Randomly screen freeze

[propm]

Okay, so about 1,5 year(s) ago I build my self a budget "workstation"/gaming computer, just enough to render videos, 3D models etc.

 

Here are the spec for the initial build:

MSI 970 Krait edition am3+

FX-8370

1 TB 7200 rpm WD

5 fan(was going for 2 + cpu cooler, but when I bought my cheap tower it said in the description that there was none included, there was 3..... )

hyperX 8GB x1

Crosair 750w PSU

Asus GT 210

 

I had issues right away with freezing, How ever this was fixed by turning down dram voltage a bit, then I had no issues in about a year.

during that year I had installed a borrowed R9 270X 4GB from Asus, and two balistic 4GB x2 on the second channel.

all off those parts was installed long time before the issues came back to life. 

What happen prior the the issues coming back was a problem with screen being totally black, so I reset the CMOS, and then every thing worked again, shortly after that

my hard drive gave up on me and I installed an old Samsung 840 250GB that I had laying around. 

the problems started right before the HDD gave up on me, and continued afterwards, I tried to repeat the dram voltage thing with no success.

 

Also, on the SSD I started getting errors like x0000x00 and such, and suddenly I could not get back in to windows so I was forced to reinstall windows, but this time WIN 7 because free Win 10 was not available any more.

System seemed a bit more stable, but still froze, Than I tried to use a different graphics card, both a GT 210, and a GT 480(I think). I tried to use only one of each RAM, I tried a different FX processor, 6somthingsomthing, and I even tried a Athlon processor, no luck there either.

So I thought to my self " I have had it!" And I called a friend who kindly borrowed me his old computer parts, and I changed the mother board to a P50Q or something like that and a Intel Duo 2 Q6600 and two ozo DDR2 2GB sticks.

And just decided to format and install win 7 again. This time 32Bit because for some reason I did not get the 64 bit to work. 

Any way, it seemed stable, until today when the computer froze again, same symptoms, monitor showing last image that was on screen and a horrible sound from what ever audio/music that was currently playing.

 

So, Basically I tried to change every part possible with the exception of the PSU, might that seriously be the cause of my issues? I never had issues with any of my PSU's before, seems odd to me.

I am no genius when it comes to computers, I can build them, usually repair them and use them, how ever, I never try to change thing's if it's working, I never overclock or any thing like that.

That's why I am asking you folks of LTT  a lot of you guys/gals are freaking geniuses when it comes to computers, so I hope to get some useful insight to my problem.

 

 

Also, I am very sorry if my text is tiresome to read, I'm not very good in either English or my own f-king language.

With that I mean that I got  3 in English both oral and written, 3 are approximately equal  to D. 

 

Thanks for help in advance
