I have got a computer that turned off and now will not power back on. when i press the power button the light on the front comes on and the internal fan spins a tiny amount and then nothing. all connections are good.

am i right in saying its the PSU?

Perhaps. Quickest way to check is to swap in a known good pw supply. You do not have to fully install the test unit; simply connect the atx, aux, and video pw [if used] and hit the ON button. See if the mb will post. If it does then shutdown and install a new quality pw supply. If it does not, then you will need to do further troubleshooting.

check the listings in the bios for 12v line voltages and temperatures and post them

[How is he meant to get to the BIOS if his PSU doesn't work?]

it's a generic reply

would expect common sense to prevail

If it's the Packard Bell listed in your computer specs then the power supply is likely. You can try and remove the CMOS battery for 5 minutes, replace and see if it powers up.
