Newegg is making us login to see the list, maybe you can just post a list.
On the video card, you get drivers for the video card from the maker of the card, in this case you will directly to AMD because they will be the latest drivers. For the MB chipset, you get drivers from motherboard maker, and if you want just like the video card you can go directly to Intel to get the latest drivers. O yeah, AMD now own ATI, so thats why you would go to the AMD website lol, you would get getting video card drivers and not chipset or MB drivers from them.
Flashing a bios is not that hard there are some tutorials out there. Hopfully it will be a simple fix that you simply run the exe and it does everything. I have an EVGA 8800gt and the company put out a new bios that was very easy to flash the video card.
On the OS, realize if you get 4gigs of ram, the computer will only see 3gigs with a 32-bit OS. Only a 64-bit OS can see more than 3gigs.
