I just oc'ed my q9550 and am getting direct x error after a couple seconds after launching my pc games and need help. I have a Asrock g41c gs motherboard and my cpu is at 2.4Ghz which is the max I can oc it. My cpu is 2.8Ghz and my motherboard has to oc to run my cpu. My FSB is at 1066 and it is running great but when I oc my cpu I got direct x errors. I hope you can help. I want to add I stress test my pc after I overclocked to 2.4 which is the max I can get it to with my hardware. The stress test was a good and I was ready to play games, it tested my cpu load at 100% and also my memory and it completed with no errors. I launched my first game which is Fortnite and it loaded fine, but in the main menu after a couple of seconds it would exit with a direct x error that says D3D has been lost. My second game I tested was Battlefield 4 and when loading a map it crashed with a direct x error also. I am sure it is because of overclocking my cpu because I changed my cpu back to the default settings which are 2.2Ghz, launched Fortnite and Battlefield 4, and joined multiplayer and it loaded the game and it worked fine on both games. Can anyone help me?.
