Hello, I have just replaced my psu after it received water damage whilst replacing water cooling, I have now replaced it and now when I boot my PC it goes straight to bios with no options and both hdds are not visible, nowhere to be found, any ideas? Could the water damage have fried my hdds?

it was plugged in but not running, I then turned it on to train the loop and it blew, I then got the new psu installed it and everything is working fine except the hardrives

everything else is working connected to the board though, the 24pin wasnt plugged in when the psu blew, only the watercooling and the hard drives the CPU cable was plugged in but that's running in bios, literally only thing not showing is the hdds
