Computer freezing help

I've had my computer since last march and I've had it formatted multiple times due to BSODs and freezes, after it has been formatted it works for while then the problem comes back. I've had it sent off to the manufacturer and they said it's not hardware but the upgraded my power supply from a 400 watt to a 700 watt. They also replaced the graphics card because the fan was making a noise, in fact they upgraded it from a GTX 650 to a GTX 650 Ti. Now it's something i'm installing but I can't figure out what it is. If you need anymore information then ask. I've done memory tests and stress tests so I'm 99% positive that it's not hardware but it's something I've installed but I can't figure out what. I'm quite confident that it's drivers.

Hey, Welcome to Seven forums.

When you say PC freezes, when does this happens? during games, watching videos or just like that. You also mentioned that the issue is due to drivers? Are you referring to GPU drivers? If yes, download the latest drivers from NVIDIA site and also download Driver Sweeper. Uninstall the GPU drivers, run driversweeper to clean the left overs of the drivers. Install the latest drivers now. Reboot.

Some hardware tests to run.

Graphics card test:
Video Card Stress Test with Furmark

Hard drive(s)test(s):

Pick one for your HDD brand or use Seatools.
7 Free Hard Drive Testing Software Tools

RAM (memory) test:

This will require memtest on a bootable CD or USB stick.
RAM - Test with Memtest86+

Suggest running sigverif.exe to check for unsigned drivers as well as updating any out of date drivers.

Start> Run then type

sigverif.exe

Press Enter.

If any unsigned drivers are detected post the results and someone will take a look.

Thanks for the reply.
It freezes when playing games, it doesn't do it often. I have the latest Nvidia drivers (not beta drivers). My experience with driver sweeper is horrible; when I've used it before it crashes on uninstalling drivers which cause my PC to freeze. As a result it causes lots of problems when I turn it back on so I don't particularly want to use it.
I've found computer freezing is extremely difficult to solve as there is generally no clue as to why it has happened.

It does not freeze, it merely stops responding for some time.

But, it will come back after sometime showing all the left overs of the driver. After you uninstall the driver and run the sweeper. PC freezing can be caused by driver clashing.

Run Windows Update with these settings.
