Installed Core 2 Duo now no power. Back to original works fine
I have just tried for the second time to upgrade my Core Duo iMac 20" to Core 2 Duo using a
When I try to turn the machine it the power light blinks on for a few seconds, then all power is lost.
I have tried a T7500 and an E8135
I can put the original processor back in, and everything works fine.
I have tried this with 2 new processors but the same issue each time. And original Core Duo works fine.
Any thoughts please ?
Is this a good question?
