Monitor goes Purple and flickers

[alexakis99]

When i was playing,after some time the Monitor went purple and some weird colors were moving around very fast.What is the problem and can i do?
Do you think that i from unlocking the fourth core of my AMD Athlon ii x3 450?But i wasn't having unlocked the core that time.

what is your gpu and your other system specs?
what is your monitor?

also since you have unlocked the 4th dormant core of your processor...don't forget to run a stress test on it.
use prime95 for a couple of hours.
