I have a Microstar 6160 socket 370 in one of my many pc's the board supports up to 1.1ghz so I bought a second user Celeron 1.0ghz and it was tested as working.
I installed it onto the mainboard switched it on everything fired up as normal but there was no display I change the video card, still nothing,I tried another monitor and still nothing.
I put the old CPU back in (also a Celeron) and everything worked fine.
Any ideas how to fix it anyone ???
