Blue Screen of Death with no error message

My system is crashing to a blue screen with no error message.

Can someone help me please.
I have had Microsoft Flight Sim X installed for a few months and it has run fine until now.
I don;t know why it's changed, but now every time i try to use it, the system crashes to a plain blue screen, no messages!
What can I do?

What have you installed since?

Check antivirus, check firewall, check memory, disc space, try defregmenting. Check for crapware, malware, everything ware, uninstall and reinstall. Think carefully about anything you may have done since installation.

If all else fails, think about the serious stuff; have you got a pukka Windows setup? Have you updated it lately?
