  1. Hi :)

    More information needed ???

    All the best Brett :)
  2. Is this a Dell Dimension E520 desktop you're referring to? A bad PSU can cause this on a Dell tower, but if you've already done this you'll have to troubleshoot the motherboard. First try re-seating the RAM and any PCI(e) cards attached, and try to restart the system.
