RE'Side note: my speakers make random beeping/hissing noises every 5 minutes. any idea why?
You're hardrive is either damaged physically damaged.
Or it may be damanged from inside.
:Note 1

efrag you're computer, Remove all the files that you haven't used in the last month. Remove all history of you're firefox. Make sure you have you're sites bookmarked, history files can contain malware,spyware, viruses, etc....
If that doesen't work
:Note 2: The only way to fix that would probably be to either get a new hardrive" If the hardrive is damaged physically" Or reformat you're computer.
Or maybe i am mistaken, and it's just you're fan. If it's your fan,clean it. make sure its not getting stuck, and that's the only possibility's i know. If 1 of those worked for you. Please thank me ? Kinduf new to MPGH "posting wise"
