I have been getting the blue screen of death quite a bit lately. I was reading other threads and I do see that it would be helpful if I had a screen shot of the errors. If it happens again, I will get that. Otherwise, what can I do to fix my computer?

Without knowing the error, it is hard to tell - and sadly, knowing the error is not always conclusive. Most BSOD's are caused by a hardware (or driver) conflicts. If you just made some changes and the problems started right after, you might undo them and use System Restore to back up in time to a point just before the changes.

If it started after no changes by you, I would start by making sure the interior is clean of heat trapping dust and all cables are connected securely.
