Hello! I have a 6 years old HDD, ST3500418AS ATA device, my pc boots (win 7-32 bit) at normal speed, but when I close or open multiple browser/browser tabs/open or close any game/open steam,battle.net etc the HDD light stays on for long(30sec-2min) and my pc kinda non-responsive, I have used CrystalDiskInfo to check my HDD and it shows health status is good, I didnt understand the other parameters there, plz help me on this, what is the matter?
