I was playing MineCraft and all of the sudden my screen goes glitchy and I crash, I waited a few minutes the held down the power button till it turned off. Then I waited another minute and turned it back on. When It came back on it wentwhite and stayed white, and it has like glitchy spots all over the screen

I need help figuring out what I need to replace. My first thought was to replace is the graphics card. But then my dad said before u waist money go ask someone.

If it shows some glitches even before the Apple logo. Then I will say most likely the GPU is faulty.

Anyway, can you hear the boot chime?

If yes, then the logic board, CPU tray, PSU, etc should still working.

If no, then you can try to remove the graphic card to confirm if GPU cause the issue. The cMP can boot headless without the graphic card installed.

or the cable or the monitor. Try plugging in another monitor to confirm/deny.

Basically agree, but IMO, not very fit OP's case. Cable or monitor failure should not cause the computer crash.
