So I have an issue where my system freezes (hard locks) during two main activities. Youtube (online video) and games:
The freeze is a frozen screen that no matter how long I wait or what input i place to the PC nothing will change or unlock the system.
I can demand A freeze by starting to watch you tube - after about 6 seconds of viewing The System will freeze.
A freeze in inevitable whilst playing WoW though I have played for upto 2 hours with no interruption.
This started (Perhaps co-incidently) when I installed a new 7970 - However, with 3 different cards and fresh HDDs the freeze will still occur. PLUS I ran the card no issue on youtube on another system for 60minutes no issue.
Reinstalled windows - isolating and swapping boot drives
Swapped 3 different PSUs
tried 3 different GPUS (5850, 6970, 670)
tried new ram (kingston HyperX)
tried single drives (NEW drives)
tried 2 mobos
This has lead me to the only possibility that my CPU is to blame, However, I Have tested the fark out of it Placed on a 100% burn test for 10minutes an didn't miss a step - Did not even go above 50C - So how could it cause crashes?
