Been having a bit of a downward spiral and just wondering if the motherboard is dead at this point. I'll explain.
Was upgrading an ECS GF8200a to a Phenom II x4 945 processor. I flashed the BIOS as required from their site to the latest BIOS to handle the CPU. Ever since then it's been one issue after another. It would hang and crash randomly to a white screen and after rebooting it would report a BCCode 124. It also started dropping the Networking out, going from connected to "no network available", and then crashing to white screen. I checked device manager and there were no errors.
I decided to try a clean install of windows 7 and had the same issues.
I started to wonder if the BIOS didn't flash correctly so I tried doing a restore to default from the BIOS with no effect. I also tried clearing the CMOS using the jumper. That turned out to be a really bad idea - I thought the machine was off (it had no power or lights on) but when I reset the CMOS and booted it back up it said that the settings had changed since it was in hibernation mode. I immediately facepalmed my stupidness.
Now the machine boots to the "Starting Windows" screen then hangs and the graphics go nuts, looking like an '80's video game. I tried using a Windows 7 repair disk and even booting from that gets a junk screen.
So, any ideas? is the BIOS fried? Hardware issue? I can't provide much in the way of crash reports as I can't get much past the POST screen. If the BIOS was bad I'd expect things to be worse.
I put the old CPU back in but haven't booted back up. I wasted about 8 hours on this already and right now am looking to throw in a new motherboard if that will fix things easily.
