I have a Intel Core i7 system. I had tried first time to overclock my system but could not get success in that. I had planned everything properly to overclock the cpu. But before that my friend recommend me to first run a test to check the system stability. That really does not worked here. I was directly going to overclock the system. But this test has created a doubt in my mind that if I do the system without proper indication then that can crash my system. What you recommend for that. How can I then overclock the system.
