its a dying hard drive. the first drive is split, windows/programs drive 10gb and the other half ~170gb. And I think this is the drive that quits. Its a western digital caviar. its used and abused. I had it in 2 different carputer setups as a boot drive and it went through a few winters, still boots ok, and fast. What ive done: ran the windows disk check a few times, came up fine downloaded and ran the WD software, also came up fine. didnt find any bad sectors. checked psu connectors, and tested voltages. at the time, they come up within 5% spec disassembled and reassembled whole computer twice How it happens: completely random, though maybe more so during reading/writing, but honestly its hard to tell. ill just be watching a tv show in mpc, and ill hear the drive click from sitting on my couch. the same click sound it makes when it shuts off. and im like "oh shit did it just click?" then another minute or so into the show it locks up. locks hard, unresponsive to mouse, to power button push, anything. I either hold the power button or flip the switch to turn it off. Im willing to replace the drive and will be soon enough, but ill be doing a fresh install and its not something im looking forward to right now so im putting it off. Is there ANYTHING else I can check before I go buy another drive?
