Help please. PC won't boot

[NoustieChris]

Need a quick bit of advice on what's died in my PC. Getting power through the mobo for peripherals, but no hard drive or cpu fan activity when I try to power on... Is it a) borked mobo, b) fried CPU c) dead hard drive?

Should add it's a brand new PSU in last week.
