why does my computer keep freezing every few seconds

I have been have a very annoying problem for the past few months: my computer has "fits" where it freezes periodically every couple seconds. While it freezes, I can still move my mouse around, but applications go non-responsive. This is what my CPU usage looks like:
The laptop is a Thinkpad E530, it has a Core i5, 4GB of RAM, pretty standard. I am running Windows 7 x64. I have tried reformatting but the problem persists. I haven't found any offending programs using the Process Monitor, etc. and my CPU doesn't appear to be overheating (it stays at about 70C). Because its a laptop, I can't easily change parts out to see if its hardware related. I used a hard disk diagnostic utility and it appeared to be OK, as did my memory using MemTest. Is there something I'm missing? Is this computer just a lemon? I'm 100% out of ideas, please let me know if you can help. Thank you for the response guys. Well, After I performed the clean window install.

I haven't updated the windows nor installed any additional drivers. Hanging issued was developed a week earlier and I have performed windows installation twice since then to get rid of the problem as I mentioned in the earlier post. Here are the answer of question you asked. 1) Microsoft Windows Version 1607 (OS 14393. 0)Windows 10 HomeHere are the test results:Microsoft Windows [Version 10. 0. 14393](c) 2016 Microsoft Corporation.

C:WINDOWSsystem32 =========================================================================== =========== Well,I haven't notice any difference in the boot time or shutdown time after the evaluation. The freezing problem is still the same, I have also noticed one more thing that when freezing happens while watching the video not only video freezes but also make a buzzing sound until the laptop comes back from the freezing mode. I have read somewhere that frequent freezing problem is due to hard disk or hard disk is dying something like that. I have also attached the bsod log collector results. I am very New to this form so don't know much about it. Again, appreciate your help and looking forward to your reply. Best,
