Removed Driver With DriverSweeper - BlueScreen

I wanted to update my chipset/LAN drivers for my mobo because I got some strange issues in my network.

Let's start from the begining. There are 2 computers in lan, one running windows 7 and the other on XP. While ago, net provider cut me up for like 4 days and since then I couldn't get my windows 7 to connect to lan. It said there was come connection issues and it couldn't find any solution for that (yellow triangle appeared next to the "LAN monitors" icon in tray). I couldn't connect even to the local network while XP comp connection still works fine, i'm writing from it now.

So I ended up doing this stupid thing, "updating chipset/lan" drivers for my mobo. Firts I wanted to remove old driver as I used to do it on my old XP - driverSweeper in recorvery mode. When I rebooted system it was too late. Blue Screen flashed in front of my eyes while startup animation was playing and the computer resets. Later I found out it said 0x0000007b. Nothing I could thing of helped to fix it. No restore points were taken (no auto, no manually done by me, oh you stupid), WinRE with fixing tools, startup fix, memory thing - nothing.

Mother board isn't in fact broken or something, I still can run my Ubuntu LiveCD. I managed to burn WinRE thanks to that. Even though it was the same damn thing as on the Windows 7 installation disk.

Is there any hope for this issue? Only thing I know is that my system is missing Chipset drivers and it can't manage to fix by itself.
