Colour looks 8-bit

Depending on the inputs on your projector and the outputs on the Macbook, you'll need to pickup one of a few adapters.

Try having your colour depth at 32 bit, right click on your desktop and goto graphics properties and select 32 bit instead of 16bit

Please go to menu and check auto power on if it is on make it off

The color bit depth is controlled by your PC Video card, monitor will show what it is being fed with. Please check to see if you have correct video card driver installed in your PC and the video card has enough memory to provide the 32bit color depth.

It appears that your video card does not support that resolution and color depth. If you've installed all of the proper drivers from the manufacturer, re-check the maximum specs - sounds like you're looking for HD (1080) and the card can't deliver in full color (32 bit).

Sounds like your colour settings are wrong. RIGHT click on the desktop and click properties. Click the last tab which is display settings or settings. Check the colour is set to 32 bit as opposed to say 16 bit or 256 colours. If you post specifically what OS you're running, I can probably offer more in depth help if this doesn't suffice.

you can set the color depth in your display properties->settings->color quality select 32 bit. if still don't work. reinstall your video card driver.

Your colour issue may be down to incorrectly configured graphics settings, make sure in properties the colour is set to Highest (32-bit). If that fails, you can use a new user account, drag your files over on the new account and re-do your settings and delete your old user account. As you have changed quite a lot of components in your computer, the only likely problem left is either a dodgy power supply unit or an overheating issue. If a power supply detects it has a fault, it will shut itself off. However, go to your BIOS and search through menus for temperature information (you can usually find it in the power section of the BIOS) and check if the temperature is abnormal. Anything like 75 celcius and above can cause the computer to shut itself down as a safety feature. On most motherboards, you can raise this limit so it shuts down at 80 celcius or 90 celcius, or not at all. 80 is the absolute highest I'd ever set a computer at, because the higher the temperature at that sort of level, the lower life expectancy your components will have. You may also have a faulty CPU as "compileing and writing DVD's" is very CPU intensive and can be causing the computer to die. Make sure your CPU is NOT OVERCLOCKED. If it is, take the overclock off.

I had the same problem I replaced the motor/lense cover unit at the cost of $AU140.00 and that fixed it.
