I wanted to upgrade my CPU on my outdated desktop (Dell Dimension E510). It currently uses a Pentium D 925 processor. I wanted to upgrade to the best CPU my current motherboard could support, and did some research on the matter. The motherboard is a Connolly E187242, and using Intel's website, I saw the best processor compatible with the 945g express chipset used currently would be the Intel Core 2 Duo E6700.
I went ahead and ordered one, installed it, and now the console just displays a solid amber light (Dell says: The Dell Diagnostics is running a test, or a device on the system board may be faulty or incorrectly installed). The green light on the motherboard lights up and the graphics card runs, and since it ran just before I replaced the CPU, I have to believe that is the cause. The screen also doesn't display.
Does this suggest the processor isn't compatible after all?
I'm not sure a bios update will fix it. I'm already on the A05 patch, and the newest one, the A07, only improves OROM initialization (not really sure what that means to be honest). I hadn't thought about the power supply b/c the processor uses less power than the original. I could give it a shot though.
