Strange PC problem.

Hey guys,
I just build a new pc and here are the specs.
CPU: AMD X4 955
MB: Asus M4A78-ME
RAM: 2x 2GB OCZ Platinum 1066Mhz
VC: Sapphire Radeon HD4870 1GB
PSU: OCZ OCZ600SXS StealthXStream 600W
I have 2 screens a IBM CRT and a SAMSUNG 20" Wide

Here's my problem; When i turn on the computer or if i lock it and turn off the IBM screen the pc locks and the fan begins to turn very high..
But when i turn off the Samsung it still works fine.
I have both the pc & the screens on the same UPS.

Can anyone help me?

Is the VGA connected directly to a VGA port or to a DVI-VGA adapter?

NMT - Let's try something that appears to work with a number of issues. In Device Manager, uninstall your Video Driver. Boot if requested. Let Windows automatically install the "new" driver.

Dave Bowman: Open the pod bay doors, HAL.
HAL: I'm sorry, Dave. I'm afraid I can't do that.
Dave Bowman: What's the problem?
HAL: I think you know what the problem is just as well as I do.
Dave Bowman: What are you talking about, HAL?
HAL: This mission is too important for me to allow you to jeopardize it.
Dave Bowman: I don't know what you're talking about, HAL.
HAL: I know that you and Frank were planning to disconnect me, and I'm afraid that's something I cannot allow to happen.

is is connected to a VGA to DVI-D connector on the GPU.
And it does it when i boot the system too.. so it wont be driver problems.

However, it *can* be an underpowered graphics card since you are using a dual monitor approach....

Please clarify. Do you mean that you can stop at the BIOS screen, for example, and you can recreate the problem? If yes, the following test is valid and conclusive:

Remove the straight DVI connection. Leave the VGA connected. Does the problem remain?

If yes, swap ports. Does the problem remain?

If Yes, replace the adapter or the VGA cable.

If both are replaced and the problems persists, you may have a faulty* card, power supply, or PCIe port.

* Faulty to include out of spec.

Perform the above-listed actions and report back..
