I need help about my hard drive. Just yesterday, when I used my PC for certain apps and games, they are taking time to load. This happens when I used my PC good for 20 minutes. After that, it gets a little unresponsive and it's frustrating. I blame my HDD because the LED in the case that usually blinks if an app is loading now blinks too often on the said duration. My HDD is a WDC Caviar Black 1TB dual processor SATA.
