The setup..<br />
&nbsp; Fresh install Win7 x64 dual monitor setup on a Nvidia Quadro FX-580 with latest drivers.<br />
&nbsp; Dell T3500 with Xeon, 12gb Ram, Quadro FX-580 <br />
<br />
The error..<br />
<br />
When using a Win7 Areo theme the pc will lock up and show a pretty neat rainbow effect after a few minutes no matter if it is idle or being used. If i turn off the Aero theme the PC is fine till the cows come home. It just when i select a Aero Theme.<br />
<br />
I uninstalled the older Nvidia drivers and did a fresh install of the newest one's<br />
Same issue. Updated the Bios, chipset and just about every other driver avalable.<br />
<br />
Thanks<br />

A monitor or a display is an electronic visual display for computers, usually comprised of the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size. They are connected to the computer via VGA, DVI, DisplayPort, Thunderbolt, LVDS or other proprietary connectors and signals.

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.
