I'm running into an issue that's got me a bit stymied. Some times when I reboot my system my drives go missing (three HD drives and DVD burner.) About the only way I can get them to show up again in the BIOS is to power down and remove the power cable for a short while. When the system is up everything works fine so I'm not sure what to look at. I've tried going back to default settings in the BIOS thinking that might be an issue but that doesn't help. I've also run the numbers on various power calculators and my PSU has about 60-100 watts extra depending on which calculator you look at. (It's also a decent calculator since it is an Enermax.)
Any ideas as to what I should look at?
