I have an Asrock M3A790GMH 128M MB - Win 7 - 5MB .
Worked fine for 5 months - now I have to switch on & off 3 to 15 times
before it posts / starts up.
Once it does start up - works fine (until next time I have to switch on).
I have tried just the MB (no components whatsoever) and it does not post.
Any ideas ?
