Laptop keeps crashing!

My laptop keeps crashing and restarting and it's driving me nutty! They are is no warning - a blue screen appears with some text but it disappears too quickly for me to read it. When the laptop restarts it notifies me that there was an error and window will try and find a solution for the problem.

Thks for your reply.
I don't think I have AVG antivirus. The laptop is exactly the same as it was when I bought it from Dell. I came with McAfee protection (?). I downloaded MSN and yahoo messenger and the Nokia Suite. But that was sometime ago. The problems only started occuring when I installed the updates - once in May, June and the latest earlier this week.
It crashed again this morning and this time saying something about 'chkdsk' needs to be checked. Then there was a succession of error messages about things in my c drive.
I will try your option below and reply if they don't work. Thanks again, appreciated.
