Windows Freeze Problem (Windows 7 Ultimate 64bit and Windows 10 Pro 64bit)

[Golub97]

I have a Windows Freezing issue here.

While playing games, doing skype video calls or just watching a video, online or offline, my windows randomly freezes. The picture freezes and the sound also, giving the awkward "dzzzzzzz" sound, I'm sure you know what I mean.
It all started after I installed a new Windows 7 Ultimate 64bit system. I had one that I used previously but due the error 0xc000007b error I could not fix I installed a new Windows. Althrought the error was fixed I started having this freezing problem. I tried several versions of Windows 7 Ultimate 64bit and all had the same result, I also went as far to upgrade my Windows 7 to Windows 10 Pro 64bit, and yet, the problem stayed.
I'm getting pretty frustrated at this point, because after a long day of work I want to relax at home playing video games and I can't.

My specs are:

Motherboard: ASUS M4N78 SE
CPU: AMD Phenom x4 9600BE 2,3ghz (never overclocked it)
Cooling: Cooler Master GeminII with 2 fans
RAM: 2x2GB DDR2
GPU: GeForce 730 GT GDDR3 128bit
OS: Windows 7 Ultimate 64bit SP1 and Windows 10 Pro 64bit.
Power Supply: LC-Power 600W LC600H-12 V2.31 12CM FAN
Storage: 1xSATA Hard Drive Maxton (I think) 80GB - This is the one I have my system installed on; 1xATA Hard Drive Samsung 120GB

I tried uploading my drivers and everything, they were up to date and the problem kept on.

If anybody knows how to help me out I'd really appretiate it. Thanks. :/

Try to use it without GPU and then try it out without one ram module!

Well I'd try try it without the GPU, but my motherboard does not have an integrated GPU on it, only the one I'm using. Should I ask for a new GPU of the same type? Since I have the guarantee still.
Also, I ran a memory check to see if my RAM is bad, said no problems were detected. Should I still try it without one or will this do fine?
