Computer freezes, how to identify the cause?

Question

Hard disks

Periodically, all applications freeze for 10 - 20 seconds. WIN7 x64 installed a month ago. Almost pure Windows. I think overheating of the screw can? Here is a photo, the first disk is the system

ps did a test of RAM using Windows, no problems were identified

Answer 1

1. It is still more reliable to test the RAM by external means (take an empty flash drive, a utility for creating boot disks and the good old memtest86, something like this: www.pendrivelinux.com/testing-your-system-for-usb-.. . ).
2. Next, look at the Windows system logs (type eventvwr in the command line) for errors related to the disk. Next, we check the status of the disks with any program that shows SMART attributes (error counters, etc., for example, www.netpower.fr/smartmontools ).
3. Next, we are looking for the so-called. rescue disk from any antivirus vendor (they are free, e.g. one , two , three), download, fill with acc. utilities to an empty flash drive, reboot from it and scan the system.
Then you can already objectively drive hardware stability tests, chop off / uninstall different software one at a time, or stupidly rearrange the system.

Answer 2

Sometimes, after hanging, I reboot the computer, such a message appeared.
In general, yesterday I shook all the wires, and think it seems like there were no freezes yet !! It remains to test the computer for a couple of days, if the problem does not manifest itself, then excellent)
