Not natural buzzing sound, shutting down while playing or doing nothing...

[Eimatam]

Hello forum ! First of all I'm writing this article on the same computer that sh** is going on.. So it likes to shutdown itself whenever he feels like so, so if I lose my mid somewhere here in this thread, just skip that part... So everything started from my dekstop shutting down after being idle 1+ hours... There was no problem with that I mean it only pissed me off when I was trying to download something bigger or so... Afterwards it started to shut down if it was idle more than 1 minutes, which was/is something very irritating... Let's say I log in to my pc then I go to drink some coffee and my pc is down when I comeback and so I need to wait again for it to turn on... (Note: If I leave it at log in page, pc can stay up to 2 years and it still wouldn't turn off.......). Afterwards the buzzing sound started to come from my pc if it was AFK more than 2 mins and didn't turn off yet. WEll ok I mean it's nothing still, just keep computer active and everything is ok.... Then the new stage came on... If my pc was 100% it would start the buzzing sound and even if I'm using it, would turn off... Then I started to look for a problem and I found out about dgen.exe which pretty much destroyed my CPU usage, it was always over 80%-100%, so it would make CPU 100% all time I use it... So now I started turning off this program, everything was fine (except that buzzing sound coming off sometimes and computer shutting down itself after 1 minute).. But then... Everything got even more worse, I used this computer to play games like GTA 4, Battlefield 3, it was working at lowerst graphics not bad, but now... I can't even play league of legends or the simplest europa universalis 4, it would just start buzzing and turn itself off again and again... (Side note: I turned on task manager to see what happens when I play games because I was thinking that somekind of program is using the CPU again... So I started a league of legends game and started hearing that buzzing sound, I fastly went down with my windows button and saw that the game is using 75%+ CPU and after 1 sec it changed to 06% CPU and buzzing sound was gone, so yeah... What the fu** is going on here ? (but today even with 30% CPU usage it would turn itself off and buzzing sound would show up before it happens)

TL;DR
1. My pc is letting out somekind of strange buzzing sound, which I wouldn't call natural (Let's say wind's noise is natural and the dishwasher machine's beeps aren't..)
2. If I turn on game like league of legends or europa universalis 4, pc is starting to buzz and it shuts down after 1 minutes ( making it impossible to play games on it)
3. PC only turned off itself when it reached 100% CPU and stayed there for more than couple of minutes, but now it might turn off just at as much as 30% CPU...

Could you please help me to find the solution or at least where do I need to search for it, what's the cause of this thing,,, Thank you

P.S I cleaned out my computer's hardware as well as the software, fixed the registry, defraged everything as well and scanned for viruses which a lot of anitivirus programs or sites that does it

Make sure the fan on your power supply is working properly. Also, check your CPU temps.

Power supply's fan is working properly, CPU temp is 62 C, sometimes going to the 73 C, so I started the computer, checked where the sound is coming from and it was hard disk, from there the sound is coming and it's rather very warm, could that be a problem ? But if it's a problem, how can HDD's failure immediately make whole computer go off like cut down all electricity.. (That's probably for my knowledge more 😛) Should I try to fix it somehow or there is no other option than buy new HDD ?

Those temps are too high for your CPU.

Great ! Tho I already knew that... I'm searching for solution to fix it, so still has it anything to do with HDD or only with CPU ? And what should I do to get rid of these errors (I have some budget to replace them, but it's really small one and I need to know for sure which one to replace, thank you

 

[logainofhades]

The shutting down is most likely due to your CPU overheating. An inexpensive solution would be replace the cooler with a Coolermaster Hyper TX3. http://pcpartpicker.com/part/cooler-master-cpu-cooler-rr910htx3g1

Thanks ! Now.. Could I ask why the fu** does my HDD buzz in that kind of way ? Is it related with CPU overheating or it's a different kind of story ?

Edit: + What could be the cause of this overheating ? I mean I used this computer over 1 year with no problems, only now this kind of stuff is happening, I forgot to mention that earlier probably, maybe it would fix the solution, as far as I'm not sure if the simple fan would help with this... Isn't this problem in the CPU or HDD itself ?

The hard drive could be giving you issues as well. Many do make a buzzing sound when spinning though. Not as loudly as say a DVD drive, but they do tend to make some noise when going full speed.
