The PSU to which is 350 WATTS is borderline to supply enough output to satisfy the graphics card and the other peripherals you have installed in your computer.
As dc3 stated above, your graphics card requires 300 WATTS minimum from the PSU.
Minimum means it will work with 300 WATTS, but with possible limitations and will run at a bare minimum.
Now, taking that 350 WATT output that the PSU is supplying, this has to be shared with the other hardware you have that is also drawing off of that 350 WATT output.
If for sake of argument, your PSU is outputting 350 WATTS, your Video card is drawing 300 WATTS, this leaves 50 WATTS left for your other hardware to use.
Competition becomes the result here, each piece of hardware starts fighting over the remaining 50 WATTS.
Something has to suffer here.
When one piece of hardware wins out over the others and it is the graphics card that suffers, your video will freeze up.
If your video card wins the battle, something else in the system has to suffer.
It actually becomes a catch 22 situation here, it becomes a win and lose situation at the same time.
When video cards with a rating of 300 WATTS are installed, a PSU that has a 500 WATT output rating is the bare minimum requirement. Provided you do NOT have a lot of USB devices drawing power from the system.
Hope this helps.
