Sro stops responding at Banner

[TheDrop]

Well a few days ago my computer crashed and i had to reinstall the operating system. So i did so, and I installed SRO.
After downloading DirectX SDK, the sro launcher appeared. After i press the Start button, the banner and the gameguard appears (as usual), but then the Gameguard goes away and the SRO banner stays. It stays for a few minutes till my computer informs me that the program is not responding . SOMETIMES i get through the banner, but after the log in screen movie appears, the motion is soooo slow it shows like 1 frame every 2 minutes, and it stops responding again >.>
So i wanna know if there is a solution for my problem. Do i have to reinstall sro?

Thanks for any help

Did you re-install all the drivers after re-installing your OS?

Did you re-install all the drivers after re-installing your OS?

When i reinstalled my agent told me i still had 3 drivers to download, but i didnt get to the 3rd one. its something like R1777... and im not sure about the rest of the number. it is on my other PC, but I am having trouble getting it from there to this PC, and i cannot seem to find it anywhere else. should i try to download all the drivers available to me?

Edit: the driver i need is R177772 it seems, but i dont know if thats gonna solve my problem =(
Edit2: i downloaded R177772 and it still doesn't work >.<
