Thank you. Yes Prime 95 passes. It is a good advice with power supply.
But first I have to check my HDD, because I have a strange noise from the case - something metal - like to knock slightly something metal for short. I had this noise before to start receiving blue screens. Unfortunately Seagate tools doesn't find my HDD and I canít' start it. I am trying to resolve why and if I couldn't, I will check with something else. Give some advice if you know why sea tools doesn't find HDD or with which program to check my HDD.
About RMA CPU. I like to do that, but I don't know how to prove that there is a problem. They will take the CPU, they will test with Prime 95 and there is a no problem.
Thank you in advance!
