So, I bought a new cpu for my pc, a xeon E5430. I looked around on the internet and found that it should work. I modded the mobo and it booted into windows. Then I restarted the PC and now it won't get past the windows logo. Not even when I try to boot from a usb stick that has windows 10. It works fine with another cpu (E6400). I have tried updating bios. It booted once but it said in task manager that it was running the E6400 even though the E5430 was in the pc. In CPU-Z it said that it was running the xeon but at the E6400 speeds. Then I restarted and it won't boot again.
