Won't post - HELP!
Last response: in Systems
Hello,
I just replaced my E8400 CPU with a new retail Q9400 and now the computer won't turn on. The red LED on the mobo is lit. When i press the power button the fans spin for half a second and then it shuts down again, no beep. I have tried clearing the CMOS with no luck. I have tried running the machine with only one stick of ram, swapping the video cards etc, no luck. Help!
MSI P7N Diamond 780i SLI
Intel Q9400 @ 2.66 GHz
Corsair Dominator DDR2, 2x2GB
Leadtek 8800 GT x2
Corsair HX 620 PSU

Whenever you upgrade, and it doesn't work, the first thing you should do is return to the original configuration.
Make sure it still works. If it doesn't, troubleshoot that first.

OK yep sorry i feel rather n00bish now, it works fine with the old CPU. So either the new CPU was DOA or it is not compatible with my motherboard. I checked and MSI seem to claim it is supported. I flashed the BIOS to v1.4 before installing to ensure that it was supported. Perhaps the problem is that my motherboard PCB is only 1.0, not revision 1.1. I'll have to grill MSI about compatibility and if it should be supported then I guess the CPU must have been DOA. Unusual for Intel though isn't it?
