Some of those look pretty serious and some others appear to relate directly to your problem. Notably 6, 7, and 8. It may also be that they're connected to 3 and 4. So, the first thing I think you should do is perform a scandisk (right click on C: > select properties > tools > click the check now button. If it finds lots of errors I recommend you download a utility from the manufacturer of your hard drive to run some tests and if you can't find one from your hard drive manufacturer you can download the ultimate boot CD -->
http://www.ultimatebootcd.com/ and use one the ones on there. The IBM drive fitness test or the powermax utilities are the ones I use.
Once we know the hard drive is ok we can focus on your network which looks like it'll require a reinstall of TCP/IP.
