Hi,
I'm currently trying to fix a customer's machine which is having the above issue. A few seconds of being switched on, the machine switches back off and heads into an on/off loop.
I've tried the usual... CMOS reset, RAM, GFX, PSU with no joy.
I popped in an i7-2600 which fires up beautifully.
My customer mentioned to me (finally) that he had a similar issue when he built the rig, and that flashing the BIOS helped him at the time.
Figuring that this board has a dual BIOS, I doubled checked the version and it appeared to have reverted to the original (F8). The customer told me he thought he put in F15, which I assume is a guess, as the only BIOS available for this board is F18.
So, I updated the BIOS, but there is no change. The machine still dances between on and off with the customer's CPU installed.
One other, but possibly unrelated note, is that the PCI-E(1) port doesn't appear to register a GFX card fitted, that is, if I turn off the onboard GFX then the machine refuses to POST (with GFX error). PCI-E(2) works fine however.
Can anyone enlighten me as to what's going on?
Thanks in advance.
