Computer freezes when playing games after installing new graphics card

[sgplay164]

Hello, not so long ago I received a Lenovo GTX 745 from my friend, after installing it, playing most games (if not all) end in a crash about 15 minutes into the game, and I talking about a complete freeze as there is no sound, the screen stays the same and the only option is to turn-off the PC. I also discovered that when the freeze happens, all the components run at the same speed (as I can't hear any changes in fan speed) as before the freeze, and they continue to do that until I turn off the PC. The main reason why I'm asking for help is because when I take the GPU out and start using the integrated graphics everything works fine, obviously at lower frames so experience is much worse but at least it works. The GPU works fine on my friends PC.
My Specs:
APU : AMD A8-7600
MOBO : Gigabyte GA-F2A78M-HD2
RAM : 8 GB (Single channel)
STORAGE : 500GB HDD x2
PSU : EVO Pentium p4 (Model : E - 600BR) 600W
(GPU : Lenovo NVIDIA GTX 745)
OPERATING SYSTEM : Windows 10 64 bit

If it were me, I would try a new PSU. I haven't read much good about EVO PSUs.
