A couple days ago i turned my computer on and all of the sudden multi colored lines stretch out across the monitor. Now every time i try to turn my computer on the monitor gets not signal.

I have tried to replace my graphics card and i have also checked that my monitor still works.

Try swapping the memory stick and clean the golden bar of the ram with a clean cloth. If that doesn't work try to reset the cmos battery (google search on how to do so).
