Went to Dell's website and downloaded bios v.2.4.1 update for an Inspiron 1501 laptop. When the computer re-booted it went kinda crazy. It searched for and installed all the hardware on the computer.It messed up all the appearance settings on my desktop. Is this normal? I did a systen restore thinking it would return everything to normal but it didn't. I reset everything so my desktop looks normal again. Hopefully I haven't screwed anything up but something just doesn't seem right. Is there any way reverse the changes I made?
