ive recently tried to install a geforce mx 44064 mb ddr card but once hardware is installed the sys wont power up
possible card failure ?
sys running on dfi onboard graphics <661 fxmlv>
onboards need to be disabled first ?
help appreciated

need to know more about your setup.

Yes onboard always needs disabling but would not cause a total failure to boot.... are the fans running?

Newer cards do draw more power than older ones btw.
