Hi everyone I am hoping you can help me set up a clean install of windows 10 or 8.1 64 bit edition on my 945P7AD motherboard 3.2 intel pentium processor 4gb based system. I have tried several versions of 64 bit OS and all of them fail to start properly after instal but 32 bit versions work without problems. This is a brand new motherboard (bought as a replacement for a failed one). I am hoping that someone on here can talk me through what I need to do in the bios to get this to work - cheers - Dave
