Well I don't know when this really happens but this 2 process make the PC stop working and once I look at the HDD light it looks like HDD is working none stop.

When I try to press Ctrl+Alt+Delete the screen takes long time to show up, if even it shows up.

Once I managed to get starting the shut down process it takes forever to shut down, and most time I have to hold the power button to turn off the PC and the odd thing is that if the shut down is really slow and the shut down process is completes then PC will boot up really slow.

How do I know this because I have turned off the boot GUI so I can see the list of the drivers while loading, normal times (when PC didn't friezed/slowed down) or the times when I hold the power button to turn off then on the boot up list of drivers will load very fast as you can't see the lines, but if I let the PC shut down normally (while everything slowed down) once I try to boot up it runs really slow each line takes like really slow then I have to run the PC in repair mode then in the scan won't show any problem but once the scan is done it will boot fast. I don't get any error code or some thing.

Please provide more details. What two processes are you talking about? How do you know that they cause the problem? Is it laptop or desktop? What's your hardware? How often does it happen? What's that wall of text at the end? –  gronostaj Jun 7 '13 at 13:04
    
Run Resource Monitor to see which process trashes the HDD so much: techrepublic.com/blog/datacenter/… –  magicandre1981 Jun 7 '13 at 18:22
    
the two processes are c:\windows\winsxs\amd64_microsoft-windows-explorer_31bf3856ad364e35_6.1.7601.175‌​67_none_afa79dc39081d0ba\explorer.exe c:\windows\system32\svchost.exe i don't know you guys saw the Norton's report but take a look at it my hardware VGN-FG, Core 2 Duo T8100, NVIDIA GeForce 8400M GT 128MB, 4GB RAM and when or why this happens i really don't since there is no logging about it –  idavid Jun 8 '13 at 2:51

It sounds like your HDD is failing. Try downloading Acronis Drive Monitor to monitor the activity and health of your HDD. When the drive has random access errors your HDD will work very hard to access system files and perform system processes.

everything shows ok other than this Current Pending Sector Count,300,197,0,Degradation –  idavid Jun 8 '13 at 2:53
    
it used to happen when i used "End Process" now when i open firefox some times it happens –  idavid Jun 10 '13 at 3:42
    
I'm not sure what those numbers mean. Pending sector count errors are caused by sectors that need to be remapped ([en.wikipedia.org/wiki/… this article)). As far as dealing with this, first you should update the disk firmware. This might stop the errors, but the problem could persist. If this is the case, second would be to clean wipe (use DBAN or diskpart) and see if the errors return. After those two, it might be time to invest in a new drive. –  iamwpj Jun 10 '13 at 4:43
    
what is the raw value on Current Pending Sector Count. what if Current Pending Sector Count wont go higher. can it be the Southbridge due to high or low temp cause pc to freezzz. I did a scan with chkdsk /B then the raw value went higher but normal value went lower from 197 to 195 note that my have 3 partitions. 1.Windows partition (53GB with 4GB free) this is the partition I scanned. 2.Page files (6GB with 200MB free). 3.All other files(404GB with 19GB free). btw this is the model for my HDD WD5000BEVT-00A0RT0. and the WD Data Life Guard say my hdd's health is good. –  idavid Jun 12 '13 at 10:37
