BSOD and crashes - help needed

Hello,
I've been having a bad day today. This afternoon I lost internet connection to my PC only but it came back about half an hour later. I thought it strange but was glad I had it again. I then noticed that windows update had found 10 important updates but could not complete installation so I'm not sure if this has something to do with my problems.
A little while later I had a BSOD..followed by many more.
I had no idea of the cause but tried a system restore. It would not reboot after this so I went into safe mode and it said that restore had completed.
After two attempts I rebooted in normal mode.

I have had repeateded browser crashes and game crashes since then and another BSOD.

I run Windows 7 64 bit and use the latest Firefox.
I'm including my minidump zip and really hope someone can help me.
I'm getting quite stressed. I'm really wondering if it is windows update as I've not changed anything else on my PC, except install a game expansion, for quite a while. (I have had someone mention my mouse driver but they were not very helpful in telling me which driver I should try. I have a Razer Diamondback 3G and I know that one of the win7 drivers is reputedly a source of crashes). I'm sorry if I do not understand how to do some things but will ask for more info if that is the case. I try.
I have a zipped copy of my minidump if required.

Thank you for any replies.

 

this is a personal thing with me, i don't do updates, if ya can chat i'm at laminagrove@hotmail.com, see if i can't help ya "live" the reason i don't care for updates is I like to do a clean install THEN add my programs, I'm goofy that way, hey, I just got a French Press coffee maker today, wow, happy birthday to me,
