Power Supply or Video Card Problem

I recently bought a new video card (Sapphire x1950 pro) this card replaces my 9800xt.

As soon as I finish installing the card and powering up my system;;; i found some problems that I found:

1. The booting logo was multi-color and with distortion, as soon the windows logo appears no problem at all.

2. 3dmark06 has distortion in the right corner and below. In 3 test I only have a blank screen. (I think is just the driver)

3. If I try to over clock the screen start blinking ( I am using the 7.4 driver to over clock).
If I over clock the minimum I still have the problem.


But if I play I don’t have any problem at all I played BF 2142, Oblivion, Half Life 2, Far Cry. All the games run great with out any sign that something is wrong. The video card temp is about 44c to 55c max. Also I don’t have any problem running 3d mark 2000, 2001.

:!: I will like to know what you think the problem is.

My power supply is 480w. I think that the problem is a combination between power supply and the new driver.
