Reinstalling Sony Vaio BIOS

Rate this question

Question

Hi everyone,

I recently had a computer crash with my Sony Vaio VGN-FZ31Z, due to a software failure.

I had it repaired by a technician (not under warranty anymore), and I lost all partitions containing the Sony recovery software.

After a lot of work downloading the original drivers and reinstalling them (in the correct order :mda: ) I am now running Windows 7 (originally Vista was installed) but of course without all the original Sony software (like Sony Update etc...).

But now I've noticed that my BIOS is acting weird. I just found out that I can't install the original NVidia driver anymore, neither on Windows 7 or Vista. Once I try to do that, and I reboot, it gives me a bluescreen and I get all kinds of weird colored dots and striped on my screen. It says "Page fault in non-paged area", so I run Windows startuprepair and it fixes it (by uninstalling the Nvidia driver). Also, on startup, I get the Vaio logo, but it's a bit deformed (pixelated, warped, etc...) similar to this: http://www.google.be/imgres?q=sony+vaio+startup+logo+pixelated&start=197&um=1&hl=nl&sa=N&biw=1280&bih=709&tbm=isch&tbnid=twcI_MWsqlrRDM:&imgrefurl=http://article.wn.com/view/2012/05/24/Chips_Not_Just_for_Gamers_Anymore/&docid=hpJEbWV4BkagwM&imgurl=http://i.ytimg.com/vi/JDl-ZxA2G_Y/0.jpg&w=480&h=360&ei=x3ySUNK-EeG_0QWRh4CYDA&zoom=1&iact=hc&vpx=417&vpy=30&dur=398&hovh=194&hovw=259&tx=82&ty=87&sig=112231823195252370857&page=9&tbnh=151&tbnw=240&ndsp=25&ved=1t:429,i:298

Also, I can't get my battery to work properly anymore. My technician says he doesn't know how to fix it, because the BIOS is probably corrupt or something.

I have never changed anything to it, it's still the original BIOS.

Do you guys know a (safe) way to reinstall the BIOS or to repair it?

Thank you very much.
