Irritating Internet

Fun how small small things just tear the very fabric of a computer. For more than a week now my Internet connection has behaved exceptionally weird.
When I start Bittorrent or previously uTorrent then everything except for that said program that needs the Internet to work stops working. Or works very very badly. And from time to time bittorrent itself will stop responding, that keeps up for some time and then I get a BSOD with a PFN_list something. Very much irritating.
I´ve tried configuring everything as said in forums and it still doesn´t work. The only thing I have left is re-installing Win7 and installing every single thing again. Which isn´t as fun as it might sound.
The other solution I´ve thought up is moving all my HDDs to the NAS/Server computer I´ve been wanting to build for a long time and finally have put together. I just need to decide on a OS for that computer and then I´ll start using that.
To me it seems as if the bittorrent client is writing a lot of bad information to my memory, or some other bad driver is doing it. I don´t know which one, but I do hope that it is some other driver. But I don´t know. That´s why a reinstall of Win7 and starting from scratch would be a good choice. To see if some malicious firmware had gotten on the computer or not. Even though I´m protected by Panda Internet Security and it´s fully updated I guess some stuff can get trough anyway.
It is just my bad luck that I need the internet for school work and for other projects I´m trying to start up.
The BSOD and the answer Win7 gives me is that I have a problem with a driver. But when I check the solution, all I get is that I should run Windows Update, which is fully updated. All drivers that I have are the last one so it isn´t the problem there. What I do dislike as hell is that Win7 is not able to directly tell me which driver it is that is making me clench my fists in anger. It´s just a general “use Windows Update to check for updates”…
So something is very very wrong with this system as it is now. I just wish I knew what the problem was. I don´t think I should have to install other programs to get more information out of the information from a BSOD, it should be given directly to me.
And also, it´s hilarious that I have to use a internet connection to get the solutions when it doesn´t work. That´s really good system design there Microsoft, you make a solution center that demands that you´re online for it to even work.
I´m just so irritated at this all. Sorry for rambling on about it and while this means little to our readers it´s very irritating to me, so if anyone has any tips on what I can do or just want to laugh at me then go ahead, do so in the comments.
Thank you for your time.

Did you check the System Log file thing that records all the events? It should have whatever is bugging the crap out in there somewhere.

Yes, I checked the Event Viewer, it didn´t record the most recent BSOD but only took one that happend a couple of days ago.
But I haven´t checked any logs for the days to why the Internet would crumble. Anything special that I should look after?
Not that much of a hi-tech person anymore. I can use programs sure but with these kind of errors I´m kind of stuck.
