Windows 7 - Can't extract any files

I can no longer extract files that I download off the internet.

.exe, .zip, .rar, you name it, it will not extract.

I downloaded an nvidia driver update, and in the middle of the extraction it said that my file is corrupt. Same for any zip or rar files. (I tried using winrar, 7zip, WinMount3, Windows Explorer)

I ran chkdsk and Windows Memory Diagnostic and it seems like there are no problems.

I wonder if it has anything to do with my RAID5 configuration. I had to rebuild a harddrive twice since I installed 7100, both due to Windows crashing unexpectedly. I will probably be moving to a RAID1 config when I install RTM though, as I can no longer stand 40 hour rebuilds.

If anyone has any suggestions as to what else I can check, it'd be greatly appreciated.

Thanks!

I am having this same problem, it is driving me insane. I cant install near anything, and I cannot play games unless from Steam.

Hello Tarubox, and welcome to Windows 7.

You might see if doing a repair install may be able to fix this for you.

Hope this helps,
Shawn

I will try it out thank you.
