hello,
my dell inspiron desktop 660 is freezing up -
am only using 9% of hard drive-
if I leave my pc on for an hour or a day- it usually starts making this noise every 2 seconds- hard to describe - but a hard drive sound- da da da da - usually try to get online after touch mouse or keyboard to awaken pc- and then it freezes or moves real slow-
tried malware bytes, super anti-spyware- running check disk on boot up- disk defrag-
usually one boot up solve problem and noise goes away and can use computer - sometime have to reboot 2x

can it be my hard drive? or os?
it's happening now all the time
thank you

The noise could be a bad hard drive or clogged CPU cooling fan or case cooling fan causing overheating and thus the slow or frozen state.

Check and clean air vents of debris.
If you have the skill then open the case to clear debris.
Otherwise, with the PC shutdown, a vacuum cleaner is great for sucking dust from air vents, etc.

Download the UBCD and run all hardware diagnostics to rule out possible hardware failure.

The following website gives you an idea what the various different types of hard drive failures sound like, If the noise sounds like one of these sounds then you probably have a failing drive. If it is fan sound, you can run the dell diagnositics both on the fans and the hard drive. To boot to the diagnostics, when you first start up the latop start tapping f12, then you will use the arrow key to scroll to the diagnostics. If the sounds do not occur when running the diagnostics or the tests run fine, then the sounds maybe coming from your speakers.

can you record and post the hard drive sound? that often helps
also - are you sure it is the HDD?

look also in event viewer for errors - or warnings

test if it happens with a clean boot also :
run msconfig - select startup tab, click disable all
reboot and test

FYI
The guide for using the Dell Diagnostics can be found at this link:
http://www.cs.utexas.edu/~deke/laptopsupport/manuals/d600/diag.htm

Also could be from the PCU fan debris causing overheating and excessive fan speed to try and compensate...
A overheated PCU can aslo be the the weak link...

I prefer UBCD diagnostic tests to get to the root cause of your problem
