Reinstalled windows 7 on samsung laptop. Lots of things not working.
I reinstalled windows 7 64 bit on my Samsung R580 and now a lot of things aren't working. It used to have windows 7 home premium 32 bit on it from the factory. The wifi isn't connecting, the ethernet port doesn't work/ isn't connecting to internet, the hdmi output doesn't work. I used to be able to change the brightness/volume using the FN key and the arrow keys and now that doesn't work. The taskbar used to be see through and now its a solid color and I can't get it to be see through again. I think that's because something with the chipset is wrong or the driver. There used to be a power setting called Samsung optimized and now that's not there either. I don't have any of the backup file/ disks either. I appreciate if anyone could help me out...I really messed this up.
