hi all, so i put together this pc (or rather my IT friend put it together, i just bought the stuff) and it ran with no problems whatsoever for the first couple of weeks. but the past month has it lag hard or occasionally freeze even with the windows cpu monitor reading 3% usage and the memory monitor reading 25%; and the HDD has over 50% space left. even loading "my computer" is laggy sometimes. i tried using CCleaner, i ran a virus check, i defragmented but nothing is working. pls help! it was working awesome just last month and i have no idea what happened
