Napalm Riot

So...My desktop was broken for a while, and it turned out it was a bad stick of memory. It is since working again, I have discovered it cannot go online. The wireless card APPEARS to be working, as it detects, and sometimes connects to, the router. When I go to go online, it gives a "page cannot be displayed" error. When I switch to ethernet cable, and plug it into the router, it connects, but still no pages displayed. I go to repair the ethernet connection, and get a "Failed to Query TCPIP Settings of the connection, cannot proceed." error.

typing ipconfig into the command prompt yields "an internal error occured, the request is not supported."

now, I have tried

Code:

netsh int ip reset resetlog.txt

but that yields no fix. I have tried coping the known-to-work tcpip.sys and ndis.sys files from this computer (laptop) as well as 3 separate repair programs, nothing worked. I am faced with the delimma of reinstalling windows, but I have so much data that needs backing up, and no where to put it, and not enough cash for an external HDD. Also, My HDDs (2x500Gb) are formatted RAID-0, and I do not know how re installation will affect that.

I have heard ideas of a repair install, but clicking "upgrade" instead of "fresh install", but will that mess up the RAID?

*is frustrated*

any ideas?
