Sorry, I should have proofread my post for the glaring errors. Thank you xaira fo pointing them out.
I actually have 2tb of hard drive storage and the video card is from ati. Silly me.
Anyway, when I am trying to play hi-def videos with Pixela software, which came with my Canon HD camcorder, I had no problems before. Now when the video starts up, the computer locks up and I have to hit the reset button to restart it.
Also, when I exit the computer for Shut Down, it restarts.
Thanks and any suggestions would be appreciated. I didn't have any problems when I had the other cpu's. I switched because the Intel i5 is so much faster than the others and I really like the quad.
