The following Dodgers have been smited by the JDK for their crimes against Jam:
All the girls! for picking on the JDK and damaging his already delicate self esteem!
The Basserd Who Nicked Copper's Stuff For the offense of nicking Copper's stuff. You are a tw*t, whoever you are and we all hope you get run over by a tram in Nottingham. Or Liverpool. Or whereever else they have trams!
Copper For the crime of playing with her Wii instead of her Jammie pals!
Well the first one, nvsvc32.exe, is for your graphics card...
Try going to the NVIDA website and downloading the latest drivers for it - that may help (although I think you did this already didn't you?). If not, they should have a tech help page that may help you sort it out. The problems with CoH are probably related to this cos it's a pretty graphics intensive game and if the drivers aint working properly, then you're kinda stuffed.
Have you had problems with your broadband cutting out at any other time?
As for the other two... no idea. They could be related to the nvida problem. Have you tried sending the error report to microsoft with the 'send error report' button? This usally links you to a web page that explains what the problem is and how to fix it.
I'm not a geek, so take this with a pinch of salt, but I think the last two might be due to some virus/spyware. Have you got adaware? Run that a few times and see if it finds anything nasty.
