Can't Setup Network / Internet Connection

I've been watching my PC-s HDD for months and I saw that something takes up way to much space, yesterday I checked and Windows said that I have 160 GB Free / 883 GB But when I selected all files in my E: even hidden files and checked their properties / size, it said its only 440 GB. So I was missing another 283 somewhere in this partition. I used the windows cleanup tool and it gave me back some of the space, but it wasnt 283 GB. I checked and checked, then I found a program called WinDirStat which shows you how much space you have and stuff, then I found this: [URL]Then I found out that WinDirStat cannot access the System volume informations and this unknown is that. Then I googled stuff up again and found this:

Code:

1. To see the space allocated and used for SVI:

- Open Command Prompt with �Run as Administrator� option

- Type in: vssadmin list shadowstorage

- You will see Used Space, Allocated Space and Maximum Space for SVI

2. To see the restore information stored therein:

- Use in the same console command: vssadmin list shadows

3. To resize the maximum allocated space:

- Type in command: vssadmin resize shadowstorage /on=[here add the drive letter]: /For=[here add the drive letter]: /Maxsize=[here add the maximum size]

- E.g., vssadmin resize shadowstorage /on=C: /For=C: /Maxsize=4GB

- You will see a prompt confirming resize done

- You can check the status again using the command discussed in point 1 above

4. Just to get rid of the space already consumed, but sticking to the same size of max-size as before:

- Do actions as per point 3 to set the max-size t, say, 1GB

- If you check now, most likely you�ll see that used space is now 0KB

- Do the resize again and set it back to what it was before

- Check your disk space availability in Windows Explorer, you should see the reclaim is done!I did what this guide said and it deleted the system volume information from my E: drive and I had my 440 GB back. BUT!At this part I HAD internet connection. I shutdown the PC, went to eat and do stuff, then I came back and got a blue screen right after the win7 logo (before the log in screen)I couldnt read what it said, because the PC restarted itself (even tho it is set NOT to restart so I can read the errors...wierd!)Then it started repairing itself, restarted, asked for a chkdsk, fixed millions of errors then restarted and I logged in just fine.But in the bottom right corner I seen a big ugly red X over my network connections, so naturally I went out my room, restarted modem and router then came back. Waited some mins, checked the modem and router again but they had internet. I started my sisters PC and her PC had internet.I checked everything I could, but I couldnt revive the internet, I cant join to any network (home, private, work) and I cant even see any. I only see dial up connections, hamachi and tunngle.Then I tried to resintall the driver. Deleted driver, restart PC, win automatically installed the nvidia driver for me, but still no internet. Then out of couriosity I started my Virtual PC (win xp) to check if it has internet connection or not. And it has! I am writing from the Virtual PC now.So the network card is working perfectly, no hardware damage.I googled stuff up again to find a solution and then I found this thread: Loopback Pseudo-Interface 1I did what it said there and my result was different:
