Question Installed a new psu and stuck in bios

[GoodOrNot]

I've recently bought a EVGA supernova 750w G+ psu and after I installed it, my pc started up and went to the bios and everytime I restart it, it goes back to the bios. How do I fix this?

honestly sounds like you may have unplugged your boot drive. check all connections you may have bumped something changing the PSU

maybe you coin battery went dead? The swap of the PSU might be coincidence.

step through bios and make sure the boot disk and RAM values show properly.
disconnecting the old PSU might have made it appear that your CPU or mem config settings have changed.
