my screen

[Ramses II CP]

Brute Windows truth: If it doesn't happen regularly there is no fix. Which is to say, if you aren't doing something relatively specific which can be identified (And reproduced) as causing a BSOD then your instability is probably too broad to be addressed over the 'net.

That being said, the same general tips to improve stability apply to BSODs:

1. Windows Update!

2. Any recent hardware changes? Software?

3. Make absolutely sure your virus definitions are up to date!

4. Spyware/malware scanner like Spybot.

5. Clean out your registry.

6. Get the latest driver for your graphics card. If that doesn't help get the one recommended by the card's manufacturer and/or your machine's builder.

Good luck.

edit: I should've phrased that first part in the form of a question; Do you get a blue screen every time you boot up? Every time you launch some specific application?
