Flash it back to the original bios but make sure you uninstall drivers first.
Once flashed back to the original bios restart the pc then install drivers then change your background picture.

When i install my drivers aero does no always auto work so i have to just change the background pic and this sorts it out.

Personly i woulden't risk using different bios files due to small differences in the GPU's,
Flashing a 512mbs bios to a card with 1gig of ram is asking for problems.

So many things can be different such as the amount of shaders different makes of ram chips different volts and timings.

I really would just try the original bios then install drivers and try changing your background pic.
If that dosen't work then try to at least find a 4830 bios rather than a 4850.

If your card is sapphire i would sugest trying to find the right bios for your card and not one from a different manufacturer.

Have you tryed the sapphire 1gig bios files?

There are 3 files by sapphire on this site, I have linked all 3 in my above post.
I'm not 100% on the differences though.

The problem is there are loads of different makes of the same card you have so you can't expect bios files to just work as there are lots of little things that could cause problems and this is why a lot of us here don't recommend flashing a GPU inless there is no other option.

Good to hear you finaly fixed your problem

none of the work on your BIOSes let you know ...
As Animal just said there are many different reasons for a BIOS to work or nor work, flat out saying that none of the BIOSes on TPU is just wrong.
