Windows 7: Freezeing sometimes

I have a problem now with freezing... my computer freezes sometimes, and I need to wait at least a 1 minute till it unfreezes. I don't get it. Anyway, I have problems with crashing too. My s**t of win 7 can't ever detect dump files even if it's set to detect it. I don't know what to do! Plus, now when he freezes, I can hear inside my case some small sound just like using a handsaw. After a min that sound is gone then win backs to normal again.




Please help me with this... i think this is related to my HDD, because I had this problem once...but I'm not sure though.... I hope solution will wait me

There are many reasons why a PC " behaves" this way.

Have you experienced a BSOD?

These annoying " gliches" may be caused by an overloaded hard drive, overworked CPU, Malware, running 2 AV 's, unnecessary data, Browser addons or you may have unnecessary programs running in the background etc....

Troubleshooting steps for you to try -

* If overclocking, restore to original.

*Make sure all intake/exhausts vents are clean along with all fans.

*Type event viewer, in search (by start button) > Windows Logs > Application
Look for RED critical errors that say app hang, app crash, or anything that relates to the problem.
Note the event ID, and the source codes.

* Go to search, type device manager and look for any yellow warning markers.

* Run Check Disk.
Disk Check

*Run a scan with either
Malwarebytes or SuperAntiSpyware free.
Download, update & run a full system scan.

*List all the Security software you have ever had installed & currently have now on your computer please.

* Browser addons can create problems.
Check how many you have on your various browsers.
Is each & every one really needed?

* In an administrators account type cmd in search.
In cmd type sfc /scannow.
This will report and fix minor problems.
Take note of what is said at the end.
Should your computer freeze, try to do the tests in safe mode.
