Solved How do I fix the colour of my computer?

Specs: Windows 7
I recently had my computer repaired at a reputable store. The reason I needed to get it fixed in the first place was because we could not load windows 7 (our operating system). We would turn on the computer and it would go to a blue screen and say that there was a fatal error and windows could not load. It also said that we had recently downloaded something that caused the crash and that we needed to remove it but we could not get into the operating system to remove it. We are just barely able to use a computer so the thought of using anything on the computer but windows is far beyond our capabilities. Before it broke the picture was fabulous, we got an HD screen and everthing looked like real life. The colours were vibrant and picture perfect. Now it is all the wrong colours. No matter what I try in the catalyst control center or on my monitor, it will not go back to being as good as it was. Should I be suspicious that the tech that fixed it removed my old video card and replaced it with a crap one so I'd have to go back to get it fixed again? How do video cards break in the first place? The guy that fixed my computer said that the ram was shot and needed to be replaced. I admit that I have just the faintest idea of how it all works. He said that he wiped the computer out to factory defaults but this is not what the colour was like when it was new. There are also now files on my computer time stamped to the day he fixed them that I cannot get access to, is this normal?

I have a gateway and if someone can tell me where to find the information you need to help, I'm all ears.

Assuming the video card is the same, the usual reason for bad color is the video drivers aren't installed. If the repairman reset it to factory specs that should have included the video drivers as well, unless you installed a different card. Anyway, if there's a problem with the drivers it should show in 'display adapters' in device manager:

What adapter does it show there? If it's showing some generic adapter--standard vga graphics adapter--then it's the drivers as windows has set up on basic video support because it doesn't know what you've got.

But if everything shows OK there maybe you just haven't adjusted the colors correctly. You mention the 'catalyst control center' which I think is provided by AMD for their adapters. I can't tell you how to use it but it sounds like you're familiar with it anyway. You can also adjust the color from windows' screen resolution. There's a little tutorial here:

If you get their stupid 'suspicious activity detected' warning just go ahead and fill out the information so it will continue.

I agree with Dave that it is probably either an incorrect or missing
driver or an incorrect adjustment. My monitor has a whole bunch
of adjustments, and it isn't entirely obvious what they all do. The
Catalyst Cotrol Center also has an awful lot of hard-to-comprehend
adjustments. The last time I re-installed Windows, I just installed
the driver and not Catalyst. Your needs may be different from mine.

Did you send the monitor to the shop with the computer? Have you
ever used the monitor with another computer? If you have another
computer or video source available, you could test to see whether
the problem still shows up with the other source.

If the driver is correct and you can't find any adjustment that fixes
the problem, you could remove the power cord, open the case, and
remove and re-seat the video card, maybe cleaning the contacts
on the edge with a pencil eraser, and blowing any dust out of the
socket with a can of compressed air. Did the shop say they cleaned
iinside the case? I don't know if that is standard proceedure or not.

How bad is the color? If it is only a little bit off, then it is less likely
to be a hardware problem and more likely to be either the driver
or an adjustment.
