For those of you who have older desktops that make a funny (grinding) noise for a while, then blue screen or crash, crack open those cases and dust with canned air.
If your video cards have fans on them, pull them out, clean the dust out of the fans and heat sinks. I use a cotton swab soaked with alcohol, but I am sure there are better solutions.
Grinding sounds are usually failing or failed fans, and they should be replaced. Check them by having the case open and turning on the power. All fans should spin. If one doesn't, replace it.
