Hiya,
I've been recieving these stop errors since yesterday and the only think i installed new was the windows live messenger the latest one- 14 and upgraded bbc iplayer.

It says the following file has caused this problem but doesn't list which file and just lists this stop error. I recieve it when i wake my machine up from standby and hibernate. Any ideas what the problem is?

If you weren't receiving any stop errors before the updates and you are receiving them now it is a good bet the issue lies with your updates/installs.
