Blue screen!!! plz help me!! >:-[?

I had 9 months of blue screen problems. In the end I discovered that despite what the messages said the real problem was caused by the memory cards. I took them out and replaced them in a different order and my computer has behaved itself since. A friend told me that there are often problems caused by contacts that have not been cleaned up during manufacture. A quick removal of the cards can put that right. Good luck.
