Tmaster, I am afraid to say that your motherboard and processors have been out of support since December, 2012
However, you can try testing the system out of the chassis with minimal configuration. (Motherboard, processor, power supply, 1 memory stick and video card) . Then add the hard drive were you have the OS install and check the performance of the CPU.
You could also download the "Intel Processor Diagnostic Tool 64 or 32 bit" . This diagnostic tool checks for brand identification, verifies the processor operating frequency, tests specific processor features, and does a stress test on the processor.
You can try to remove the CMOS battery and leave the system without it for about an hour. Then put it back on and restart the system.
