Installed new Graphics card-> screen color is all wrong

That PSU is a POS completely mate whether you want to believe it or not.

Under ATX design standards that that PSU conforms to, 12V+1 is dedicated to the CPU and any excess amperage potential cannot be accessed by the rest of the system. This essentially means your PSU can provide a maximum 25A to run the 4890 and the rest of that relatively high end system (minus the CPU).

You are underpowered. If you choose to ignore this advice that is fine, but at least let us know if your PSU goes pop and takes a CPU, GPU, RAM etc with it.
 
so you´re saying I got to get a different PSU? Do you have any suggestions? (I´m computer challenged).

Let me see if I got this straight. The PSU is underpowered, and is what causing the color issue, and may also have a serious negative affect on other hardware?
 
If your card turns out bad or not, you need to replace your power supply on that system. That Chiefpoop will end up making a big mess on you and taking stuff out with it.
 
I've had a similar issue before once upon a time. It turned out that my video out cable was a LITTLE loose in the plug. If I tightened it JUST right the third color would come back. I wound up switching monitor cables to get it to be OK without worrying about 'bumping' it and screwing it up. Be ABSOLUTELY TRIPLE sure that the plug is in perfect (try shifting it around a bit while watching the monitor for color). If that fails, try the other video out plug/and or a new cable.

I've checked around on other forums, and they give me the same reply as you do. I have a relatively old (2000, 2001?) hpL1925 flat screen, 19", and what the others tell me, is that the cable itself is too old, and that the use of adapter will screw it all up. I think this sounds reasonable compared to the power supply, even though I haven't ruled anything out yet.

I will take some pictures of all the possible areas where there might be something that may go wrong. I think that is the best way for me to illustrate what kind of hardware I'm using since I'm not very "into" all this VGA, DVI and so on :P

I agree, but that's another project.

That's yet to be confirmed. ;)

To the OP, do you have or can you borrow a multimeter? If not buy a $10 one and we'll do a test under load of that 12V rail. I would be interested if under load, and temp, if that PSU is struggling. I would suggest it would be pushing it, and underpowered GPUs frrequently display similar symptoms.

It would be interesting to see that rail voltage minimum under full system load.
