Help HTC aria Booting problem

[Fido.genial]

Hi,

My HTC aria phone fell into water few days back..i have dried it properly now if i turn on the phone i can see a screen which says Use the volume buttons and the power button to select the 'FASTBOOT' or 'RECOVERY' .. option. But the problem is volume button & power button is not working for some reason.. is there any other way that i can do the boot.. by connecting it to computer and controlling the options... ? what could be the problem do you think..

thanks
