I have just upgraded my motherboard and CPU.

Asrock H77 pro4/MVP
Intel i5 3570
2* 4gb DDR3 corsair vengeance 1600mhz ram
GeForce 550ti superclocked
500gb hard drive with win7 64bit OS installed

I have connected the 12v 8 pin connector in conjunction with the 24 pin ATX power cable along with the Hard drive, CPU, cooler and RAM.

The result is the the computer fans switching on for approximately 10 seconds and then computer restarts - this is continuous until i forcefully shut the computer down.

nothing is displayed on the monitor.

Hi, The CPU requires a newer BIOS version. It might be that you should firstly use a supported CPU for flashing the BIOS and then use the i5-3570. Here's the Support List:

Unfortunately i do not have access to another CPU. Is there an alternative that i could try?

I can't see if the BIOS chip is on socket or not. If on socket, you can order one and easily replace it. If not, a local shop might help.

I have just noticed that there are a few slightly bent pins where the CPU would be placed.

Does anyone know if this could be the reason why the power is cutting out when i switch the system on?

Thanks in advance

Yes, bent pins will prevent computer from turning on completely and being function.
