I am using ATI Radeon 9550V+ and after I insert the GRAPHIC Card the screen got a little out of colour.Please help me!Read the MANUAL that came with the VIDEOCARD, but I'll save you the hard work of opening all the little booklets that probably came with it.

You're going to need videocard drivers, obtain them at ATI its website I  am using a Window Xp and a pentium four processer.But after following on what you say,my computer still went out of colour.I remember a cheesy old movie where Count Alucard turned out to be Dracula. What a surprise. 

Please post the link where you got the drivers.

Some info about your other hardware could be important. You also could have gotten a bad card or this could be a pepcak.pepcak?  I believe GX1_MAN made a typo error.  http://en.wikipedia.org/wiki/PEBKAC  or PEBCAK Yes, I know what that means. I thought he made up something himself.  OK I will give you more details it is a Pentium 4 Cpu 1.80GHz and has 224MB of ram.The original manufacture of the graphic cards is SIS.Hope this will help if not,tell me in more details.
Run Everest, make a report and post it here. You may WANT to print out a report for yourself as it will tell EVERYTHING about the hardware you would ever need.

(Raptor, yes, that was meant to be pebcak. My coffee had not been absorbed this morning at that time.)It's probably not the lack of coffee, but the coffee it SELF.. Junk food. Can anybody teach me how to use Everest to check my graphic cards Please Install the program and let it create a report...save it as a txt file and post the results here.

It may take more than one post.
