unsupported cpu installed

[DjGeoX]

I have an HP p5 g5451sc PC with a Foxconn 2ABF motherboard. When I bought it it had the i3 2100 processor (socket 1155), these days I decided to upgrade it with an i5 2500k and the moment I start it with this process before the window opens "unsupported cpu instaled Pc will automatically power down in a few seconds. "If I press the f1 key at this time errors, my windows open normally and everything goes in normal parameters otherwise it closes itself. I want to specify that I have as a component: 1 ssd, 1 hdd, gt 730 2 gb video card 128 bit sddr3, dvd rw, and a 300w source (HP-d3006a0) What should I do to eliminate the so-called error?

Hello
the model should be confirmed
with what you indicated, I only find this:

Unfortunately the SSID of the motherboard is not given

Motherboard Specifications, (Cupertino)

but if it is correct it is mentioned:

• Socket type: LGA 1155
• TDP: Max 65W
• Motherboard supports the following processor upgrades:
  • Core i3-2xxx/T dual core
  • Core i3-2xxx dual core
  • Core i5-2xxx quad core
  • Core i7-2xxx quad core

your processor is therefore incompatible!
