Danny, I would recommend you to try the Intel® Processor Diagnostics Tool to see if it shows up any error.
It is also important to run this utility using only minimum configuration, such as motherboard, processor, memory, and only the hard drive that has the operating system installed Processors — What is the Intel� Processor Diagnostic Tool?
Then, you can start adding any other component (one at the time). Please leave the video card to the end.
It is important to know that even though the stress test could be concentrated on the processor and the Memory Controller Hub, there are many other components involved.
I ran IPDT Diagnostic test - now I would like to do an edited Test - to stress test the CPU and Memory. I tried a few settings but not having any luck - only 3.5 GB of RAM appears to be accessed out of the 16GB that my system has installed. Using Win7 task manager performance tab.
It reads all the memory - pass that test.
Memory alloc - doesn't appear to use all my memory (not sure)
Any help would be appreciated.
Danny, at this point what we can do is test the CPU on another compatible motherboard, just to verify if it is or not defective.
If you want you can contact our tech support department in order to replace your processor. http://www.intel.com/p/en_US/support/contactsupport
But before, please check with the motherboard manufacture if there is a new BIOS version available that needs to be install on your system.
