still getting disconnected from BF3 pc

[#1]

ive been getting this problem now for months and months which made me give up trying to play games online. after about an hour of playing i always get disconnected from the games server. is there a way i could monitor my pc to check what actually happens when i do get disconnected to see whats causing it. ive tried turning the firewall off but i still get the same. it cant be a fault with the game as there has been many updates for it and im still getting it.

have  you looked at windows Event viewer ? > control panel > system & security > admin tools ?
but unless the game is crashing you wont see a lot,
1, is the game crashing or just losing connection , is connection fine while playing  ? are you seeing a red triangle in top right had screen ?
2, Turn UPNP off on your router
3 , Update punkbuster
4,update hardware drivers .
last thing what are spec,s of your PC  ie are you on minimum spec,s for game ?
a bit more info would help
PS bet Jim or strat moves this to gaming

thanx for the reply. the game doesnt crash at all. it just goes back to the server screen saying i was disconnected and i have to click on reconnect to the match. ive already tried with turning off upnp from last time i tried to sort the problem out. my pc spec is:
windows 7 64 bit
AMD phenon x4 955 processor 3.2ghz
4gig RAM
ATI radeon hd 5700 1 gig
ive also updated the driver for the graphics card and downloaded latest punkbuster. i only seem to be getting it while playing bf which is strange

try this
Click on the windows logo/start button
-In the searchbar, type services.msc
-Press ENTER
-A list of services should now be in front of you.
-Click "extended" tab
-Search for "UPnP host devices" or something similiar (the description is something like: Allow hosting of UPnP devices blablabla)
-Right click it
-Click Properties
- there is an option  "startup", in the general tab. You can choose between: Automatic (delayed startup), Automatic, Manually, Disabled. You must choose Disabled.
-Click on "stop service"
-Click "apply" and close that little windows.
-Search for "SSPD discovery" and do the same things that you did above.
-Close everything
-Reboot.

A friend had a similar problem , EA support was poop    unfortunately the game  when running  is Ace  but so many bugs with Battlelog & silly Origin .
the only thing you
could try as a last resort is uninstall with Revo uninstaller , Game & origin , clean registry with C cleaner , then reinstall 
i dont think its your connection it sounds like a BF Bug .
PS BF is the only game i play

seems like the only thing left to try really. i am tempted just to upgrade my graphics card and ram and do a clean install of evertyhing on the pc as its full of crap at the moment. whats your name on it ill give u an add
