Win7 64 bit random freezes

[Gorbovsky]

Hi

I decided to make post here because I saw you've helped earlier someone with the same problem.

Around two weeks ago I reinstalled my windows. Instalation went smooth, I instaled drivers and all necessary stuff.

After some time my PC just freezed, I was unable to do anything and all I could do was turning it off with power button.
I checked System Logs in Event Viewer but tbh it didn't tell me anything.

Before reinstalation of win7 everything worked for around a year without any problems.

Is there any way to post logs here so someone would be able to diagnose problem ?

My specification:
CPU: Intel Core i5-6600K, 3.5GHz, 6MB, BOX (BX80662I56600K)
GPU: EVGA GeForce GTX 970 SSC ACX 2.0+ 4GB GDDR5 (256 bit) HDMI, DVI, 3x DP (04G-P4-3975-KR)
RAM: Mushkin UDIMM DDR4 8GB(2X4GB), 2400MHz, CL15, Kit, Blackline (997191F)
MOBO: Asus Z170 PRO GAMING, Z170, QuadDDR4-2133, SATA3, HDMI, DVI, DP, USB 3.1, ATX
Power supply: SilentiumPC Supremo M1 Gold 550W, 80Plus Gold, Modular (SPC116)
SSD Crucial BX100 250GB SATA3 (CT250BX100SSD1) (Win7 is instaled on this one)
HDD: Seagate 1TB 3,5" SATAIII, 7200RPM, 64MB cache (ST1000DM003)

Edit: At first I installed fix from this tutorial: Fix a Windows 7 System That Randomly Freezes | PCWorld

but seems like it didn't help for long.

Around two weeks ago I reinstalled my windows.

Why?

There are dozens of potential causes for systems locking up without warning. That is why it can be so difficult to troubleshoot. Power and heat are where I always look first. I always want to ensure I am supplying good, clean and stable power to my computer components because they all rely on it. There is no way normal users can conclusively test a power supply. So I recommend swapping in a known good supply and see if the problem continues. If you still have problems, you know your PSU is good. I also recommend running all computers off a "good" UPS with AVR (automatic voltage regulation) too.

You also need to make sure the interior of the computer is clean of heat trapping dust and that all fans spin freely. Monitor your temps. I use and recommend Core Temp to monitor my CPU temps full time via the System Tray/Notification area. This is nice because you can see your CPU temps under all load scenarios. I also use HwInfo64 to check all temperature and voltage sensors.

You should also probably test your RAM. I recommend MemTest86. Allow the diagnostics to run for several passes or even overnight. You should have no reported errors – not even one. Running with just one stick at a time can also help identify RAM problems. Just make sure you always unplug the computer from the wall and touch bare metal of the case interior before reaching in, and never, as in NEVER EVER touch the electrical contacts of the RAM sticks.

Why?

I changed Win7 version to Proffesional.


Temperatures look alright. I'll test memories with MemTest86. There is another weird thing. When I use chrome and leave it open for some time and for example play game when I come back to chrome later all sites in opened tabs are white and pages refresh. I've never seen something like that. Maybe it's because of deficit of memory ?

8GB of RAM is plenty. If you were running low on memory, you would see low memory errors.

You say your temps look alright, but that does not really tell me anything. What are your temps?

Other users have had issues with Chrome pages turning white. As seen here, disabling hardware acceleration worked for this user.

Your best bet is to start looking through event viewer, rather than guessing at possible causes. Check the Application and System headings in Event Viewer for errors or warnings around the time your PC locks up.
Also. look in your C:\Windows\minidump folder for crash dump files around the time you've had problems. You can analyze them or ask for help diagnosing them in the BSOD forum.
If I was to guess, I'd look at your video card drivers as a cause.

During few hours of working and playing games max temps were aroung 65 celcius degree.
Also I did MemTest and after 2 h 40 mins it showed no errors at all.

There is no minidump. It looks like dump file was not generated as it was not bsod, my pc just freezed and was not responding.

Hi everybody :wave: and welcome to Gorbovsky. :welcome:

Check if piriform speccy or cpuid cpu-z show 1066 MHz (DDR4-2133 - PC4-17000) or 933 Mhz (DDR4-1866 - PC4-14900) as dram frequency.
And if dual channel is enabled: your ram sticks should be seat in the grey slots of your motherboard (or in the black ones as a second choice, only if there are problems with the grey ones).
If dram frequency is bigger or lower than those values, try to change it through your bios settings.
