Windows 7 Random freezing Please help

[Alexandar Radovanovic]

Hello everyone

Im asking for your help because google cannot help me and I don't know what to do.

So what happens is when ever I do something on my PC it randomly crashes/freezes with strange buzzing sound comming out from standard audio output. Freezing happends mostly on games and I have tried many tests, memtest, tests for psu, for graphic card and CPU. It was all ok

So freezing happens after some time of doing things, and as mentioned it happens even with surfing on internet or doing some other stuff like editing videos/pictures etc.. Tho it happens most on games like league of legends, like far cry 4 and stuff.

HDD remains mystery because I cannot/don't know how to check it.

Temperatures are fine
CPU - reaches most 50
Graphic card - reaches most 70

So my specifications are;
CPU: Phenom II x4 960T
Graphic card: AMD Radeon HD 6970
Motherboard is MSI something I will tell you if you need it
RAM: 8 GB
PSU: 550 V
HDD: ST31000528AS ATA Device (but it is actually connected with SATA, idk what it is, maybe PC cannot recognise HDD??)

If need something more tell me.
Please Help

For testing purposes I would suggest taking the side off the case and using a floor fan temporarily to help dissipate the heat and enhance airflow.
If that resolves the problem, then you know what you have to do, which may include purchasing another case to better facilitate cooling and the addition of more fans.
Be careful when adding fans and the direction of the airflow, everything blowing in does not help anything. You must exhaust the warm conditions inside the case, and if the PSU fan is the only fan exhausting, then it may not be up to the challenge.

Well, for the CPU you can't really put another fan in. The important part is to have the fan clean from dust, as well as the metallic part = heatsink, which is in contact with CPU itself, between the fan and CPU take a search with "heatsink". In order to do that, you need to remove the fan, and preferably the heatsink too - when loosing the heatsink you should clean it, also from old heatpaste = paste that gives a true contact with the CPU, since they aren't 100% suits. Replace it with new heatpaste. NOW this may all be slightly problematic, thus I recommend DON'T do it, if uncertain. And I do believe your problem is Mobo temperature = result of common case warmth.

But still, you should clean your CPU cooling now and then, depending on circumstances, at least every six months - if you live in a desert area, you have more dust, and vice versa. In Africa, where the comp temperature is 40 degrees Celsius at start, since air is 40, problems are quite different from Greenland, where start temperature may be -40 degrees Celsius. In comes condensation, elephants and ice bears... whatever?

With the general case part, fresh air in from bottom, rather through a filter to get rid of dust, and hot air out from top. Trouble gives a sound advice.

I've thought about building a computer inside a small fridge, style minibar, to keep it cool and quiet. But the condensation would probably be a problem. One engineer, asked what he would do to control both heat and noise, said: "I would sink the computer in a barrel and fill the barrel with concrete. MASS transfers heat, and MASS prevents noise."

Go figure?
