I have a Lenovo K320 desktop.

Came out of the box with:
Intel® Core™ i7-870 Processor ( 2.93GHz 1333MHz 8MB )
ATI Radeon HD5570
8 GB PC3-10600 DDR3 SDRAM 1333MHz
1TB 7200
280W Power Supply

I wanted to beef up my gaming so I got a new GFX card which required a new power supply. I upgraded to:

500W Rocketfish Gaming Power Supply
Radeon HD 5750

Took a bit to configure my display but its now showing right at 1920x1200 on my 23" tv.

Now I do run into occasional problems. I can run games FLAWLESSY awesome better than before. My problems come when I do video editing.

If I record some gaming with Fraps at full screen and go to even just WATCH one of the videos my PC locks up and I have to restart it via the power button. Same things happens sometimes when I record at HALF screen (ends up with 960x500 or something video) and when I go to edit the videos in Camtasia studio my pc will just lock up and freeze completely.

I could edit videos JUST FINE before I upgraded with no lock ups. My pc should be able to handle this. Especially even better now. any ideas?
