Color missing is usually
1. bad cable or cable connection
2 broken connector on the PC or Monitor
3 bad video card or monitor.

Neither RAM nor Drivers will fix this, not sure what smps is unless you mean "amps" as in your power supply.

Reseat the cable, try a new cable. Try the monitor on a different computer and try your computer with a different monitor. That will get you to where the issue is.
