The following is a,, inconvenient problem that could be an issue with graphics cards other than the ATI 5970 card used in fast booting computers and may actually be a power supply problem. I posted this wondering if others have this problem and would like a work around.

The problem: When starting the PC normally after it has been off for several hours, (everything is at room temperatures), within a minute or two of it reaching the desktop state, the display will display a random noise of pixels then shortly after that the system will reboot. (Sometimes the system will be able to restart the driver an all will be fine after that without having to auto-reboot.) After the rebooting, everything will be stable. If you check the Event Viewer, in short it will show the video driver had crashed. (I do have a work around for this problem and I'll say that further down the post.)

I've had this issue ever since a friend gave me his 5970 when he upgraded. Recently I upgraded the MB and CPU and still have the issue, so it's not a MS or CPU problem. This issues seems to be related to supply voltages or currents not being at proper operating levels when the video card demands them. (All electronic components are affected by temperature even voltage regulator components. There must be a period of time required, though short, for the circuits to stabilize even with temperature correction circuits. I know because I use to work with discrete electronic components.) (Note: the power supply I'm using is rated at 900 watts so supply capacity is not the problem.) Since my computer boots fast, this can be due to the video card's supply regulators not being at spec in time or the power supply not being at spec in time for when the GPU needs it. I say that be cause of my work around technique. Here is the technique that avoids the issue.

On cold boot up. I enter the Bios menu for a duration of 1 minute at least. I don't change anything. This is just a means to delay getting to the desktop state. My computer is very fast. If allowed it can get to the desktop state in 15 seconds. With the former MB it could do it in 45 seconds. Once I have delayed the boot at least a minute, I can finish the boot to the desktop state and have a stable system.

For me, this problem is not bad enough to justify replacing the power supply or Video card. I can live with forcing a delayed boot. But if some of you out there have this problem and MUST fix it. Replacing the power supply would be the fist step, then replacing the graphics card would be the next.

Any additional input is welcomed.

Solution
Try this, it might work.
First of all you need to TOTALLY remove all the old drivers. Use this link.

Note:
Select the respective company(i.e Nvidia or ATI) drivers to be uninstalled.
Use clean and restart option.
And then install the new drivers after rebooting.
