Intel Xeon E5-26xx - Slow PC

[arodi007]

My current spec:
Motherboar: Intel DX79TO
RAM: Kingston DDR3 2GB(1 slot)
HDD: Hitachi 500GB ATA 3Gb/s
GPU: Geforce GT 620(2GB RAM)
CPU: Intel Xeon E5-26xx
PSU: 500W
Fan system: Zalman CNPS12x
OS: Windows 7/8.1 64

My is running slow even in BIOS menu(screen fade up/down and take 2-4s to act). When I restart, its often shutdown.

I have run Intel Desktop Utilities and show
Processor Temperature: 70C
Processor Core 0: 28C
- Core 1: 29C
ETC.. (vary from 28 to 34C)

Using SiSoftware Sandra

Board Temp: 70.0C
CPU Temp: 31C
CPU 2/AUX Temp: 70.50C
ICH/PCH/Aux 2 Temp: 70.0C
MCH/Memory board Temp 2: 0.5C
Inlet/Outlet PSU Temp 2: 36.5C

I can't figure out if the processor is damaged/ incompatible or just a bug in the bios/cooling system(I tried to reduce speed of the fan, the package temp remain 70C with turboboost disable).
When converting a video/extracting/installing, the CPU usage is less than 40%.On idle 0/1%.

If the CPU is running at 70c at idle then you have bad cooling or bad thermal paste. You need to check that. (But cores at 29 are fine, i dont know why the CPU says 70 and cores 28).

Maybe your CPU is throttling down because of temperatures.

But your PC running slow on BIOS menu that's certainly not normal.

I have updated the BIOS, still the same.
My CPU is an ES, is that causing these issues ? since its series is on the list http://processormatch.intel.com/Processors/CompatibleProcessors?componentName=DX79TO
It should be compatible else it won't boot or start. ??

If it wasn't compatible it wouldn't start. So that's not the problem.

Check for bloated capacitors, scorch marks, grey matter on chips, do a memory diagnostic, touch the main chip when running to see if its hot...

You have an ES chip. Some of them are essentially unlocked versions of the retail chips and others are various kinds of "not quite finished yet." Some can be extraordinarily buggy. That would be my first hunch as to what is goofy with your system as normally servers are rock solid reliable as you get. (I know, I have three of them.) We'd need to know exactly which ES you have, which would mean you need to tell us the Q-spec number on the top of your chip and what the CPUID shows as your family/model/stepping.
