System crash in games

[Andrei Haiu]

Hello friends,my name is Andrei and I really need help with my computer.Let me tell you my specs:
-Intel i5 4670
-EVGA GTX660Ti 3gb edition
-2x Corsair Vengeance 1600Mhz
-Motherboard Gigabyte B85-HD3
-550W Power Supply(it's not a known brand,even I don't know it's brand,I remember it was 50euro)
-1 terra HDD Samsung (its kinda old and almost full of games and programs)
-120gb system HDD(old too)
-Windows 7

And now the issue:
-Everytime I play a game like Battlefield 3/Cs:Go/Medal of Honor Warfighter and games that require alot of resources at max graphics, crashes all the time.
-I get into the game and play a bit then my computer crashes,not normal but first it cuts off the sound then it shows an image with a desired color (sometimes blue/black/purple etc.) and i can't do anything just to shut down manually from the power button.
-Ofcourse in event viewer the error is kernel-power cause I kinda shut it down from the power button.
-I put my computer to a stress test(everything is ok,no errors tho' , it didn't even crash in the power supply test and cpu and gpu was max use!).
-The 1Terra HDD is making weird sounds and so does the system HDD.
-I had a computer before in which I had the 1terra hdd and I couldn't install games(tomb raider/dead space 3/Bf4 etc. pirated games [didn't had the money to purchase them] ).
-The error of the installation was that it said corrupted files(not all but the big packages).
-The thing is that my friends could install them(same source same games).
-People told me to run chkdsk on the 1tb hdd but didn,t had time to.
-Sometimes when the hdd stops making weird sounds suddenly,the entire system freezes for 30sec-1min-2min and I can only use the cursor.After it works again he sounds are back.(the sounds of that are kinda usually,without them I am pretty sure it gets stuck.

So now I'm guessing it's because of the 1tb HDD.If someone can help me in any way is appreaciated.
My toughts are to defrag the hdd then run error checking.
Also I checked the ram sticks and got no errors.The supply didn't crashed in the stress test.
Have a nice day!Regards,Andrei.
-Oh I forgot to mention that everything is installed on the 1tb hdd and the windows and drivers and programes on the other one(the stress test program OCCT is installed in the system hdd also)

Do you hear a buzzing noise when it crashes to a solid color?

Thanks for reply.
Not really,it sounds like the headset gets unpluged like a scratch or something,I had 5 sound drivers and disabled the ones i dont need and only used one,still crashed.

It kinda sounds like the driver is crashing for you video card. I've had that happen to me and its usually a solid color screen with a buzzing noise. Try using an overclock program to reduce your core and memory clocks by 25mhz. Afterburner is a good one.

 

[Andrei Haiu]

I'll try to lower the memory clock and core clock and see if still crashes.

 

[Andrei Haiu]

Also I will install a game on the system hdd and I will disconnect the 1tb hdd and see if still crashes,it might have a virus or something cause I didn't scan it for some time.

Update 1:Alright, I unplugged the 1tb HDD and I played the longest time but at a point my monitor went on sleep (I could hear the sounds of the game in the background) and then it came back up with an directx error ,something about my graphics card that didn't had any memory left and is required at least a 512 mb card to play the game.I just played MOH:Warfighter at full settings for 20 minutes in 60+ fps and at a point came with a directx error.Now I am trying to lower the base clock with afterburner.

 

[Andrei Haiu]

Update 2:I lowered the GPU base clock and memory clock with 25Mhz,and my monitor is going in sleep mode whenever I get to play the game and the game crashes.After I lowered the clock I didn't got any error with directx as I did last time.At this point my thoughts are that the PSU is not holding the components too well and makes my monitor to go on sleep.Any help is appreciated.

I found out the PSU is Inter-Tech CP550W,I don't know it's true power,if it can hold them or not, but any advice would be good.

550W is plenty to run a single card. I've never heard of that brand either though.
