System Drive no longer showing in dekstop or finder ???

[Altair]

so i switch on my g5 this morning and notice that all my preferences have been reset but more worringly my System hard drive no longer appears on my desktop !! my 2nd internal drive appears fine though !!

the weird thing is the system drive is still working as i can boot into OSX and browse the drive from within finder using the side shortcuts to things such as "applications, documents, movies" etc...but the actual drive icon does not appear ANYWHERE. Iv gone to finder preferences and made sure iv got "show drives" selected but it still only shows my 2nd internal

iv run disc utility and done verify disc permissions and verify disc and both went fine but the hard drive icon still doesnt appear on the desktop or in the finder window

does anyone know a way to get it back ??

You might have changed your monitor's resolution or you moved your HD icon buried on the top right corner that you cannot see it. I have an idea. You could change the resolution like 1680 x 1050 or 1600 x 1000. It is in the Display from System Preferences. After you select the high resolution, you might see the HD icon. You drag it near the center. Then, change the resolution back to the original one that you like. After that, you drag it to the corner. That's about it.

I am not sure about a Startup Disk in the System Preferences.
