Help! Dead mobo or dead PSU?

  rickf 20:54 03 Jan 2008

Hi All,
My son's comp was overheating and crashing so I bought a new case with a 500w PSU.
After transfering evrything onto the new case nothing happens when I press the power button. How do I know if I had killed the mobo during the transfer or the PSU in the new case is DOA? Pls, any suggestions will be gratefully received. BYW, I have turned on the switch at the back of the PSU before trying to pwer up.

HI, That's what I thought was wrong but have tried various combinations and the thing is as dead as a doornail? I think I have got it right though, the connections that is. Any other suggestions?

Anyone with ideas? Thanks

The only thing I can think really it to double check all the connections and make sure everything is seated correctly Graphics CPU Ram ect.

There is no power at all. Its not a booting problem. Does not even get to that stage, but yes I'll check everything again> In the meantime if anyone can help I shall be most grateful.

A PSU tester may help identify a problem click here

Maplin Electronics stock them as well

try putting a screwdiver on the two pins that are power pins on the mobo, do not hold them on as it will shut back down. just touch both at the same time, as the power button may be faulty
