Have a Dell Optiplex 760 that is giving a 3-4 error code.
The manual for the 760 lists the error codes, but for the 3-4 error code, it would be accompanied by a steady green or steady amber power light. When 3-4 is flashing on mine, the power light is off.
Both 3-4 errors relate to the RAM modules, but I've tested mine (and others) and they're all ok, but the 760 still won't boot.
The PC did boot up yesterday morning, I had the OS (XP) and the acquisition software running (it's connected to a fermenter system), but when I came back to it to start the acquisition, the PC was off. I had a spare 760 that I was able to swap in to get me going, and since then have tried lots of things to get the faulty one going again, RAM modules, disconnecting drives/cards/peripherals, differnet power supply, but still get the 3-4 error.
Any ideas?
