Not the icons but the screen res changed randomly. Sadly it took a month but it became clear when the video card finally put out a puff of smoke and the machine halted.
Your post has nothing about the machine or its care.

Recently, I started experiencing some screen problems. Firstly, all my
icons disappeared during a session (I was able to replace them).
When I next signed on, my screen resolution had changed from 1024x768
to 1280x768. I have changed it back a number of times while under my
user account and as an administrator, but it reverts to 1280 whenever
I sign back on.
Lastly, I have tried to realign certain items on my task bar with out
success. I want to move a digital clock and the network icon area to
the far right while keeping program/configuration widgets on the left.
They will not move.
Any help with the display size and the alignment would be appreciated.
Thanks...John
