Well recently my 10 gig hard drive which i have had for about 2 years began acting funny, It will make a "clicking" noise, and It will completely freeze in windows. So I took out that hard drive, afraid that it will die completely. So I installed a new hard drive which is the same brand as the big one (Western Digital) And I installed the same windows and everything as the other hard drive. And the other day it did the same thing, began clicking and running VERY VERY slow in windows, so I reset my PC and when i did windows didnt load, I got an error saying it couldnt initialize VKD, An error with the registry, and a stack overflow....
