Error 90d and purple screen

[stmkmr1]

I have hp pavillion 15 e024 tu with windows 8.1. My laptop was slow and got message,

"The system bios has detected your notebook PC was placed in hibernation to avoid overheating .

The system is now operating normally and your data should remain intact.

 Overheating may occur if the cooling vents are blocked or the operating temperature exceed the specification. The notebook PC should return to normal operation once the situation is resolved.

 System Temperature (90D)"  

So i cleaned the fan and sink, changed the thermal paste and updated the BIOS. Since my laptop was slow, therefore i installed chrome os (removed the windows) from neverware. After doing all these things, again it was showing error 90d many times. But next day it was not showing any error 90d at all. But evening of that day, my screen went purple. And then next of that day, screen also become good.

Please help, what is the problem?
