I have just got a new PC that I have built. The motherboard supports my processor BUT it needs to have a BIOS update first. Basically (I dont think there is but it would make it a hell of a lot easier) is there any way of updating my BIOS without having to find a compatible processor to use whilst I update the BIOS?
Download your new bios and get it ready for install via the floppy disk method. Your mobo manual will tell you how to do this. Boot up the PC with your new CPU and go straight in to the BIOS where there should be a facility to update it via floppy. Run through this process and when its finished reboot as instructed. Your CPU should now be listed during POST. You will not harm your CPU, the BIOS has safeguards against it.
It should at least get to the POST screen. If it doesn't then you need to check all cables are connected properly and are secure. Is the extra power cable connected to the motherboard? Remove any item not required (sound card, CD/DVD drives, additional hard drives, etc) and only use 1 stick of memory if you have more. Then try to boot.
