Screen goes black and my fans turn up as fast as they can go.

[KingLira]

So the other day i was play some Cs:Go and i had been playing for and hour or less then out of nowhere my screen turns black and my CPU fan turns all the way up. So i thought it over heated since one it was almost 90 (Fahrenheit) degrees outside and my room was pretty hot even with fans. so i went to Fry's to pick up a CPU fan but they didn't have the one i want so i deiced to order it online since can go a few days with out gaming anyway but i did get some case fans to help out while i do homework and stuff. Then today i was looking online at other CPU cooling options and wouldn't you know another black screen and fans jump up to top speed again! and my temps was about 40 degrees (Celsius) some times 50 today and its like 60 (Fahrenheit) outside my room is very cool as well.

So now im not even sure if its my CPU. has anyone ever had this happen before? How can i fix this?

If the screen goes blank, this suggests a video card issue. I would recommend downloading a temperature monitoring app like this:
http://openhardwaremonitor.org/

Report what your CPU and GPU temps are when idle and when gaming for 10 minutes and also check what percentage of "load" they are running at.

Also, are your video card drivers up to date? Having the latest drivers can be crucial, especially for gaming.

Will try this but have a question should i leave the Monitoring app running while i play the game or play the game then start it after 10mins? Also im not 100%sure how to read this so do you want the CPU total load or each one? Same with the GPU do you want all of them or specific ones? Sorry have never used anything like this before. Also i like your user name lol

wasn't sure what all you wanted so i just saved a txt fail for both and yes my drivers up to date.
