I'm kinda suspecting the HDD as the cause since whenever something randomly goes "not responding" and then try to call for Task Manager, it doesn't come out until it responds again. Another thing is that when I tried to boot into safe mode, the problem still occurs and not to mention that no errors are shown in the Event Viewer
What I really want to know is if there is something I can do to fix the problem without reformatting or buying a new one (and use it as the system)?
And also, if I do need to resort to buying a new one, then would it be possible to keep the hard drive without causing those unresponsiveness to occur? (Well, not on the system anyway... if it occurs only to that drive, then I guess it's bearable?)
