If you have Windows Vista, it could be some sort of patch for the BIOS or for your version of the OS.
If you happen to have an extra pc around, take out that PSU and hook it up to the DELL 530 and see if it's a PSU issue. Look for any bulging capacitors (they might have black or brown residue on them) on the motherboard. If you have any of those, try replacing them (if you know how to solder it shouldn't be a big job).
Could either be bad PSU or MoBo.
Good luck!
