I am at a real loss here.

This set up was working before with NO ISSUES.
I had a virus that I was unable to fix and restored the PC to factory defaults.
I had issues with the PC, but it was related to the service packs.
They've been installed, and I ran all the updates.
I forget what it was, but after the restore I had an issue with something else.
So I ran the restore.
I actually did install the K-Lite codec pack, and then all the programs I used prior
(like MP3 Gain, MP3 tag, Utorrent and a few others).
With respects to playing media, all the files I test work on the PC itself.
I think another restore may be in order.
Question.................
I'll move all the media (which is limited anyway) and run the restore again.
Upon restore can I just install service pack 1 & 2 ? Or should I wait for the auto updates to
find and install them ?
The sole purpose of this 2nd PC is media streaming, so if it does not work the PC is not serving its purpose.
Perhaps when I did the restore I was premature in putting my torrents, programs, etc, back onto the PC.
